From river deposits to dunes
Oklahoma State Parks traces the sand to terrace deposits from a time when the Cimarron River crossed the area. The modern dunes rise about 25 to 75 feet.

Take in the landscape from the viewing area
The Buttercup observation deck provides a way to look out at the sand without entering the vehicle riding area on foot. Keep that distinction in mind when planning a visit with non-riders.

Give the non-riders a plan too
Arrange when the riding group will return, where everyone can meet and how people will spend their time between outings. A good dune weekend works for the whole group.
Read the dunes as a former river landscape
The park connects the sand to old Cimarron River terrace deposits. The modern forms rise around 25 to 75 feet, so this is a substantial dune landscape even though the surrounding trip is through prairie country. Its material and location are different from Utah’s Little Sahara; the shared name does not make the two parks interchangeable.

A weekend that includes Waynoka
Oklahoma Tourism builds its Waynoka itinerary around the dunes and the town together. Leave time for a meal or a town stop outside the riding sessions, especially when the group includes people who are not riding. Keep pedestrian sightseeing at the designated observation area, not among moving machines.
