New Zealand South Island Road Trip 2025 – Clay Cliffs

From Wanaka at the end of the Haast Pass we head up to Omarama for another geological wonder, the Clay Cliffs.

We miss timed it a bit and got there pretty much at noon which meant the contrasting light made photography difficult but hopefully the epicness of the landscape still came through.

The Omarama Clay Cliffs are on private land and there’s a honesty system donation to enter.

Formed from millions of years of sediment deposit at the bottom of a lake then uplifted and tilted, the Clay Cliffs are a classic example of what is termed “Badlands erosion”

They really are spectacular.

Kylie has a much better and more scientific explanation of these formations.

Here’s what she said

“I still remember the first time our lecturer brought us here and told us to “run wild and free” as he explained to us this magnificent example of tectonics in action. The Clay Cliffs are sedimentary deposits that were once the base of river bed. Due to the position of the Ostler Fault line under the South Island of New Zealand the river bed has been uplifted overtime and then eroded to form these strikingly alien planet like features.

New Zealand is an amazing country to see Earth in motion, similar to Iceland where tectonic forces are still very much at play building the landscape as we speak. Unlike Australia that is so ancient it only erodes now.

Anyway the Clay Cliffs are totally cool, I’m still finding new parts of it to explore every time I come back.”

After spending most of the afternoon here we jump in the van and make tracks up to Aoraki aka Mount Cook.

Clarence Dams 11-01-17

With all the people who visit the Railway dams on Dargan crk at Clarence now days I wonder how many have ventured up into the backwater. It had been ages since I’ve done it.

As well as leaps of faith the main wall is also great for deep water soloing

There are lots of climbable lines on the wall, however most involve a blank section 3/4 the way up that require a long stretch or balancey moves on tiny climps while trying to smear with bare feet.

If you have a bit of reach the green route is by far the easiest. For someone around the 180cm mark it’s only about a grade 16. Where the higher climber’s elbow is in the pic is a sneaky under cling. By stepping down and to the left  you can then come back up right, use your right hand to pull you into the wall with the under cling, this allows you to push up off your right foot while stretching your left hand straight up. A seemingly small hold just within reach is in fact a very nice jug. The black line is the hardest I have managed to do, way back when I was climbing lots. It involves a cool move to get over the shelf and a big dyno further up where the wall gets blank. I only managed it once. the Blue and purple traverse lines would be around 17. The red and Yellow lines were always a bit beyond me.
