This is without a doubt the coolest thing I have ever done. Our guides Alistair, Hannah, and Christine were fantastic! The caves are spectacular and the guides make it quite comfortable 90m underground. We did the Black Abyss tour but due to low numbers, we also were able to do the Black Labyrinth tour. The caves can we quite tight in some spots but the guides are more than willing to cater for any kind of claustrophobia! The guides had extensive knowledge of the natural features of the caves, their formation and the history of the area. I would very highly recommend this to anyone, buy particularly those who like something a bit physical and a bit challenging!
