Sunday's castle was a cave

The Welsh National Showcaves were about an hour and half's drive from where I'm staying, so I thought it might be a good place to go when the weather was a bit clearer and the views were nice. Which it was, but I was high in the Brecon Beacons for much less time than I expected, so I don't actually have any nice views... So its more caves, I'm afraid!

( I think the lads might have... )
