A couple of you have asked how we got on so here are some photos.
We found the cave wasn't really a cave as such. More a small tunnel.
The entrance was very small though and was a bit of a belly slide.

this is looking up

and some steps heading towards the back

There were loads of cave spiders though, Meta menardi and I think Meta bourneti. They all had egg sacks too and I think I saw some slings.
All the white blobs are egg sacks. I suspect there were 50 to 100 in total.

Here is a mum protecting the egg sack

No scorpions or centipedes though but it was small, I couldn't stand up and had to slide about in places, just big enough to turn arround in.
this is looking out form halfway.

My wife crawled to the end too and I took my son a little way in. He wanted to go further but I wouldn't let him. I did hear some bats and saw one flying so decided to leave.
I might have to go back though
