Aspen Grove is a tent-only campground with 28 sites (18 reservable, 10 first-come first-served) located on Eagle Lake's south shore in Lassen National Forest, featuring direct lake access and a nearby swim area at Gallatin Beach.

The campground provides flush toilets, potable water, and picnic tables at each site, with wheelbarrows available to transport gear from the parking area; the adjacent Eagle Lake Marina (10-minute walk) offers gas, propane, fishing and camping supplies, plus shower and laundry facilities.

A 5. 2-mile paved trail connects the campground to five total campgrounds, three day-use areas, and the marina, making it ideal for paddlers and anglers accessing California's second or third largest natural lake.
