Grampians National Park, VIC
Steep gully scramble to wind-scoured caverns above the Wimmera Plains
Overview
Good for fit, confident walkers who enjoy using their hands and don't mind steep, uneven rock. The summit views are the clear payoff. Steep, uneven rock and hands-on scrambling are required in both directions, so take this on only if you are fit, sure-footed and comfortable climbing and descending rock; if not, pick a different walk.

Trail guide
An out-and-back climb of 2.2 km return, retracing the same route down, with about 2 hours the typical time on foot. The distance is small, the effort is not: this is rated Grade 4 / Medium-Hard, and it sits around 7/10 for practical difficulty.
Expect rock hopping and genuine rock scrambling, not just walking. Independent measurement of the route puts the high point near 372 m and the low point near 230 m, so roughly 180 m of climbing packed into just over a kilometre each way. Track surfaces can be slippery, and the upper ledges and slabs involve rocky, exposed ground where a slip matters more than a stumble on dirt. Trail markings are yellow symbols and visibility along the route is generally good, but route-finding attention is still needed once you are on rock.
