Middle Fork Flathead River

Middle Fork Flathead River Professional Review and Guide

"A picturesque wilderness whitewater river, the Middle Fork is both extremely challenging and remote. The Middle Fork roars through the Bob Marshall Wilderness and forms the southern border of Glacier National Park.

Extremely difficult whitewater in the wilderness section, with Class IV rapids or better at peak flows. Experts only. Class II, III, and IV rapids outside the wilderness.

The Middle Fork is one of Montana’s best-protected rivers. It flows through the wilderness for half its length, and it forms the southern border of Glacier National Park for the other half. The biggest problem this river faces is potential overuse, but the Forest Service so far has done an excellent job of managing people problems."
