Hiking to Chasm Lake offers many rewards. The trail is excellent and very scenic. Before the final trail fork, you are likely to encounter hikers trying to summit nearby Longs Peak.  At Chasm Lake, the view of the massive east face of Longs -- called "The Diamond" -- is awe inspiring, rising 2,400' above the lake.  Climbers going up the Diamond can usually be seen. Much of the shoreline around the lake is accessible, however, some minor rock scrambling is required to reach the final destination

This hike will last most of the day.

  • This is an on-trial hike most of the way to Chasm Lake. There will be some scrambling as we approach the lake.

  • All hikers must have all 10 Essentials, or "your" 10 Essentials.  Be prepared for cold, windy weather at Chasm Lake.  Gloves, hats and wind layers recommended. Poles for the descent are optional. 

  • We may add a little mileage to the trip if we have to park down the road. This is the main TH for Long's Peak where most hikers get a ~2am start so the main parking lot fills up quickly. 

  • There are pit toilet bathrooms at the TH. 

  • A parks pass is NOT needed for this entrance. 

  • Approximate hiking time: 6.5hrs (may be quicker depending on group pace) 

  • Approximate timeline: 7:00am leave TH, 10:30am arrive at Chasm, 30min break at Chasm, return to TH at 1:30, back to Boulder by 3:00pm

  • **Email trip leaders for signup passcode. In the email, let us know the last time you went on a comparable trip**
