What Maryland State Parks Does the Appalachian Trail Go Through?

The Appalachian Trail (AT) is one of America’s most legendary long-distance hiking paths, stretching approximately 2,190 miles from Georgia to Maine. Along its winding journey through 14 states, the trail passes through an array of ecosystems, landscapes, and protected public lands. Maryland, nestled in the Mid-Atlantic region, plays a surprisingly significant role in this hiking odyssey. Though only about 41 miles of the AT run through the state, that short stretch is packed with history, natural beauty, and rugged terrain.

One of the most frequent questions from hikers, outdoor enthusiasts, and nature lovers is: What Maryland State Parks does the Appalachian Trail go through? The answer reveals not just scenic landscapes but also the state’s commitment to preserving wilderness, promoting outdoor recreation, and honoring the legacy of the AT.

In this comprehensive guide, we’ll explore the Maryland State Parks directly influenced or intersected by the Appalachian Trail, provide insights into trail conditions, notable landmarks, and key access points, and highlight why this section of the AT deserves more attention from adventurers.

Overview of the Appalachian Trail in Maryland

Before diving into specific parks, it’s essential to understand how the AT traverses Maryland. The trail enters the state from the south, crossing the Potomac River at Harpers Ferry, West Virginia—the traditional psychological midpoint of the trail—before heading roughly northward through the Catoctin Mountains. It eventually exits at the Pennsylvania state line near Pen Mar.

While Maryland doesn’t host the most rugged or high-elevation sections of the AT, its portion is historically and environmentally rich. It passes through varied terrain, including hardwood forests, rocky ridgelines, rolling hills, and the iconic Catoctin Mountain range. Along the way, it skirts or passes directly through several significant protected lands, including both state parks and federal areas like the Catoctin Mountain Park.

State Parks Intersected or Adjacent to the AT in Maryland

Although the Appalachian Trail doesn’t pass through multiple Maryland State Parks in the conventional sense—due to Maryland’s limited number of large state parks—the AT does run through or along the boundaries of one major Maryland State Park and is deeply connected to another that shares administrative and ecological ties. Additionally, there are key access points, trails, and facilities managed by Maryland’s Department of Natural Resources (DNR) that support AT through-hikers and section hikers.

The primary Maryland State Park associated with the Appalachian Trail is:

Catoctin Mountain Park (State Park Section)

Catoctin Mountain Park is often confused with a federally managed park due to its name and the presence of Camp David, the presidential retreat located within its grounds. However, a significant portion of this scenic area is officially designated as Catoctin Mountain State Park, managed by Maryland DNR.

The Appalachian Trail runs directly through this state park for approximately 12 miles, offering some of the most memorable hiking experiences in the state. The trail utilizes the Blue Blazed Trail system within the park, paralleling or intersecting with components of the AT.

Notable features along this section include:

• Hoye-Crest Summit: The highest point on the AT in Maryland, reaching 2,145 feet above sea level.
• Short Hill Mountain: A rocky, winding climb that offers panoramic views of the surrounding valleys.
• Wolf Rock and Chimney Rock: Unique geological formations popular with day hikers and photographers.

The AT enters Catoctin Mountain State Park from the south, near Cunningham Falls State Park. Hikers enjoy well-maintained trails, interpretive signage, and lush forest cover. Park facilities—such as the park visitor center, restrooms, and picnic areas—make this a popular resupply and resting point.

Cunningham Falls State Park

Cunningham Falls State Park, located near the town of Thurmont, is another key Maryland State Park in close proximity to the AT. While the Appalachian Trail does not pass directly through the main recreational areas of the park, it traverses near its western boundary and intersects with the Falls Trail Loop and other connector routes.

Cunningham Falls is home to Maryland’s largest waterfall on a stream—a 78-foot cascade that drops through a rocky cleft into a serene pool below. The park also features:

• Historic stone quarry and remnants of the Civilian Conservation Corps (CCC) developments.
• Maryland’s largest natural lake: Big Hunting Creek Lake.
• Over 20 miles of hiking trails with varying difficulty levels.

A short connector trail exists between the AT and the park’s northern trailheads, allowing AT hikers to access visitor amenities, water sources, and a chance to view one of the state’s most scenic natural landmarks.

Though not on the main AT corridor, Cunningham Falls State Park serves as a vital support zone for backpackers, offering camping, shelter, food resupply, and emergency services. It’s not uncommon for thru-hikers to detour into the park at least for a day to rest and refresh.

Federal vs. State Park Overlap in the AT Corridor

A unique aspect of the Appalachian Trail in Maryland is the blending of federal and state jurisdictions. The trail is managed cooperatively by the Appalachian Trail Conservancy (ATC), the National Park Service (NPS), and state agencies. In Maryland, much of the AT runs through Catoctin Mountain Park, which is federally managed by the NPS, yet it adjoins and overlaps with the state-designated Catoctin Mountain State Park.

This distinction is important for hikers to understand. While they may enter a federally protected area, the ecological, trail, and visitor experiences are often indistinguishable from nearby state-operated lands.

Shared Trail Systems and Blurred Boundaries

The AT takes advantage of interconnected paths maintained by both state and federal agencies in Maryland. Trail signage, maintenance, and safety protocols are coordinated across these jurisdictions. For example:

This collaboration ensures that even though the AT doesn’t strictly crisscross multiple Maryland State Parks in a linear fashion, the infrastructure supports continuous hiking with consistent quality.

Other Nearby Protected Areas Influenced by the AT

While only two major Maryland State Parks are tangentially involved with the AT, several other conservation areas, forest preserves, and wildlife management areas contribute to the hiking experience.

Pennsylvania Border Lands: Green Ridge State Forest Proximity

Although Green Ridge State Forest lies west of the AT’s main corridor, parts of it are within a short distance from the trail near the Mason-Dixon Line. The forest, managed by Maryland DNR, serves as a buffer zone and offers trail extension opportunities for hikers seeking alternative routes or side excursions.

Gathland State Park (Historical Site)

Located near Burkittsville, Gathland State Park is a lesser-known but historically significant park named after journalist George Alfred Townsend, who used the area as a summer retreat. The park includes the War Correspondents Memorial Arch and old stone cabins.

While the AT bypasses the park to the east, a connector trail links the two, and the area is frequently used by hikers for interpretation and rest. Its proximity makes it a relevant point on AT maps, and it’s often referenced in trail guides as a cultural stop.

Hiking the Appalachian Trail in Maryland: What to Expect

Understanding the landscape, climate, and challenges of the AT in Maryland is crucial for both novice and experienced hikers. Here’s what you can expect on this portion of the trail.

Trail Conditions and Terrain

Maryland’s section of the AT features moderate elevation changes, with the highest point at Hoye-Crest. Unlike the steep climbs in Virginia or Pennsylvania, Maryland’s terrain is rolling and forested. Nevertheless:

• Rocky sections: Especially near Short Hill and the Catoctin ridgeline can be treacherous when wet or icy.
• Forest cover: Thick deciduous canopy provides shade in summer but reduces visibility for navigation.
• Muddy areas: Low-lying sections near streams and creek crossings can become slippery after rain.

Trail maintenance in Maryland is consistent, with regular inspections and volunteer clean-ups supported by the ATC’s Potomac Appalachian Trail Club (PATC).

Seasonal Considerations

The best times to hike the AT through Maryland are:

Wildlife and Nature Encounters

Maryland’s segment of the AT teems with wildlife. Hikers often encounter:

• White-tailed deer: Common in early mornings and dusk.
• Black bears: Rare but present—know food storage protocols.
• Bird species: Including woodpeckers, warblers, and the elusive barred owl.
• Reptiles and insects: Ticks and mosquitoes are prevalent in warmer months.

Always follow Leave No Trace principles, especially regarding wildlife and trash disposal.

Access Points and Trail Towns in Maryland

Though not a state park, access to the AT is facilitated by several trail towns and parking areas within or near public lands. These locations are critical for resupply, rest, and trail navigation.

Key Trailheads Near State Parks

• High Rock Trailhead: Located just outside Catoctin Mountain State Park, this paved parking area provides AT access and is PATC-maintained.
• Cunningham Falls North Parking: Closest trailhead to the AT near the state park boundary.
• Fox’s Gap: Offers a scenic entry point into the ridgetop trails of Catoctin.

Trail Towns Supporting AT Hikers

Maryland’s AT corridor is supported by several trail towns that offer vital services:

• Harpers Ferry, WV (nearest town to AT’s southern MD entry): Full amenities including hostels, food, gear repair, and the ATC headquarters.
• Boonsboro, MD: Close to southern trail access; offers cafes and motels.
• Waynesboro, PA (north of Pen Mar): Resupply point just beyond the Maryland border.

These towns often serve as “refuge” points for hikers traveling through the state—particularly because formal camping is restricted near certain sections of the Maryland AT.

Preservation and Volunteering Opportunities

One of the strengths of the AT in Maryland is robust stewardship. Multiple organizations, including the PATC, Maryland Department of Natural Resources, and the National Park Service, collaborate on conservation, maintenance, and education.

Volunteer with the Potomac Appalachian Trail Club

The PATC is one of the most active trail clubs on the AT, responsible for maintaining over 200 miles of the footpath, including the entire Maryland section. Volunteers are always needed for:

• Trail clearing and erosion control
• Rock step construction
• Signage and blaze maintenance
• Wildlife monitoring

Interested individuals can sign up for regular work trips or guided maintenance hikes through the PATC website.

Educational Programs and Guided Hikes

Both Catoctin Mountain State Park and Cunningham Falls offer ranger-led hikes, environmental education programs, and interpretive walks that incorporate the AT. These are excellent opportunities for families, school groups, and weekend adventurers to learn about:

• The history of the Appalachian Trail
• Forest ecology of the Catoctin Mountains
• The legacy of the Appalachian Trail Conservancy
• Wildlife conservation efforts

Unique Features of the AT in Maryland

While brief in length, Maryland’s stretch of the AT has several unique features that set it apart.

The Psychological Halfway Point

Harpers Ferry, where the AT crosses into Maryland from West Virginia, is considered the “psychological halfway point” of the trail. Thousands of thru-hikers stop here mid-journey to celebrate progress, resupply, and reflect.

The ATC’s visitor center in Harpers Ferry includes exhibits, orientation programs, and the “Zero Milestone”—a symbolic marker where hikers track their journey.

Hoye-Crest: Maryland’s AT Summit

Located on Backbone Mountain near the West Virginia border, Hoye-Crest is not only the highest point in Maryland on the AT but also one of the few mile-high points on the entire trail. The marker at the summit shows elevation and latitude with a plaque noting its distinction.

Though modest compared to the Smokies or White Mountains, reaching Hoye-Crest feels like a milestone—especially when emerging from the dense forest into open, rocky terrain with sweeping views.

Historical Significance

Maryland’s AT segment passes through land rich in human and environmental history:

• Civilian Conservation Corps (CCC) Legacy: Many trails, shelters, and roads in Catoctin Mountain Park were built by CCC crews in the 1930s.
• Civil War Sites: Proximity to Antietam and other battlefields adds historical context.
• Early Trail Development: Maryland was part of the original 1920s planning efforts by Benton MacKaye, the AT’s founder.

These layers of history enrich the hiking experience, turning every mile into more than just a physical challenge.

Conclusion: Maryland’s Role in the Appalachian Trail Experience

So, what Maryland state parks does the Appalachian Trail go through? While the AT technically passes directly through Catoctin Mountain State Park and skirts the edges of Cunningham Falls State Park, its presence extends beyond strict geographic boundaries.

Maryland’s unique role as the midpoint of the trail, its blend of state and federal land management, and its contribution to trail culture make it more than just a brief stopover. Hikers gain not only physical respite in scenic, forested parks but also a deep connection to the legacy and stewardship of one of America’s greatest footpaths.

Whether you’re a seasoned thru-hiker or a day explorer looking to walk a portion of the AT, Maryland’s state parks offer a gateway to adventure, history, and natural beauty. From the cascading waters of Cunningham Falls to the rugged summit of Hoye-Crest, the Appalachian Trail in Maryland is a hidden gem well worth discovering.

If you’re planning your journey along the AT—or just curious about how this iconic trail weaves through the Mid-Atlantic—don’t overlook Maryland. Its parks may be modest in number, but their impact on the trail experience is anything but small.

Which Maryland State Parks does the Appalachian Trail pass through?

The Appalachian Trail traverses through several protected areas in Maryland, including portions of Maryland State Parks such as Greenbrier State Park and rocks state park. While the trail doesn’t pass directly through the main recreational areas of many parks, it travels along adjacent public lands, including state forests and watershed areas. Greenbrier State Park is notable because the trail runs along its eastern boundary, providing hikers with access to picnic areas, camping, and a swimming lake nearby. The park is located in Washington County and serves as a popular resupply and rest point for thru-hikers.

Additionally, the Appalachian Trail follows the Appalachian Trail corridor through Maryland, which is managed in part by the Maryland Department of Natural Resources. While not every state park has a direct trail crossing, the AT winds through state-owned lands that are contiguous with or near parks like Cunningham Falls State Park and Gambrill State Park. Hikers may access these parks via short side trails. Maryland’s section of the trail is relatively flat compared to surrounding states but includes scenic views from ridgelines and access to well-maintained trail shelters and campsites.

Is the Appalachian Trail fully within Maryland State Parks?

No, the Appalachian Trail does not run entirely within Maryland State Parks. Instead, it primarily follows a corridor of public and protected lands, including sections managed by the National Park Service such as the Chesapeake and Ohio Canal National Historical Park and U.S. Forest Service lands like the Catoctin Mountain Park. While parts of the trail are adjacent to or cross near state parks, much of it travels through rolling farmland, state forests, and privately conserved parcels under conservation easements. The trail’s path in Maryland is carefully coordinated between multiple agencies to preserve the hiking experience.

However, several Maryland State Parks serve as important access points, resupply locations, and recreation hubs for Appalachian Trail hikers. For example, Greenbrier State Park offers water, camping, and road crossings near the trail corridor. Though the AT doesn’t travel through the main picnic or lake areas, its proximity makes it a practical stopping point. Other state park areas, such as those in Frederick and Washington Counties, offer trailside amenities and emergency access routes, contributing to the trail’s overall support system in the state.

Can I camp at Maryland State Parks while hiking the Appalachian Trail?

Yes, you can camp at or near certain Maryland State Parks while hiking the Appalachian Trail, though regulations vary by location. Greenbrier State Park is one of the few state parks with designated campgrounds close to the AT, offering tent and RV sites with basic amenities such as restrooms and potable water. Hikers often use this campground to recharge or take a zero day. However, overnight camping directly on the Appalachian Trail within state park boundaries is typically restricted unless done at official, designated backcountry sites.

Backcountry camping along the AT in Maryland is usually permitted at established shelters and designated thru-hiker sites spaced roughly every 8 to 10 miles. These sites are maintained by trail clubs and are located on public land managed by federal or state agencies. While some state parks may allow backcountry camping with a permit, it’s essential to check with the Maryland Department of Natural Resources or the Potomac Appalachian Trail Club for current rules. Violating camping regulations can result in fines and harm the trail’s long-term access.

How long is the Appalachian Trail through Maryland?

The Appalachian Trail spans approximately 40.9 miles as it passes through the state of Maryland. This section is known for being one of the flattest and most accessible portions of the entire 2,190-mile trail, making it a popular destination for both day hikers and long-distance backpackers. It begins at the Pennsylvania-Maryland state line near Pen Mar Park and travels south through the rolling hills of Washington County, crossing roads numerous times before entering the more rugged terrain of the Catoctin Mountains near the Maryland-Virginia border.

Despite its relatively gentle topography, Maryland’s stretch of the AT still offers scenic beauty, including views from ridgelines and several rustic trail shelters. Key landmarks along this route include Weverton Cliffs, Gathright Shelter, and the trail’s crossing of South Mountain. The frequent road crossings in Maryland—more than in any other state—make resupply and support easier, but also require hikers to remain vigilant around traffic. Overall, the Maryland section serves as a transitional, low-elevation passageway between Pennsylvania’s rocky terrain and Virginia’s more challenging climbs.

Are there hiking shelters along the AT in Maryland State Parks?

While there are no official Appalachian Trail shelters located directly within the boundaries of most Maryland State Parks, several shelters are situated along the AT in close proximity to state-managed lands. For instance, Gathright Shelter lies just outside the eastern edge of the Greenbrier State Park area and is maintained by the Potomac Appalachian Trail Club. This three-sided shelter includes a nearby water source and serves hikers traveling through the southern part of Maryland’s AT corridor.

Other shelters like Indian Run and High Rock are positioned along the trail within state or federally managed parklands, though not necessarily in designated state parks. These shelters typically offer space for 6 to 8 hikers and come with a wooden bench, an adjacent privy, and a marked tent pad. Hikers are encouraged to pack out waste and follow Leave No Trace principles. While state parks themselves may not host shelters, their proximity to the AT route enhances safety and accessibility for long-distance travelers.

What kind of terrain can I expect on the AT in Maryland?

The terrain along the Appalachian Trail in Maryland is generally moderate, with gentle elevation changes compared to the more rugged sections in Pennsylvania and Virginia. The trail winds through open farmland, rolling hills, and forested ridgelines, primarily along South Mountain. Hikers can expect long stretches of soft, well-maintained dirt and rock pathways, with occasional paved road walks near towns like Boonsboro and Harpers Ferry. Maryland’s section is frequently referred to as a “connector” because of its flatness and high number of road crossings.

Despite the relatively easy topography, Maryland offers scenic highlights, including panoramic views from Weverton Cliffs over the Potomac River and access to historical trail sites. The region’s geology features metamorphic rock formations like quartzite and granite, contributing to durable footpaths. Seasonal weather can affect trail conditions—hot, humid summers and muddy spring trails are common. However, the accessibility of water sources, road access, and nearby parks such as Greenbrier make this section ideal for beginners or those looking to break up longer stages of the thru-hike.

How do I access Maryland State Parks from the Appalachian Trail?

Access to Maryland State Parks from the Appalachian Trail is often achievable via short spur trails or road crossings. Greenbrier State Park, for example, can be reached via a well-marked side trail that connects to the AT near the park’s eastern edge. This route leads hikers to camping areas, restrooms, and a freshwater lake used for swimming and fishing. Other parks like Cunningham Falls State Park and Gambrill State Park are accessible via local roads or connector trails that may require hitchhiking or shuttle planning.

Hikers should use trail guides or apps such as Guthook or A.T. Guide to identify precise access points and distances. The Potomac Appalachian Trail Club (PATC) also provides detailed maps and maintains much of the trail infrastructure in the region. While not all parks are directly adjacent, their proximity makes them viable for rest days or resupply. Always check closure notices, obtain necessary permits, and practice responsible recreation when leaving the main trail to visit nearby state park facilities.
