No, this loop is generally considered difficult and is best suited for moderately experienced hikers. It features significant elevation changes, rocky and uneven paths, and sections that may require using both hands and feet for climbing and descending. Beginners might find the terrain too challenging.
The terrain is varied and challenging, featuring significant elevation changes, including an approximately 800 ft total gain over 4.2 miles in one section. You'll encounter rocky and uneven paths, ridge runs with jagged tops, and some areas requiring 'hand-over-hand climbing'. A particularly steep section, known as the 'Agony Grind', drops 600 feet over just 0.4 miles. Portions of the trail follow recently rerouted and reblazed paths.
The loop typically starts from the Elk Pen parking lot, which is a large and convenient parking area. Another option is the Anthony Wayne Recreation Area.
Generally, there are no specific hiking permits or entrance fees required to access the trails within Harriman State Park itself. However, parking lots, especially during peak season, might have a fee. Always check the official Harriman State Park website for the most current information regarding parking fees or any temporary regulations.
Yes, dogs are generally allowed on trails in Harriman State Park, including this loop. However, they must be kept on a leash at all times. Be mindful of the challenging terrain, as some sections might be difficult for dogs, especially the steep climbs and descents.
The loop offers beautiful scenery throughout the year, but spring and fall are often considered ideal due to milder temperatures and vibrant foliage. 'Stick season' (late fall/early winter) can also be beautiful for clear views. Summer can be hot and humid, while winter hiking is possible but requires appropriate gear for snow and ice.
This loop offers numerous scenic points. You'll pass by natural features like Bowling Rocks and The Lemon Squeezer. There are also several summits offering panoramic vistas, including Jackie Jones Mountain, Irish Mountain, Pound Swamp Mountain, and Island Pond Mountain. You'll also encounter Lake Skannatati and the Big Hill shelter, with views of the Hudson River, Bear Mountain, and possibly even Manhattan on a clear day.
Yes, the Elk Pen to West Mountain Loop integrates with several other trails. Portions of the route follow sections of the famous Appalachian Trail (marked with white blazes). Other official trails you'll encounter include the Suffern - Bear Mountain Trail, Arden - Surebridge Trail, Red Cross Trail, 1779 Trail, and Dunning Trail.
Be prepared for the challenging 'Agony Grind' descent and sections requiring 'hand-over-hand climbing'. It's highly recommended to bring an updated map, such as those from the NY-NJ Trail Conference, as some trail blazes and routes have been rerouted (including a 2022 AT detour), which can cause confusion with older maps. Starting early is advisable to allow ample time for the difficult sections.
Given the difficult terrain and length, sturdy hiking boots with good ankle support are essential. Bring plenty of water, snacks, a first-aid kit, and an updated trail map. Trekking poles can be helpful for stability on rocky sections. Depending on the season, layers of clothing, rain gear, and sun protection are also recommended.
The Elk Pen trailhead itself is fairly rustic, primarily offering parking. For amenities like cafes, restaurants, or accommodation, you would need to venture a short distance outside of Harriman State Park to nearby towns. It's best to plan for all your needs before arriving at the trailhead.
