Big McGee Lake Access provides trailhead parking with a paved lot, bear boxes, and vault toilets for accessing McGee Creek Trail in the John Muir Wilderness. The trail gains approximately 2,600 feet over 6.

8 miles to reach Big McGee Lake (10,479 ft), with multiple creek crossings including log bridges and potential ford sections that can be challenging during high water.

Camping at the lake is limited to exposed sites on a rocky peninsula, though alternative camping exists in nearby meadows to the west.
