Directions to Trailhead

The South Boundary Trail is a short hike down the Middle Fork Flathead River that boasts views of the surrounding forest. The hike used to carry on longer, but the erosion of the soil and lack of hikers have cut the trail distance down. Most hikers now turn and head back at Lincoln Creek.

Route Description for South Boundary Trail

The South Boundary Trail is known for its winding rivers that switch from large calm pools to rushing rapids along the North Fork Flathead River. This area is not accessed a lot by hikers and can be quite dangerous from spring to August due to high rushing water. The trail begins at the Belton Bridge. Be sure to stick to the right hand side after crossing the river. The first 8.0 km of the hike will take you through a vibrant green forest until you reach Lincoln Creek. At this point, most hikers will enjoy the view and then turn back the way they came.
