Do be careful driving along the road through the Gorge as many people, such as ourselves, stop to take pictures from their cars of the cute animals grazing on the cliffside. The road is very winding and you might come around a bend and smash into the back end of another car if you aren't paying attention.
Because the area is of karst limestone, the rock is liable to crack and fall. There are warning notices reminding people that rock fall is liable at any time, so be careful. This applies to where you park your car too.
Inside the caves the passages can be slippery and wet, so take care walking or hold onto hand rails, and be careful of low passages.
