Campgrounds and RV parks near East Helena, MT

East Helena sits just east of Helena in west-central Montana, within easy reach of the Missouri River reservoirs that anchor camping in the region. RV travellers typically base here to access Hauser Lake to the north, Canyon Ferry Reservoir to the east, and the mountain corridors leading toward the Continental Divide. Hauser and Canyon Ferry together provide long shorelines for fishing, boating and lakeside camping, with species including rainbow trout, perch and walleye. Close-in options run from full-service private parks to lakeside state and federal campgrounds. Alhambra RV Park and Helena North KOA Journey serve travellers who want hookups, showers and easy highway access, while Black Sandy State Park is a popular boating, fishing, camping and water skiing location on Hauser Reservoir. Grey Sandy Campground sits on the same lake system, and Townsend / Canyon Ferry Lake KOA Journey covers the south end of Canyon Ferry. Helena itself supplies groceries, propane, fuel, urgent care and RV service, so restocking mid-trip is straightforward.

Booking channels vary by land manager. Black Sandy State Park has 29 electric sites and one tent site that can be reserved, plus first-come, first-served tent sites, with reservations accepted up to one day in advance. Montana State Parks bookings run through the state's ReserveAmerica-powered portal. Canyon Ferry reservations for camping and group-use shelters are made at recreation.gov or by calling 1-877-444-6777, and can be made up to six months prior to arrival, but not less than one day out. Campsites that are not reserved remain available on a first-come, first-served basis.
