The landscape

Bear Mountain stands on the west bank of the Hudson River where the river cuts through the Hudson Highlands, a band of old, hard rock. The park takes in Bear Mountain itself, Dunderberg Mountain and West Mountain: steep, forested ridges with bare granite ledges on top and views down to the river and the Bear Mountain Bridge. Hessian Lake lies at the foot of the mountain beside the Inn, and Iona Island, a bird sanctuary, sits in the river just offshore.

The land was saved in 1909 and 1910, when a state plan to build a prison here was dropped and private donors gave land and money for a park. Harriman State Park, far larger, adjoins it to the west, and the two share a trail network. The first section of the Appalachian Trail was built here in 1923. The trail still crosses the summit, drops to Hessian Lake, and passes through the Trailside Museums and Zoo, where it reaches the lowest point of its whole length before crossing the bridge.

Best time to go

The park is open all year. Spring and fall are the best hiking seasons, and fall colour in October draws the largest crowds: on fine weekends the parking lots fill by late morning and the park closes to arriving cars until space opens, so come early or on a weekday. Summer is hot and humid on the climbs. Perkins Memorial Drive and the summit tower are open from April to late November, weather permitting, and in winter the summit is reached only on foot. The outdoor ice rink runs from late October to mid-March, and the trails are used for snowshoeing and cross-country skiing when there is snow.

Getting there and around

The Palisades Interstate Parkway runs north from the George Washington Bridge to the Bear Mountain Circle, where it meets US Routes 9W and 6 at the park entrance. Parking is beside the Bear Mountain Inn and Hessian Lake, and most trails start within a few minutes’ walk. From April to November you can also drive Perkins Memorial Drive to the summit. Roadside parking is not allowed, and cars left on the shoulder are ticketed and towed. Buses from New York City stop at the Inn, and the Metro-North station at Peekskill is across the river, a taxi ride away.

Things to do

The classic hike is the loop over the summit: up the Major Welch Trail, which climbs steeply over open rock slabs on the north side, and down the Appalachian Trail, where trail crews have set hundreds of granite steps into the east face. The round trip is about 4 miles (6.4 km) with roughly 1,100 feet (335 m) of climbing. On top, the Perkins Memorial Tower looks over the Highlands and, on a clear day, to the Manhattan skyline about 40 miles (64 km) south. The paved path around Hessian Lake, about 1.5 miles (2.4 km), is an easy, level walk.

The Trailside Museums and Zoo, on the site of Fort Clinton, keeps injured and rescued native animals, including black bears, and has small museums of local history, geology and nature; the Appalachian Trail runs straight through it. Longer routes head west into Harriman State Park or south over West Mountain and Dunderberg Mountain, where the Suffern-Bear Mountain Trail and others cross rougher, quieter ground. The park also has a swimming pool in summer, rowboats on Hessian Lake, a merry-go-round, picnic groves and fishing in the lake and the river.

Staying safe

These are short mountains with steep trails. The Major Welch Trail crosses smooth rock slabs that are treacherous when wet or icy, and the stone steps on the Appalachian Trail are hard on the knees coming down. Wear shoes with good grip, carry water, and allow more time than the distance suggests. In winter the slabs and steps hold ice, so bring traction devices or stay on the lake path. Trails are marked with painted blazes, and several cross one another near the Inn; carry the trail map so you leave the summit on the trail you meant to.

Check for ticks after every hike, since deer ticks in the Hudson Valley carry Lyme disease. Timber rattlesnakes and copperheads live on the rocky ledges and are rarely seen; watch where you put your hands and feet and leave any snake alone. Black bears live in the park, so do not leave food unattended. The park closes at dusk, and hikers who start late are often caught by darkness on the descent, so carry a light.

Know before you go

Dogs are allowed on the trails on a leash of 6 feet (1.8 m) or less, but not in buildings, picnic areas or the Trailside Museums and Zoo, so through-hikers with dogs use a signed bypass. There is no camping in Bear Mountain State Park; backpackers use the shelters in Harriman State Park. This page is a general overview, not a live conditions report, so check for trail closures and detours, parking status and the hours of the tower, zoo, pool and rink with New York State Parks before you go.
