Sun Canyon Campground is a primitive, pack-it-in/pack-it-out Forest Service site in the Helena-Lewis and Clark National Forest near Gibson Reservoir and the Sun River, offering access to fishing and backcountry exploration with no water or restroom facilities.

Located approximately 25 miles west of Augusta, Montana, the campground provides a gateway to hiking and biking trails, including the Sun Canyon Trail leading toward the Bob Marshall Wilderness, though visitors should be bear-aware as the area has healthy populations of both black and grizzly bears.

The campground typically operates seasonally from late spring through fall and is best suited for experienced campers seeking solitude and self-sufficient backcountry camping.
