The one trail that everyone does on Mt Coot-tha is the Summit Track. Now, thanks to the opening of the new Mahogany Trail, you can walk a 4.5 km circuit from Mt Coot-tha Summit to the JC Slaughter Falls Picnic Area. This is a great walk with many scenic and interesting spots to stop at on the way.
The Summit Track is a pleasant walk that heads down from the Lookout to the JC Slaughter Falls picnic area. The first part has stairs. People looking to run the circuit usually go in the opposite direction, so that they are coming up the stairs and going down the Mahogany Trail, as this is much easier on your knees.
