I went for a wander, and found a lovely cool, deep cave, but couldn't see enough to continue exploring. Anyway, it was a nice relief from the heat. Obviously, you need to take a torch to explore beneath the boulders. Apparently there is a maze of tunnels beneath the boulders, and it is possible to get lost. It also looked like it was possible to falll down a hole which was deeper than you might have expected.
There were some climbers having a go, which was interesting to watch. I'm trying to work out from the climbing guide which climb they were on. Could have been "Stone the Crows". There is a gully directly behind where they were climbing, which I think is the one the climbing guide says is "NOT recommended".
The laid-down columns of dolerite here are really quite spectacular. They are quite chaotic, and when you get beneath them you can see how they are lying higgledy-piggledy across each other, leaving both gaping chasms and deep narrow slots. Some care is required in moving around, but it's not too difficult. There are a couple of quite large drops into black holes, partially obscured by vegetation. If you took children here, they might need to be watched.
