Allen Mountain

The standard and recommended route to Allen Mountain begins from the Upper Works trailhead, located off New York State Route 28N. Hikers follow the Hanging Spear Falls Trail (also known as the East River Trail) for about 5.1 miles before turning onto a distinct herd path that leads to the summit. This is a very long and strenuous out-and-back hike, approximately 18 to 19 miles roundtrip with about 3,700 feet of elevation gain. Most hikers should plan for a full day, typically 10-14 hours, to complete the ascent and descent.

Allen Mountain is located within the Adirondack High Peaks Wilderness. While specific permits are not generally required for day hiking, hikers must adhere to Leave No Trace principles. Group sizes are limited, and certain regulations apply to camping, campfires, and waste disposal. It's always advisable to check the latest regulations from the New York State Department of Environmental Conservation (DEC) before your trip.

No, Allen Mountain is generally not considered family-friendly or suitable for beginners. It is one of the most challenging and remote hikes in the Adirondacks, known for its significant length, elevation gain, numerous water crossings, and slippery sections. It requires a high level of physical fitness, endurance, and experience with wilderness hiking. There are no beginner routes to the summit.

The primary trailhead for Allen Mountain is at Upper Works, near an abandoned stone furnace. Parking is available here, but it can fill up quickly, especially during peak season and on weekends. Arriving early in the morning is highly recommended to secure a spot, particularly given the long duration of the hike.

Hikers should be prepared for several unique challenges. The trail involves multiple water crossings, including the Hudson and Opalescent Rivers (where a bridge was destroyed in 2019 and has not been replaced). A distinctive feature is the presence of 'red slime' or algae on slippery rock slides and slabs, particularly along Allen Brook during the steep ascent. Traction devices like Microspikes may be useful even in non-winter conditions due to this slipperiness. The final miles involve a significant and steep climb.

Allen Mountain can be hiked in winter, but it presents significantly increased challenges. Winter conditions mean deeper snow, ice, and colder temperatures, requiring specialized gear such as snowshoes, microspikes or crampons, and appropriate cold-weather clothing. While more arduous, winter ascents can sometimes offer unparalleled 360-degree views above the tree line that are not always available in other seasons. Only experienced winter hikers should attempt this peak in colder months.

Yes, dogs are generally permitted on the trails to Allen Mountain, provided they are kept on a leash. Hikers should ensure their dogs are well-behaved, accustomed to long and strenuous hikes, and capable of navigating challenging terrain, including water crossings and slippery sections. Always pack out all pet waste.

Given the length and difficulty, essential packing includes plenty of water (at least 3-4 liters per person), high-energy snacks, a map and compass or GPS device, a headlamp with extra batteries, a first-aid kit, rain gear, extra layers of clothing, and sturdy hiking boots. Traction devices might be useful even in non-winter conditions due to slippery sections. In winter, add snowshoes, microspikes/crampons, and extreme cold-weather gear.

The Upper Works trailhead is quite remote. For accommodations, you might find options in nearby towns like Newcomb or Long Lake, which offer a range of lodging from motels to cabins. Keene Valley, while a bit further, also has various inns and B&Bs. Dining options, including cafes and pubs, are available in towns like Keene Valley and Newcomb, though they may be limited, especially outside of peak season. It's best to plan ahead for meals and lodging.

The standard approach from Upper Works via the Hanging Spear Falls Trail and herd path is the recommended and most common route. Historically, alternative approaches on old lumber roads existed, but these are no longer recommended as they have been 'renaturalized' by the New York State Department of Environmental Conservation. Approaching from the Elk Lake-Marcy Trail or Mount Skylight is also discouraged due to blowdown and thick second-growth forest. There is no recognized loop trail for Allen Mountain; it is an out-and-back hike.

Allen Mountain is one of the 46 Adirondack High Peaks, making it a crucial summit for those aiming to complete the 'Adirondack 46er' challenge. Due to its remote location, significant length, and challenging terrain, it has historically been considered one of the most demanding peaks to complete, often saved by hikers as one of their final ascents to achieve 46er status. Its unique features and the sense of accomplishment it offers contribute to its significance.
