Burt Canyon Trail offers a full-day hiking trek between Bridgeport and Walker, Ca. that parallels the Little Walker River. Aspens, Jeffrey pines and juniper trees provide shade as hikers climb a challenging 6.5 miles to Anna Lake, which at 10,500 feet elevation may be icy or even frozen in spring and summer. Wildflowers bloom in plentiful supply here. The trailhead is located west past Obsidian Campground, off Little Walker Road.
