The McCroskey Skyline Trail is part of a 5300-acre ridgeline park that is dedicated to pioneer women. The St. Joe area hike meanders thru a blend of trees in the Clearwater National Forest, including cedar and colorful decidious. The route follows a ridge line with expansive scenic views of the Palouse hills, Mineral Mountain, and the prairie. There are no entry fees to access the Mary Minerva McCroskey State Park.
