Backpacker's Walk-In Campground is a primitive, tent-only campground at the east end of Lake Alpine designed for backpackers preparing for early morning treks into the Sierra Nevada backcountry.

The 8-site facility offers a one-night maximum stay with basic amenities (flush toilets, picnic tables, fire rings) but no water or RV access, making it an ideal staging area for backpacking expeditions rather than extended camping.
