This trail begins at the entrance to Lake Fork Ranch where the Lake Fork Trailhead is located. It is a gentle hike along the Lake Fork Creek to Big Lake. The trail then climbs steeply to a saddle between Forest King Mountain and Mammoth Mountain and drops steeply into the community of Platoro.
Dividing the Lake Fork Trail makes a pleasant day hike from either Lake Fork Campground to Big Lake and return, or from Platoro to Big Lake and return.
Fishing Lake Fork Creek from Rock Lake to Big Lake is flies only and catch and release, due to the stocking of cutthroat in this section of the creek and the lake.
Platoro is heavily used during the summer and advance reservations are usually necessary for lodging.
