Richardson Lake Access is a scenic destination reached via a 3-mile 4WD trail from Miller Lake that features dispersed campsites along the shoreline and panoramic views of the Desolation Wilderness.

The trail crosses the Pacific Crest Trail and continues to Sourdough Hill summit, offering excellent vantage points for the surrounding alpine lake region.

Access is seasonal (best in summer and fall) and requires high-clearance vehicles; the trailhead is located just past Miller Lake on the McKinney Rubicon route from the Tahoma Staging Area.
