Salt Plains State Park is one of Oklahoma's most unique state parks. The barren landscape of the nearby Salt Plains National Wildlife Refuge is comprised of salt leftover from an ocean that covered Oklahoma in prehistoric times, and the saltwater lake in the park, Great Salt Plains Lake, is about half as salty as the ocean.

Visitors can take their pick of activities in the park, bird watching and hiking along the trails. Equestrians can bring their horses to ride designated trails (Equestrian Campgrounds available), and there are nature trails to enjoy while taking in the scenery. Fishing at the lake is fun for the entire family, whether from the shore or the handicap accessible fishing dock. Varieties of fish such as catfish, saugeye, sand bass and hybrid striper can be found in these salty, shallow waters. You can also bring your canoe or kayak and enjoy a trip around the lake viewing the many migratory birds that pass through the area.
