Arkaroola permits people to walk throughout the Sanctuary but they suggest itineraries for 4 or 5 half-day walks and one full day. Which one to choose? If you intend going on the 4WD Ridgetop tour it might be better to undertake some of the walks which traverse creeks and gorges rather than the high country as you certainly see plenty of ridgetops on the ridgetop tour! One of the half day walks; Barraranna Circuit walk takes you through Arkaroola creek which has a great picnic area where Bararranna gorge meets Arkaroola creek and you may well have yellow footed wallabies chaperoning you. A detour from the circuit takes you to Bararranna waterhole. Some scrambling and rock hopping is needed to get to the waterhole but the effort is well rewarded, the waterhole has an eerie waterhole at the end of the world feel.
