Mon–Wed, Sep 21–23, 2026

BPX Trip – BPX 3-Day: American Lakes from La Poudre Pass TH

A 3-day, 2-night out-and-back backpack from La Poudre Pass Trailhead follows the Grand Ditch Trail to the Thunder Pass Trail, entering Rocky Mountain National Park before crossing into State Forest State Park. Continuing over Thunder Pass, the route descends to establish camp near American Lakes in a remote alpine basin. Day two offers rewarding exploration options to Lulu Mountain, Snow Lake, Nokhu Crags, or The Electrode. We'll return to the TH following the same route over Thunder Pass and along the Grand Ditch.
