Experience breathtaking high alpine scenery beneath Longs Peak in Colorado

Nestled in a cirque beneath Longs Peak, Chasm Lake is a magnificent high-altitude destination in Rocky Mountain National Park. Reaching the lake requires a challenging round-trip hike of over eight miles across forested trails, subalpine meadows, and steep rocky slopes. Hikers are rewarded with dramatic views of the iconic Diamond sheer cliff reflecting in pristine alpine waters.

Quick tip: Start your hike before dawn to snag trailhead parking and return before afternoon thunderstorms roll over the mountains.
