As entertaining as the wildlife sanctuary was, we weren't done exploring. It was nearing lunch time, so we drove a little further down the road to the Marakoopa Cave visitor centre to book our tickets for an afternoon tour. With that taken care of, we had some lunch (with about 100 march flies) and did the short rainforest walk that tracks along Marakoopa Creek.
Marakoopa Cave is nowhere near as spectacular as some of the caves we have been to closer to home in the south west of Western Australia, but that didn't mean we didn't enjoy the cave tour because, like most limestone caves, it had it's own unique character.
