White Sandy Campground is a 32-site BLM facility on Hauser Lake's western shore featuring spacious gravel parking pads, a concrete boat launch with courtesy dock, and a sandy beach area—ideal for both boating and fishing access.

The campground offers potable water, vault toilets, fire rings, and picnic tables at each site, with reservations required ($25-$140/night, May-October).

Located 15 miles northeast of Helena, it provides excellent day-use parking and amenities including a fish cleaning station, though note that T-Mobile is the only reliable cell service and water quality can be affected by seasonal algae.
