Mount Marcy ranks No. 58 among the Lower 48 Top 100 prominence peaks in the Prominence Registry, rising 5,345 feet in the Adirondack Mountains of New York with 4,917 feet of clean prominence. It is the highest point in New York and the dominant summit of the Adirondack High Peaks within the High Peaks Wilderness of Adirondack Park. Most hikers use the Van Hoevenberg Trail for 14.8 miles round-trip with 3,166 feet of gain on Class 1 terrain; no day-hiking permit is required, but paid parking applies at Adirondak Loj.

ListsOfJohn gives Mount Marcy a LiDAR-based prominence of 4,917 feet, just 83 feet below the 5,000-foot threshold used for ultra-prominent peaks. Together with 129.93 miles of isolation from higher ground, that figure makes Marcy one of the most topographically independent summits in the northeastern United States.

The mountain is composed primarily of anorthosite, a coarse-grained igneous rock associated with the Grenville Orogeny roughly 1.1 billion years ago. Pleistocene glaciation carved the surrounding High Peaks landscape, depositing erratic boulders and shaping the valley systems that define the region. On the southwest shoulder at 4,293 feet sits Lake Tear of the Clouds, widely cited as the highest source of the Hudson River. The summit supports a rare alpine plant community, one of the southernmost intact high-elevation ecosystems in the eastern United States. Ebenezer Emmons led the first recorded ascent on August 5, 1837, during a New York State geological survey, and named the peak for Governor William L. Marcy, who commissioned the work.

Recommended Route

Van Hoevenberg Trail

The standard route runs 7.4 miles one way from Adirondak Loj at approximately 2,170 feet, gaining about 3,166 feet of net elevation to the summit, with cumulative gain often measured higher by GPS. The first 2.1 miles are the least demanding section, following well-used trail through spruce-fir forest to Marcy Dam at approximately 2,350 feet. The route then climbs through increasingly rocky terrain past Phelps Brook and Indian Falls at approximately 3,700 feet, where the footing transitions to rough, wet rock and root systems. Above Indian Falls, several trail junctions require navigation attention, particularly on descent. The upper mountain climbs toward the alpine zone, with treeline reached at approximately 6.8 miles; from there cairns and rock blazes mark the route across exposed bedrock to the broad summit cone. The round trip is typically completed in 7 to 10 hours.

Other established approaches include the Phelps Trail from the Garden in Keene Valley (9.1 miles to summit), the Calamity Brook Trail from Upper Works (10.3 miles), and the Elk Lake-Marcy Trail (11.0 miles, crossing private land, closed during big-game hunting season).

Key Landmarks

Marcy Dam (approximately 2,350 ft, 2.1 miles from Adirondak Loj) — lean-tos, primitive campsites, water access
Indian Falls (approximately 3,700 ft, ~4.5 miles) — commonly treated as the last dependable water stop before the upper mountain
Summit cone / alpine zone — final approach becomes exposed, with cairns and rock blazes across open bedrock

warning

Afternoon thunderstorms are common on the exposed summit cone from June through August. Parties above treeline when storms develop should descend immediately; the open summit area offers no shelter. On descent, stay on or near the ridge, keep Fourmile Lake visible to the northeast, and follow cairns and markers back to treeline; do not follow the south-facing slope off-route.

Permits & Camping

Climbing Permits

No day-hiking permit is required for the Van Hoevenberg Trail. Parking at Adirondak Loj / the High Peaks Information Center is managed by the Adirondack Mountain Club and costs $18 per day for non-members arriving before 1 p.m., $10 for a half-day after 1 p.m.; ADK members pay lower rates. The lot fills early on summer weekends. No sleeping in vehicles is permitted, and no roadside parking is allowed on Adirondak Loj Road between the booth and Meadows Lane. Verify current rates at adk.org before departure.

Camping & Wilderness

In the Central Zone of the High Peaks Wilderness, campfires are prohibited, bear-resistant canisters are required for all overnight campers between April 1 and November 30, dogs must be leashed, and overnight groups are limited to 8 people. Camping is prohibited on summits and above 3,500 feet except at lean-tos. At-large camping below 3,500 feet must be at least 150 feet from roads, trails, and water. Lean-tos are first-come, first-served and cannot be reserved. Marcy Dam has lean-tos and designated tent sites; verify current site availability and any closures with NYSDEC or the ADK conditions report before departure.

Trailhead: N 44.1830° W 73.9638° (Adirondak Loj, Adirondak Loj Road, North Elba, NY). Elevation 5,345 ft; prominence 4,917 ft (ListsOfJohn LiDAR). Net gain 3,166 ft (Loj ~2,170 ft to summit); cumulative GPS gain commonly 3,500–3,600 ft. Parking fee confirmed $18/day non-members before 1 p.m. per ADK (May 2025); verify current rates. Central Zone is current NYSDEC terminology for this wilderness area.

Wildlife & Seasonal Conditions

The Van Hoevenberg Trail is a non-technical, strenuous day hike on maintained trail with no scrambling, roped climbing, or technical snow travel in normal summer conditions. Descent fatigue on rough, rooted, and wet footing over 14.8 miles round trip is a common issue. Ice and hard snow on exposed rock slabs during shoulder season may require microspikes. Parking congestion at Adirondak Loj on summer weekends can affect turnaround time; arriving late reduces margin for a same-day summit.
