Chasm Lake is one of the most popular hikes in Rocky Mountain National Park for a reason.
Starting from the Longs Peak Trailhead this trail takes you up to an amazing alpine lake underneath Mt. Meeker, Longs, and Lady Washington. Start early though because the parking fills up extremely fast with people getting an early jump on the Keyhole route to Longs.
