Round Top Lake Access is located at the Woods Lake Trailhead in the Carson Pass Management Area of Eldorado National Forest, accessible via Woods Lake Road off Highway 88 approximately 2 miles south of Carson Pass.

The trailhead offers parking (with a $10 day-use fee as of 2024), restrooms, and serves as the primary access point for reaching Round Top Lake via a moderate 5. 4-mile round-trip hike through the Mokelumne Wilderness.

No day-use permit is required for day hiking, though overnight stays require a free permit, and the optimal hiking season is late June through early October after snowmelt clears the trails.
