About the Walking Trail
A challenging circuit hike to the summit of the Flinders Ranges highest mountain – St Mary Peak/Ngarri Mudlanha at 1,171m. Rewarding panoramic views of the Flinders Ranges, Aroona Valley, and the salt plains to the west.
Hike times:
- The direct route (up the on the escarpment edge) is 6 hours and 14.6km return.
- The loop route is 9 hours and 21.5km.
- Rangers recommend you leave on this hike no later than 9am (10am during daylight saving).
A good option is to make it into a two day hike by camping at Cooinda Camp inside Wilpena Pound, but note there are no water or toilet facilities at this campsite. 1 April 2020: the campsite at Cooinda has been closed. The site was a largely a historic, informal camping area. The conditions had become unhygienic and it was in close proximity to a cultural site. (An alternative campsite for hikers has been established further along the Heysen Trail at the Wilcolo Track – but note this is not relevant for the St Mary Peak hike.)
