These natural rock formations are just 10 km west of Omarama.
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, or you can pay the $5 vehicle admission fee at the Omarama i-SITE.
To get to the Clay Cliffs, turn onto Quailburn Rd off SH8 and then onto unsealed Henburn Rd.
The Omarama hot tubs, back on the main highway, make for a great stop afterwards.
