A challenging bushwalk to the Grose River in the Devils Wilderness. The route follows Browns Ridge along the Browns Ridge Trail, before a steep descent into the Grose Gorge via Browns Creek.
A challenging bushwalk offering spectacular views in the Wolgan Valley. The off-track route ascends to Constance Point via a narrow pass in the cliffs before continuing along Constance Ridge to Tiger Snake Point. Return via Constance Gorge and Zobels Gully.
