How to visitFree; on private land with public access (dirt roads, stay on the path)
A cluster of 70-foot chalk spires and arches rising straight out of the western Kansas wheat — the eroded floor of an ancient inland sea, full of fossils. The very first landmark named a National Natural Landmark, and almost no one’s there.

Plan around it
Access, fees, permits, and tour availability change with the season and the managing agency (tribal park, state park, BLM, or NPS) — confirm current rules and reservations before you go, tread lightly on sacred and fragile sites, and pack out everything you bring.
