Big Larch Campground offers 50 individual campsites across four loops plus group sites on Seeley Lake's east shoreline, featuring a concrete boat launch, boat trailer parking, and a roped-off swimming beach for day-use access.

The campground provides ample shade in a mixed conifer forest at 4,000 feet elevation, with water, toilets, and campground hosts available; loops 1 and 4 operate year-round while loops 2-3 are seasonal (Memorial Day through Labor Day).

Located just 1 mile north of Seeley Lake town on Highway 83, it serves as an excellent base for paddling the nearby Clearwater Canoe Trail and accessing the Chain of Lakes.
