Definitely a place to visit - fascinating!
This is a great place to go for a good day out.
The grottos are huge and there are three trips of varying lengths.
We took the 1 and a half hour tour and it was amazing.
They also do some other specialised tours off the main tracks (for the more adventurous, you need to be properly kitted out and booking in advance needed).
Open all year.
From 1 March to 31 October
9:00 – 19:00
