The Lost Park Trail begins on the north side of Rio Blanco County Road 8, just before the Lost Creek Guard Station. Follow Lost Creek Trail #1808 for 4 miles to Lost Park. The Lost Park Trail divides shortly after entering Lost Park, branching up both the east and west forks of Lost Creek. After roughly 2 miles, both forks enter the Routt National Forest, and after another 2 miles, they both join the Salt Park Trail. The South Fork of the Williams Fork River and Salt Park are both accessible from either fork of the trail. Print a trail description and map
