More about Whetstone Gulf State Park...

Whetstone Gulf State Park is built in and around a three-mile-long gorge cut into the eastern edge of the Tug Hill Plateau. The gorge is one of the most spectacular scenic vistas east of the Rocky Mountains. The park has 56 wooded campsites- some of which are electric, a scenic picnic area along Whetstone Creek, a man-made swimming area and trails for hiking and cross-country skiing, one of which circles the gorge. Above the gorge is Whetstone Reservoir, stocked with tiger muskie and large-mouth bass for fishermen, and popular for canoeing.
