West Fork Lost Fork is a hard, out-and-back hike of about 10 miles in the Judith-Musselshell Ranger District of Montana's Helena-Lewis and Clark National Forest. It starts at roughly 6,068 feet and climbs to about 8,049 feet, a gain of nearly 2,000 feet one way, making it a serious outing on natural trail surfaces. The trail is open year round, and it is used for both horseback riding and mountain biking, so plan for a ride on either. It is not an accessible trail, so be prepared for a rugged route that won't accommodate mobility aids. The nearest neighbors are the Burris-Ettien hike, about 2 miles away, and Halzel Coulee, about 3 miles off. For overnight stays, Hunters Spring Cabin lies about 6 miles away, and paddlers can head to the Middle Fork Judith River, roughly 7 miles away.
