Black Sandy State Park

This popular campground provides access for boating, water-skiing, walleye and trout fishing, and other water activities.

About the Park

*As a result of a bank stabilization project, tent sites T-2, T-3, and T-4 will be closed for several months to allow grass to re-establish. 


Come, visit and enjoy one of the few public parks on the shores of Hauser Reservoir. Black Sandy State Park is an extremely popular weekend boating, fishing, camping and water skiing location. 

Boating, fishing, swimming, camping (electrical hookups are available May 1- November 30), picnicking, bicycling, and mountain biking are available. 

Black Sandy State Park has 29 campsites with electricity and one tent site that can be reserved, and 5 tent sites without electricity that are first come-first served. Maximum trailer length is 35 ft. You can make reservations up to one day in advance of your arrival date. For same-day availability, try the park office—406-458-3221—to check if any sites are available for that night. There are also boat slips for rent on a first-come, first-served basis. 

There is NO lifeguard on duty at Black Sandy State Park.

The park is 43 acres at an elevation of 3,835 feet.

Aquatic Invasive Species

Help protect Montana's waters

AIS can be easily spread from one waterbody to the other. Anglers, boaters, construction workers, pond owners, gardeners, seaplane pilots, field workers - virtually anyone who works or plays in or around water can unknowingly transport these pests on their boats and equipment. It takes only one mistake to potentially infest a new water body.

Prevent the spread of AIS
