Beavertail Hill State Park in Montana, USA - map and visitor information

Research checked: 2026-10-27. Check linked official notices before travel.

Beavertail Hill State Park is a small Clark Fork River campground and nature-trail stop near Clinton, Montana. Cottonwoods shade the self-guided trail, and summer visitors can book an electric campsite or an unfurnished tipi. Winter changes the visit completely: access is on foot for day use, with no overnight camping.

Cottonwoods beside the Clark Fork

• Follow the self-guided nature trail through the cottonwood canopy.
• Use the park as a riverfront picnic stop close to Interstate 90.
• For an overnight stay in season, choose between a conventional campsite and a tipi that requires your own sleeping equipment.

Check the operating season first

Fees, hours, and seasonal access

River access and seasonal services

Boating access is carry-in only. Watercraft entering Montana must meet the inspection and Vessel AIS Prevention Pass requirements stated by the booking provider before launch. Check the park’s current notices before relying on a seasonal restroom or water supply.

Camp quietly and keep pets close

Use designated fire areas, observe any additional fire restrictions, and leave fireworks at home. Quiet hours run from 10 p.m. to 7 a.m. Keep pets supervised and leashed, remove their waste, and follow posted exclusions. Montana’s general maximum leash length is 8 feet unless a stricter rule is posted.

Campsites, tipis, and access needs

Use the authorized Beavertail Hill booking page to choose a unit. Campsite reservations can be made up to three months ahead and at least one day before arrival; a rolling booking window does not extend the operating season. Montana limits camping to seven nights in any 30-day period.

Accessible campsites require an eligible party member to occupy the site throughout the stay and provide the specified disability placard or license-plate proof. Tipis are not ADA accessible. Confirm the particular site’s approach and facilities before reserving.

Arrival from Interstate 90

Take I-90 exit 130, then travel about a quarter-mile south on Bonita Station Road. The entrance address is 29895 Bonita Station Road, Clinton, MT 59825. The official park map helps locate the campground and trail area.

Nearby parks along the Missoula route

• Milltown State Park: a day-use option toward Missoula with Confluence and Gateway entrances. The Milltown Overlook is closed indefinitely because of hillside instability; use the other designated park areas.
• Travelers’ Rest State Park: at Lolo, with an entrance on U.S. 12 west of U.S. 93. The park and visitor center close on Thanksgiving, Christmas Eve, Christmas, and New Year’s Day.

Walk the trail or plan a seasonal stay

The nature trail is the simplest way to experience the riverside cottonwoods without arranging an overnight stay. A picnic can suit a passing visit. For boating, choose equipment you can carry to the water rather than expecting a vehicle launch ramp.

What the campground provides

There are 24 electric campsites and two rental tipis. The tipis have no furniture; a picnic table and fire grill stand outside each. Restrooms, drinking water, and other listed amenities are seasonal, so match your equipment to the actual operating dates.

A compact riverside park

Montana Fish, Wildlife & Parks manages this 65-acre site at an elevation of 3,615 feet. Its scale makes the cottonwood trail and riverfront the focus, rather than a large backcountry trail network.

Riverside habitat

The cottonwood canopy is part of the riverfront setting. Birdwatching and wildlife viewing are listed park activities; watch without expecting a particular species or sighting.
