Algonquin Peak is a mountain in the Macintyre Range of the Adirondack in the U.S. state of New York. It is the second-highest mountain in New York, with an elevation of 5,115 feet (1,559 m). It is located in the town of North Elba in Essex County and in the High Peaks Wilderness Area of Adirondack Park. The first recorded ascent of the mountain was made on August 8, 1837, by a party led by New York state geologist Ebenezer Emmons.

Algonquin Peak is the state’s 2nd highest mountain. It is a steep, strenuous hike for much of its length. A successful summit requires physical fitness, research of the trail, correct gear, and knowledge of Leave no Trace principles. An area of 23.5 acres (9.5 ha) surrounding the summit is an alpine tundra zone, the largest found in the Adirondacks.This area is home to many arctic plants, including American dwarf birch, bearberry willow, black crowberry, Bog bilberry and Lapland rose.
