Great Salt Plains State Park is one of Oklahoma's most unique state parks.  The barren landscape of the Great Salt Plains is comprised of salt left over 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, such as swimming in Great Salt Plains Lake or trekking along bike trails. Equestrians can bring their horses to Great Salt Plains State Park to ride designated trails, and there are nature trails to enjoy while taking in the scenery.  Fishing at Great Salt Plains Lake is fun for the entire family, whether in a boat or on shore.  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.
