These natural rock formations are just 10 km west of Ōmarama.
The Clay Cliffs are a stark sight - tall pinnacles separated by narrow ravines.
These otherworldly formations are made up of layers of gravel and silt, originally formed by the flow from ancient glaciers over a million years ago.
The cliffs are on private land. There's a donation box at the gate where you can pay the $5 vehicle admission fee.
To get to the Clay Cliffs, turn onto Quailburn Rd off SH8 and then onto unsealed Henburn Rd.
The Ōmarama hot tubs, back on the main highway, make for a great stop afterwards.
