The Wonderland Loop hike is one that I have pieced together from a series of Grampians trails. It covers most of the Wonderland Loop including the Pinnacle and Sundial Peak before crossing the valley to the opposite ridge.
Note that the section from Lake Bellfield to Boronia Peak is completely off-trail. This section is extensively overgrown and will take a lot of time and effort to navigate.
