Swallow Falls State Park

Swallow Falls State Park, in the Allegheny Highlands of Garrett County near Oakland, is arguably the most scenically beautiful state park in Maryland — a 257-acre gem protecting Maryland’s highest waterfall (Muddy Creek Falls, a 53-foot plunge), an ancient old-growth eastern hemlock gorge (one of the few remaining old-growth forest stands in Maryland), and the Youghiogheny River gorge, with a 1.5-mile trail loop linking the waterfalls and the ancient hemlocks in a continuous scenic experience.

The park’s combination of dramatic falls, ancient hemlock trees (some over 300 years old), clear mountain streams and the wild Youghiogheny Gorge creates an Appalachian forest experience far removed from anything else in Maryland. Henry Ford and Thomas Edison reportedly camped here in 1918. Swallow Falls State Park is a treasured natural icon of Maryland.

Swallow Falls State Park offers hiking the 1.5-mile trail loop through the old-growth hemlock gorge, past Swallow Falls (a broad, multi-tiered cascade on the Youghiogheny River), the smaller Tolliver Falls, and the main attraction, Muddy Creek Falls (Maryland’s highest waterfall — a 53-foot plunge into a rocky pool), camping in the park campground (reservations required in summer — a popular and beautiful campsite in the hemlock forest), swimming in the Youghiogheny River at the designated swimming area, birding (the old-growth hemlock gorge supports blackburnian warblers and other Appalachian-forest specialists), and photography of the waterfalls and hemlocks. The waterfall loop, the old-growth hemlocks and Muddy Creek Falls are the singular draws.

Spring (April through June) is the finest season — the waterfalls run at their fullest with snowmelt and spring rain, the wildflowers bloom on the gorge floor, the warblers arrive in the hemlock gorge (blackburnian, Canada, magnolia warblers) and the temperatures are ideal for the gorge trail. Fall brings the hardwood color contrasting with the evergreen hemlocks — beautiful. Summer is the busiest season (the campground is popular and the park is crowded on weekends) but the falls and hemlocks are beautiful year-round. Winter, when the falls freeze and the hemlocks hold snow, is hauntingly beautiful and nearly crowd-free. Spring for the fullest falls and warblers is the highlight.

Swallow Falls was a timber camp site in the 19th century — the hemlocks were stripped of their bark for tanbark (the bark was used for tanning leather) but the trees were too large and valuable to fell, and some survived. Henry Ford, Thomas Edison, Harvey Firestone and John Burroughs reportedly camped at Swallow Falls in August 1918 (the park preserves the campsite they used — a camp at the site is now available to visitors). The park was established by the state in 1906, one of Maryland’s earliest state park acquisitions. The ancient hemlock grove is one of the most significant old-growth forest remnants in Maryland.

Swallow Falls State Park is in the Allegheny Plateau of western Maryland — the plateau surface (underlain by Pennsylvanian-age sandstones and shales) has been cut by the Youghiogheny River and Muddy Creek into dramatic gorges. Muddy Creek Falls drops over a resistant sandstone caprock, creating the 53-foot plunge. The Youghiogheny River gorge is carved into the Plateau, with the resistant sandstones forming the gorge walls. The old-growth hemlocks grow on the sheltered, north-facing gorge slopes. The Allegheny Plateau sandstone, the river incision and the glacially influenced Plateau hydrology created the waterfall and gorge landscape.

Swallow Falls State Park’s old-growth hemlock gorge is a premier birding site — blackburnian warblers (a stunning orange-and-black warbler that nests in tall hemlocks, at or near the southern limit of its range), magnolia warblers, Canada warblers, hermit thrushes (nesting in the cool gorge forest), and other Appalachian-forest birds nest in the park. The Youghiogheny River supports native brook trout, common mergansers, and belted kingfishers. White-tailed deer, black bears and wild turkeys are common in the surrounding highlands. The gorge offers excellent Appalachian forest birding.

Swallow Falls State Park protects one of Maryland’s most significant old-growth forest remnants — ancient eastern hemlocks (some over 300 years old and 3–4 feet in diameter) in a sheltered gorge microclimate that escaped the historical tanning industry. The hemlock woolly adelgid (an invasive pest that has devastated hemlock populations in the East) is a severe threat to these trees; the park monitors the hemlocks and treats the most valuable individuals. Protecting the old-growth hemlocks, the gorge hydrology and the Youghiogheny River water quality sustains this irreplaceable forest remnant.

Swallow Falls State Park holds a treasured place among the natural icons of Maryland — the state’s finest waterfall park, home to Maryland’s highest waterfall (Muddy Creek Falls), an ancient old-growth hemlock gorge, and the camp where Henry Ford and Thomas Edison slept. The combination of dramatic falls, ancient trees and Appalachian gorge scenery makes Swallow Falls exceptional. It is a cherished natural icon of western Maryland and a beloved destination for the Baltimore-Washington region.

Swallow Falls State Park is in Garrett County, about 9 miles northwest of Oakland, MD, on Maple Glade Road off Oakland-Sang Run Road. The park parking area is a short walk from the waterfall trailhead; a Maryland state park fee applies. The park campground (on the same access road) requires advance reservations for summer weekends (recreation.gov). Deep Creek Lake is about 10 miles northeast. Oakland has services. The park is about 2.5 hours from Baltimore and Washington DC. Check Maryland DNR for current fees, campground reservations and conditions before visiting.

Maryland DNR manages Swallow Falls State Park. The hemlock woolly adelgid is the most serious conservation threat — the park monitors the ancient hemlocks and treats the most important trees; visitors help by not spreading the adelgid (do not transport hemlock branches or cuttings from outside the park) and by reporting any signs of adelgid infestation (woolly white masses on hemlock branches) to park staff. Stay on the designated trail loop (the gorge is fragile and off-trail traffic damages the roots of the ancient hemlocks). Pack out all trash; leave no trace. Protecting the old-growth hemlocks is the primary conservation priority.

The gorge trail is rocky and uneven — wear sturdy footwear with good traction (the wet rocks near the falls are slippery). The Muddy Creek Falls observation area has safety barriers, but use caution on the rocks near the base. The trail can be icy in winter (the park may require microspikes in ice conditions — check before visiting). Blackbears are present in the surrounding highlands (practice proper food storage at the campground). Ticks are present; check after hiking. Respect the rocky gorge trail, the slippery falls, the potential for ice in winter and the bears at camp.

Maryland state park entrance fee applies; campground reservations required in summer (recreation.gov or Maryland DNR). Stay on the designated 1.5-mile trail loop. Do not enter the pool at Muddy Creek Falls (dangerous currents and posted). Do not bring hemlock material from other areas (adelgid prevention). Pets on leash. Pack out all trash. Check Maryland DNR for current fees, campground availability and conditions before visiting.

Deep Creek Lake (about 10 miles northeast — Maryland’s largest lake, with summer boating and fall foliage), the Youghiogheny River (below Sang Run, with Class III–IV whitewater rafting for experienced paddlers), the town of Oakland (with services and the Garrett County seat), the Casselman River (Class II, good for beginner paddlers), and the West Virginia border and the Monongahela National Forest to the south define the region. Swallow Falls and Deep Creek Lake together anchor the outdoor experience of western Maryland’s Garrett County, a superb combination — hike the falls in the morning and boat or kayak Deep Creek in the afternoon.

Walk the 1.5-mile loop clockwise (go to Muddy Creek Falls first while you’re freshest — the plunge is the most dramatic sight in the park) and then follow the loop through the Swallow Falls cascade and along the ancient hemlock gorge. Come in spring (April or May) for the fullest falls and the warbler song filling the hemlock gorge — listen for the buzzy, rising song of the blackburnian warbler high in the hemlocks. Visit in winter after heavy snowfall for a hauntingly beautiful, completely uncrowded experience (check for icy trail conditions first). Combine with a Deep Creek Lake afternoon for the perfect western Maryland day.
