Fourmile Lake Campground Boat Ramp provides access to a pristine alpine lake at 5,744 feet elevation with a rustic Forest Service campground featuring 29 campsites, horse corrals, vault toilets, and hand-pumped water.

The boat ramp and day-use area offer parking for boat trailers and vehicles, making it an ideal launch point for kayaking, canoeing, and fishing.

Located at the southern end of Sky Lakes Wilderness with trailheads for backpacking into the wilderness, the campground is open seasonally (typically July through early September) and operates on a first-come, first-served basis with day-use and overnight fees.
