Mount Marcy | Adirondacks

Mount Marcy is the tallest mountain in New York State, reaching an elevation of 5,344 feet (1,629 meters). Located in the High Peaks Wilderness Area of Adirondack Park, it is a premier destination for hikers and outdoor enthusiasts and offers panoramic views of the surrounding mountains, lakes, and forests. It is also part of the revered group of Adirondack High Peaks, often pursued by those completing the 46er challenge.

Location and Overview

Mount Marcy lies in Essex County and is accessible from several trailheads, the most popular being from the Adirondack Loj near Lake Placid. The mountain was named after Governor William L. Marcy, who authorized the first geological survey of the Adirondacks in the 1830s. It is known by the Mohawk people as “Tahawus,” meaning “Cloud-Splitter,” which refers to its frequent mist-covered summit.

Hiking Routes

The most common route to Mount Marcy's summit is the Van Hoevenberg Trail:

Starting Point: Adirondack Loj at Heart Lake

Round-trip Distance: Approximately 14.8 miles (23.8 kilometers)

Elevation Gain: Around 3,100 feet

Estimated Time: 7 to 11 hours depending on pace and conditions

Difficulty: Strenuous

The trail is well-maintained and clearly marked, ascending through forests, wetlands, and open rock slabs near the summit. It offers diverse scenery and leads through boreal forest before transitioning to alpine vegetation at higher elevations.

Alternate trails include:

From Upper Works via the Calamity Brook Trail (more remote, about 18 miles round-trip)

From Johns Brook Lodge via the Phelps Trail (can be done as a multi-day trip)

What to Expect

The hike to Mount Marcy is long and demanding but not technical. The final ascent includes rocky terrain and open alpine exposure, especially in the last mile. The summit provides sweeping views of nearby peaks such as Mount Haystack, Skylight, Basin, and Colden. On exceptionally clear days, distant peaks in Vermont and even Canada may be visible.

The area above the tree line is ecologically sensitive, hosting rare alpine plants and mosses. Hikers are strongly encouraged to remain on marked paths to avoid damaging these fragile ecosystems.

Seasonal Considerations

Summer and fall are the most popular times to hike. Fall foliage typically peaks in late September or early October.

Winter ascents are common among experienced hikers and backcountry skiers, but conditions are harsh, with ice, wind, and deep snow.

Spring (late April through early June) is generally considered mud season, and trails can be wet, slippery, and prone to erosion.

Preparation and Safety

Start early in the day to allow time for a safe return before dark.

Bring adequate food, water, and layers of clothing, including rain and wind protection.

Navigation tools like a map, compass, or GPS are recommended.

Bear canisters are often required in this area for overnight trips.

Wilderness camping regulations must be followed; campsites must be at least 150 feet from trails and water bodies.

Nearby Peaks and Side Trips

Ambitious hikers may combine Mount Marcy with nearby peaks:

Mount Skylight (4,926 feet) – Known for its 360-degree views and wide summit

Mount Haystack (4,960 feet) – Considered one of the most scenic Adirondack peaks

Gray Peak (4,840 feet) – A trailless but accessible summit from the Four Corners area

These combinations are typically done as overnight hikes or very long day hikes.

Lodging and Facilities

Adirondack Loj offers trailhead parking, lodging, and tent sites. Reservations are recommended in peak seasons.

Johns Brook Lodge, located deeper in the wilderness and operated by the Adirondack Mountain Club, provides meals and bunks for those hiking from Keene Valley.

Lean-tos and primitive campsites are available along the trails with adherence to regulations.

Summary

Mount Marcy is not only the highest point in New York but also a symbolic heart of the Adirondack wilderness. Its summit rewards hikers with vast, open views and a sense of accomplishment. With proper planning, gear, and respect for the environment, a hike up Mount Marcy is one of the most rewarding experiences in the Northeast.
