Summary
A free backcountry permit is required (no reservations; first-come, first-served at ranger stations). There are no fees. Campsites are primitive, with pit toilets but no water, fire rings, or picnic tables. Fires are prohibited. RVs are not permitted; access is via a strenuous hike on the Copper Ridge Trail. The alpine lake setting is stunning—crystal-clear water, surrounding peaks, and subalpine meadows. Nearby trails include the Copper Ridge and Whatcom Pass routes. Best visited July–September for snow-free access and wildflowers. Ideal for experienced backpackers seeking solitude and breathtaking scenery.
