Mary Minerva McCroskey State Park boasts epic views of the Palouse Divide, lush cedar forests, secluded camping, historic interests, multi-use trails, open Ponderosa stands, and the perfect road for a Sunday afternoon drive.

Skyline Drive, the main access through McCroskey is a gravel road that can be traveled by most vehicles. Skyline Drive is not plowed and becomes snowed in during the winter months. It is essentially one-lane, but wide enough for two vehicles to pass with generous shoulders and numerous pull-outs. Very wide or long recreational vehicles and horse trailers are not recommended without the driver first making their own assessment. Skyline Drive is a little over 17 miles long; mile markers begin at the south entrance of the park, off Highway 95. You may access Skyline Drive from Idaho or Washington.

McCroskey borders federal, private, and tribal lands. As one travels south to north, you will begin your adventure in dense cedar and grand fir forests, on steep north-east facing slopes. Then to southern open skies amongst the ponderosa and Douglas fir stands. On the west side of Skyline Drive and the park, you will get some of the best views of the Palouse imaginable. To the east, one sees the foothills of the Bitterroot Divide on the Idaho Montana border.
