This route combines sections of several trails within Harriman State Park. While specific starting points can vary depending on your chosen access, the Ramapo-Dunderberg Trail portion is notably accessible from the Tuxedo Train Station, making it convenient for those using public transport. For parking, various trailheads within Harriman State Park offer parking, but it's advisable to check specific park regulations and parking availability, especially during peak seasons.
Yes, Harriman State Park generally allows dogs on trails, including sections of the Appalachian, Ramapo-Dunderberg, Dunning, and Arden-Surebridge Trails. However, dogs must always be kept on a leash. Please remember to pack out all waste to keep the park clean for everyone.
The best time to hike this route is typically in the spring or fall. Spring offers blooming flora, while autumn provides spectacular fall foliage, especially in the dense hardwood forests of Harriman State Park. Summer can be pleasant but may involve more heat, humidity, and bugs. Winter hiking is possible but requires appropriate gear for snow and ice conditions.
Generally, there are no entrance fees or permits required for day hiking on the trails within Harriman State Park. However, fees may apply for parking at certain lots or for specific facilities within the park. Always check the official Harriman State Park website for the most current information before your visit.
The terrain on this combined route is quite varied and can be challenging. You'll encounter everything from sections of old mining roads on the Dunning Trail (which are relatively easy) to significant rock scrambles and large rock slabs on the Appalachian and Ramapo-Dunderberg Trails. Expect constant 'up and down' topography, intricate tangles of roots, and potentially muddy bog boards. Some sections will require scrambling over boulders, demanding good physical conditioning.
This route offers several notable natural features and viewpoints. You'll pass by the famous The Lemon Squeezer, a narrow natural tunnel between giant boulders. Other highlights include summits like Island Pond Mountain and Hogencamp Mountain, offering great views. You might also encounter Times Square (a natural monument, not the NYC one!) and lovely bald rocks, especially along the Dunning Trail.
Yes, this route is a combination of several trails and intersects with many others within Harriman State Park. Specifically, the route also passes through sections of the Arden - Surebridge Trail, the Dunning Trail, the Ramapo Dunderberg Trail, the White Bar Trail, and the Bottlecap Trail. This extensive network allows for various loop options and connections to other parts of the park.
Given its moderate difficulty, significant elevation changes, and sections requiring rock scrambling, this particular combined route is generally not recommended for absolute beginners. While parts of the Dunning Trail might be easier, the overall experience, especially on the Appalachian and Ramapo-Dunderberg sections, demands a good level of physical fitness and some hiking experience. Beginners might prefer shorter, less strenuous loops within Harriman State Park.
For a day hike on this route, you should pack essentials like plenty of water (there's no guaranteed water source on the trail), snacks, a first-aid kit, a map and compass (or a reliable GPS device like komoot), appropriate hiking footwear with good ankle support, and layers of clothing suitable for changing weather conditions. Given the rocky terrain, gloves can be useful for scrambling, and trekking poles can aid stability.
One specific challenge is the constant 'up and down' nature, particularly on the Ramapo-Dunderberg and Appalachian Trail sections, which can be very taxing. An insider tip for navigating the more challenging sections, like the The Lemon Squeezer, is to be prepared for some tight squeezes and hand-over-foot climbing. Also, be aware that cell service can be spotty in Harriman State Park, so downloading offline maps is highly recommended. Starting early is also a good strategy to ensure you have ample daylight to complete the hike, especially given its length and varied terrain.
