Take a walk from one of the main visitor areas up onto the main ridge. The walking tracks to this area are sealed, but can be steep. No need for more than 30-40m of off track walking. Muggles at a minimum most of the time.
You need to pay for parking at the Carnley and Richley carparks. Park at Queens Rd carpark for free and a long, pleasant walk….
