Scaling Mt Ohlssen-Bagge is a just-as-scenic, fun alternative to climbing St Mary Peak, leading lady in the Adnyamathanha creation legend about (and high point of) Wilpena Pound. About 7km return, the walk-clamber takes you to the top of the rocky pile that guards the gap through which Wilpena Creek leaves (and hikers enter) the Flinders Ranges landmark and bushwalking South Australia hot spot.
From the visitor information centre, the hike follows the creek west, through river gums frequented by green-and-yellow Mallee ring-neck parrots. It then veers left, across the creek, and almost immediately starts climbing, up lumps of red rock that in places appear to have been stacked like a giant staircase. The walk rounds the pound’s outer wall and then climbs a natural ladder to a saddle offering your first view into the Pound. A few hundred metres more and you’re on top of the steep, sloping rim.
From here you’ve got a breathtaking 360-degree view of the extraordinary natural bowl, St Mary Peak and the elongated, almost finger-like ABC and Red ranges.
