  • Mount Massive is the 2nd highest peak in Colorado and the 3rd highest peak in the contiguous United States.
  • Long thought to be the highest 14er in Colorado before next-door neighbor Elbert took that crown.
  • Name comes from its elongated shape with 5 summits over 14,000 ft and a summit ridge over 3 miles long.
  • Has the most acreage above 14,000 feet of any mountain in Colorado.
  • Standard route starts on the Colorado Trail before an often gradual ascent through wide alpine meadows to the summit ridge.
"Beautiful day with cooperative weather and friendly hikers. We stayed on the summit for about 45 minutes enjoying lunch and the other hikers. Massive, she's a steep one. Gorgeous hike. We saw a goat!" - wendyglitterhippie, Aug 25, 2018
"Climbed the steep route up from the South / South West (half-moon Camp) and took the gradual route down to the main trail head for mount Massive.

"Great day in the mountains. Easy to lose the trail in snow over 13k and wound up going up some loose talus. Conditions were perfect for glissading on the descent- 3800' in only 2 hours!" - Christopher, Jun 11, 2017
"My second summit of Mount Massive! This was my first time climbing it via the East Ridge. Not an easy route! It is about the same distance as the standard route, but with more elevation gain. You can see the standard route just a few miles south while on this route. The last 3 miles up the ridge are by far the worst! There are tons of ups and downs on the ridge, and because of the snow there were some places that were class 3. Also, everyone should know that the bears are starting to wake up and become active for the season. We broke trail on the way up. On the way down there were huge bear tr" - IanWright, Apr 13, 2016
