Snag Lake Access is located at Juniper Lake's north shore in Lassen Volcanic National Park, accessible via a rough dirt road (13. 4 miles from Highway 36) that is too rough for trailers.

The trailhead features a large parking lot and serves as the starting point for backpacking trips to Snag Lake, Widow Lake, and Jakey Lake, with a moderate 17-mile round trip offering access to multiple alpine lakes in the volcanic wilderness.

A wilderness permit is required for overnight camping, and the area is typically accessible from late June through mid-October.
