This was a tiring day climbing up and down the path around the Gower. The geology here means there are many steep valleys that you climb down into down steep paths and then back out by what generally seem to be steeper paths.
Geologically interesting = steep paths
Geologically wonderful = very steep paths
Geologically stupendous = you need rope and pitons.
I finally settled into a wild camp conveniently next to National Trust cafe with toilet and water.
