Hiking and Cliff Jumping: Cairns is super close to some really cool rainforest area. I think the rainforest is beautiful and it’s home to unique animals that you literally cannot find anywhere else. I didn’t get to do as much hiking as I would have liked, but I did get up to see this beautiful waterfall at Crystal Cascades. It was the perfect opportunity for a swim to cool off from the intense heat. You can also jump off the top of the waterfall if the water level is high enough. Be careful though, since if you don’t land in the right area, it’s not deep enough to jump and there are sharp rocks. There are other areas to jump as well, with deeper pools that might me more suitable.
