The rugged terrain and breathtaking views in Mary McCroskey State Park are best suited for those with a sturdy vehicle and an adventurous spirit.
The eighteen-mile unimproved Skyline Drive winds through the park, rising through dense cedar and ponderosa pine forests to spectacular vistas of the rolling Palouse prairie. The road grants access to 32 miles of multi-purpose trails for hikers, horseback riders, mountain bikers and all-terrain vehicles.
