It’s a long way up but the views are so worth it!
Mount Rosea is one of the longer walks in the central Grampians, leading your through dense forest at the start following a sandy track up between rock formations and for the last section before you reach the peak, beautiful steep cliffs and a bridge crossing called the Gate of the Eastern Winds. Keep a good eye of the landmarks passing through the latter bit of the walk as you might easily miss a turn on the way back.
