Hike to Chasm Lake

Colorado Longs Peak Trailhead

Added by Kyle Frost

  • Get the classic sunrise shot on Longs Peak
  • A fantastic (relatively) short hike with sublime views
  • 9 mile roundtrip hike with 2500' elevation gain
  • Option to summit Longs Peak (14255') if you've got the energy

The 4.5 mile trail climbs around 2500ft from the Longs Peak trailhead, and starts by winding through dense forest. In the morning darkness, trudging through thick trees isn’t the most exciting, but when you finally climb out above treeline, the massive profile of Longs and the slowly growing light on the horizon is a welcome sight.

Make sure you know your hiking speed and leave early enough to arrive at the lake for the classic 'Sunrise hitting Longs Peak' shot! If you've got energy to spare after taking in the sunrise, backtrack a little back to East Longs Peak Trail and head up to the peak through the Keyhole route. This will tack on another 5.5 miles and add an additional 2500' in elevation, so make sure you're ready!

How to Get There

Everyone Should Go.

Honestly, this is the only hike that I have done inside of RMNP, but it was AMAZING. It is a perfect balance of hiking through forests, alpine tundra, (we had some snowfields near the lake), and a phenomenal view of Chasm Lake at the top! Take a plunge if you are truly daring... IT'S WORTH IT.

Chasm Lake Hike

This is one of my favorite hikes I've ever done. Just wanted to add that if anyone wants to shorten their morning hike there is a backcountry campsite along the Longs Peak trail. Goblin's Forest is located 1.1 miles from the trailhead. Although shaving off only a mile from the hike doesn't seem like much it was also convenient to not have to worry about driving in and finding a parking spot in the overflowing parking lot. All in all I would highly recommend this adventure!

Hard for a Georgian

The view was worth it, but 11,000 ft and a 2500 ft climb from the trailhead made this quite the challenge for me and my wife. We aren't in GREAT shape, but we do enjoy hiking in and around Atlanta. Over hydrate before this hike if you live in the flatlands like me!
