About
Big Larch Campground occupies a prime location on the east shoreline of Seeley Lake within the Lolo National Forest. The 1,025-acre glacial lake is part of Montana's Chain of Lakes through which the Clearwater River flows. At roughly 4,000 feet elevation, summer temperatures remain pleasant, and the mixed conifer forest of larch and pine provides ample shade, though minimal understory limits site privacy. The campground offers diverse recreation opportunities including a roped swimming beach, concrete boat launch with trailer parking, and an interpretive nature trail. Anglers target kokanee salmon, bass, northern pike, whitefish, and several trout species. The nearby Clearwater Canoe Trail provides 3.5 miles of flatwater paddling through wildlife habitat, while Morrell Falls National Recreation Trail offers an excellent day hike to a large waterfall. Wildlife is abundant, including white-tailed deer, elk, moose, and both grizzly and black bears. Food storage in locked vehicles or bear-resistant containers is mandatory. The town of Seeley Lake is just a mile south, offering boat rentals, guide services, groceries, gas, and restaurants.
