There's only one way in and one way out. The way in is either a 20m cliff jump or a smaller 10m cliff jump. You than have to climb up a rope to get back up. If you want to get to Mermaid Pools, drive to the car park off Charles Point Road, Tahmoor, and then take a 45-minute walk. Head deeper into the bush to visit Sugar Loaf Pass, Tahmoor Gorge and Pencil Falls, but do be careful, as signposting is limited and the trail gets steep, and a woman tragically died here in 2014.
