The Blackfoot River, sometimes referred to as the Big Blackfoot River, is a snow-fed and spring-fed river that begins near the town of Lincoln, Montana and flows nearly 130 miles to where it flows into the Clark Fork River just outside of Missoula. The Blackfoot River is one of Montana's most popular rivers.

The Blackfoot River offers a diversity of recreational experiences, including whitewater rafting, kayaking, tubing, fishing, canoeing, and camping. The Blackfoot River flows through a variety of landscapes including open farmlands, tall cliffs, and thick forested slopes. Wildlife is plentiful on the Blackfoot River, where it is not uncommon to see elk, grizzly bears, river otters, bald eagles, and other wildlife. The popularity of the Blackfoot River has led to the development of the special recreation area known as the Blackfoot River Recreation Corridor, with its own unique access opportunities and regulations.

Camping at a designated float-in campsite requires a reservation and permit to be made year round. Camping is not permitted outside of designated float-in campsites within the Blackfoot River Recreation Corridor (Russell Gates to Johnsrud).

There are 8 Float-In overnight sites located along the river that require floating a watercraft into. Each site is completely dispersed camping with no facilities and a maximum group size of 10 people. Fire pans and portable toilet systems are required to be carried and used at these sites:
River Junction
Bear Creek Flats
Clearwater
Ninemile Prairie
Corrick’s River Bend
Ponderosa Flats
