With the caves only a short distance from the main road this is a great place to pit stop and explore or as day trip if you do both the caves and the waterfall 20minutes south of the caves. I was at the caves on Dec 29 2017, on this date when we entered the main cave you could follow straight and continue by walking through knee deep water and bending down under long, low rocks, this is the way to go to see the best glow worms, it is eventually a dead end and so is hard to get lost in. If you turn right after just entering the cave there is a very large, shoulder-deep stream you can swim through that will take you on a loop back out to the main grassy area. There is a Doc campsite here. If you follow a small track going left instead of entering the caves, you can follow it up the bank and explore massive rocks in an odd formation. Most people will say to wear gumboots or shoes to help with the slippery floors but I found it best to wear bare feet so I didn’t ruin any shoes and got more feel out of the experience.
