290 Campers Point, PO Box 8, Decker, Montana, 59025, United States
Boat-and-camp trips are the sweet spot here. Waterfront sites at Sand Point and Campers Point fill fast on holiday weekends, so book early; weekdays have real breathing room. The marina sells bait, propane, and ice, so you don't need a supply run.
No showers anywhere on the property, and the sparse tree cover means brutal midday sun without an awning. Anglers chasing reliable catches will likely be disappointed, and winter drops electric hookups to just 11 sites across the whole park.
Compare with similar sites, watch availability, and build a packing list — Camp Sage handles all of it.
