Palouse Divide West - FS 377

Trail Overview

Palouse Divide West (FS 377) is a 15.3 point-to-point trail that, when starting from the west side, begins at the end of Big Creek Road. It winds down into the backside of Prospect Peak into a valley and continues along Meadow Creek for several miles before making a sharp left shown in the second picture. After turning left, Palouse Divide climbs out of the valley and up towards West Dennis. Note that from 9 to 9.3 miles, Palouse Divide passes through private property. The boundaries are well-marked and can also be viewed using the private property layer on OnX. Starting at this section of private property and for several miles after, the road is heavily rutted and damaged by heavy logging equipment. As of October 2025, there is active logging along the trail. After passing out of the active logging area, the road surface becomes gravel, wide, and well-maintained until it ends at an intersection with Idaho Highway 6. Palouse Divide West is open from April 1st to December 1st.
