- Distance: 3.4 miles roundtrip
- Elevation Gain: 830 feet (253 m)
- Type of Trail: Out & Back
Gem Lake is a hidden gem tucked away in the vast field of granite domes that comprise the Lumpy Ridge area. Without an inlet or outlet stream, Gem Lake is a shallow pond filled in strictly by trapped snowmelt and rainfall.
The Gem Lake trail is accessed via the Lumpy Ridge Trailhead. The relatively low elevation and southern exposure of the Gem Lake Trail make this a great year-round hike.
Make sure to take in the views of Estes Park, Longs Peak, and the Continental Divide that this trail offers you.
