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

"Second (and technically Third as we climbed over on the way back) time up here. Headed out to Iroquois to get #17/46. Algonquin is such a beautiful summit, I had no problem doing it again. We took our good friend Roger with us for his first 5,000er and along with Iroquois, his 5th and 6th High peaks." - Algonquin Peak, UK-Ranger, Sep 7, 2018
"Dense Fog th2 whole day so no views. Beautiful climb through Gil Brook and it felt like Jurassic Park. When with Mark and Paul and also did Blake Peak. Round trip was 9 hours. " - Mount Colvin, heyjudeee, Sep 1, 2018
"We set out early (leaving home at 5h00am and arriving at 7h00am) to do both Mount Colvin and Blake Peak. Upon walking on Lake road, we realized that this would be the last time we would use this Trailhead since we have done all the peaks that start from it. The ascension of Colvin was tough. There was a lot of mud and slippery rock. There was a point were we also miss a marker (an arrow painted on a rock). We took a left instead of a right. After 5 minutes we realized that we were not on a trail. We went back and finally noticed the "Arrow" on the rock. On the summit of Colvin we met a lot" - Blake Peak, CPaquin, Aug 23, 2018
