We followed the creek (above right) to the causeway. The track along the creek was overgrown until after Blue Pool, and although its picturesque, you don't have to reach the causeway by this route. (see the links at the bottom of the page).

From the causeway we walked the Campfire Creek track to Redhands Cave, before returning to the station along Bruce Road via the park entrance.
