The mega-classic Adirondack challenge. First created in the 1920s, it includes New York's 46 Adirondack peaks over 4,000 ft high with at least 300 ft of prominence. Subsequent surveys have found 4 of the peaks to be lower and 1 excluded peak to be higher (MacNaughton, not included in peakery) but the challenge remains unchanged due to tradition. A unique aspect to this challenge is that 20 peaks are "trailless", i.e., without an officially maintained trail to the summit. A 4 hour drive from the heart of NYC and just 2 hours from Montreal.

  • Visit the treasured alpine zones on the tops of the highest peaks in New York: Mt Marcy, Algonquin, Haystack, and more. Remember to always stay on the trails up here to protect the endangered vegetation.
  • Burn some serious calories on a traverse of the Great Range with its steep ups-and-downs and tortured, rocky, rooty footing. So many classic peaks all in a line. Do them all in a day... if you're a little bit insane.
  • Get away from the crowds on any of the 20 peaks without officially maintained trails... just bring some overnight gear just in case you get lost.
  • Summit Mt Colden via the infamous Trap Dike, a steep, rocky Class 3 scramble from Avalanche Lake
