- Elevation: 5,114 feet
- Elevation gain: 2,936 feet

Leave Lake Placid on Route 73, follow Route 73 toward Keene. Take you first right after the ski jumps onto Adirondack Loj Road. Follow this road to its end and park at the hiker trailhead. There is a fee to park here in this lot, and it is often full on summer days, so get there early.
Algonquin in winter
Algonquin is a challenging mountain that should only be attempted by experienced hikers, especially in winter. Snowshoes are a must for much of the route, and snow spikes or crampons are necessary to climb the exposed upper reaches of the peak. Plan on the temperature in the higher elevations being at least 20 degrees colder than in the valley, not including the windchill. Bring several extra non-cotton layers, a headlamp with spare batteries, extra food, and supplies for spending the night in case of emergency.
This 4.3 mile hike starts along the popular trail that leads to the former site of Marcy Dam. The path traverses rolling terrain to an intersection at the 1 mile point. Continue straight to head up Algonquin. The path gets steadily steeper and reaches an impressive waterfall at 2.6 miles.
After two steep, rocky sections the path levels out, then it makes a sharp left at 3.1 miles, where a sign warns hikers about rapidly changing weather conditions above timberline. Heed the warning — from this point on much of the trail is open and exposed to the elements.
Shortly after the sign the intersection with the trail up Wright Peak’s summit is reached at 3.4 miles. Continuing straight, the path up Algonquin’s summit cone varies from steep to very steep as it approaches tree line, after which it is completely open as it steeply approaches the summit at 4.3 miles.
The trail continues over the top of Algonquin, following the mostly open ridge to Boundary and Iroquois mountains, the latter of which it reaches in 1.1 miles. The view from Iroquois is especially striking — Algonquin’s rocky crown towers above it and the striking 1,000-foot cliff on Wallace mountain rises from Indian Pass below.
A loop option that includes a return through Avalanche Pass is also possible by taking the path to Lake Colden from the col between Algonquin and Boundary peaks, then turning left toward the pass. This is an extremely steep, rugged trail that will add significant time to the hike, so plan accordingly.
