McCroskey State Park, Wilderness state park in Benewah County, Idaho, US.

McCroskey State Park is a wilderness area of roughly 5,300 acres situated along a mountain ridge and dominated by dense cedar forests mixed with ponderosa pines. The landscape includes views of the Palouse prairie below and transitions between different forest types.

Virgil T. McCroskey (1876–1970) bought up land threatened by logging and gave the 4,400-acre parcel to Idaho in 1955. The legislature accepted only on condition that he maintain the park at his own expense for fifteen years; he did so, dying weeks after fulfilling the obligation in 1970.

The park bears the name of Mary McCroskey, a pioneer woman whose family settled in the region and shaped the land. Visitors can still see how the landscape reflects both early settlement and later conservation efforts.

Skyline Drive is an 18-mile (30 km) narrow, unimproved road along the ridge; the best access is from Highway 95, about ten miles north of Potlatch. The park has 32 miles (51 km) of trails open to hiking, mountain biking, horses and all-terrain vehicles. Primitive campsites, picnic areas and pit toilets are available, with a single drinking-water source near the midpoint of Skyline Drive. The Farmington road entrance on the west side is rougher and marked only by a Skyline Drive sign.

Virgil McCroskey cut viewpoints into the slopes and built picnic areas and a road to draw tourists before handing the land to Idaho. The state doubted the park would pay for itself and accepted only on condition that he maintain it at his own expense for fifteen years. He lived exactly fifteen more years, meeting the obligation weeks before his death in 1970 at 93.
