About Tourmaline Lake
Tourmaline Lake has its own place in the Moraine Park / Cub Creek landscape: a hard lake at 10,588 feet. It sits on the east side of the Continental Divide.
The setting is remote, near Odessa Lake area. The approach from Fern Lake TH is 5.5 miles one-way and belongs in the hard tier for this guide. Moraine Park and Cub Creek offer lower-elevation water, meadow, forest, and links into the Fern Lake system. The distance and setting make this a plan-ahead destination, not a casual lake stop.
NPS hiking tables list Cub Lake and Fern Lake as east-side hikes from different trailheads, and the trail system between them helps make this area more connected than a single out-and-back.
🚫 No restroom at the Fern Lake TH trailhead — plan accordingly. Restrooms are available at the Moraine Park Complex lot, approx. 0.5 miles before this trailhead.
