the hut you can see in the pic is the free bbq. it has lighting so can be used at night and also a 240v power outlet. just out of shot to the left is another hut the same with table and chairs and a large double sink. its only cold water and it is drinkable but they recommend using your own water for drinking if you have it.
we did use the bbq once when our burner died temporarily, but otherwise we only used the toilets and were self contained for the rest. it was nice knowing you had the back up if needed though.
now the search begins for next time
this was a nice spot, but once you have done the caves and all the walk tracks, there really isn't that much to do. the caves are quite pricey as well, so if we returned they would probably be off the table, so it really is a sort of once only type spot, and sort of explains why it was pretty low key and most campers only stayed for one or 2 nights.
