This route was planned by komoot.
The Komoot route for the LetterRock Mountain Loop Trail is approximately 10.5 km (6.5 miles) long and generally takes around 3 hours and 5 minutes to complete. Keep in mind that individual hiking times can vary based on fitness level, pace, and how often you stop to enjoy the views.
The Komoot route is rated as moderate. However, some variations, like the Black Mountain - Letterrock Mountain Loop, are considered difficult due to significant climbs and rocky terrain. While not ideal for absolute beginners, hikers with some experience and a reasonable fitness level should find the Komoot route manageable. Be prepared for varied terrain and elevation changes.
The terrain primarily consists of rocky forests, characteristic of Harriman State Park. You can expect a good climb to reach viewpoints, and the path may include sections of established trails like the Appalachian Trail and Ramapo-Dunderberg Trail. It offers a varied experience with both ascents and descents.
The trail offers excellent views, especially from the ridges and the summit of Black Mountain, providing expansive south-facing perspectives of Silver Mine Lake and the surrounding area. You'll also pass by other notable points like the Stone Lean-to Shelter, William Brien Memorial Shelter, and a Creek Bridge.
Specific parking information for this exact Komoot route is not provided, but as the trail is primarily within Harriman State Park, you would typically look for designated parking areas near trailheads within the park. It's advisable to check the Harriman State Park website or local trail maps for the most current parking locations and regulations before your visit.
The LetterRock Mountain Loop Trail is located within Harriman State Park. Generally, there are no entrance fees for hiking in Harriman State Park itself, but some parking areas or specific facilities might have fees, especially during peak seasons. Always check the official New York State Parks website for the latest information on fees and regulations before your trip.
Harriman State Park generally allows dogs on trails, but they must be kept on a leash at all times. Please ensure you clean up after your pet and follow all park regulations regarding animals to ensure a pleasant experience for everyone.
The trail can be enjoyed during most seasons. Spring offers lush greenery and wildflowers, while autumn provides spectacular fall foliage, making it a very popular time. Summer is also great, but be prepared for warmer temperatures and potential humidity. Winter hiking is possible for experienced hikers with appropriate gear, but conditions can be challenging with snow and ice.
Yes, the route incorporates sections of several other trails. You will hike along parts of the Menomine Trail, the Red Cross Trail, the Ramapo Dunderberg Trail, the Beech Trail, and even a segment of the iconic Appalachian Trail.
While the Komoot route is a great option, it's worth noting that other variations exist. For instance, the Black Mountain - Letterrock Mountain Loop is a popular, more challenging option known for its excellent views. However, another variation, the Red Cross - Letterrock Mountain Loop, is generally not recommended due to a lack of views and overgrown sections, despite passing through a quiet rhododendron forest.
