Wonderland Loop is a 25km, grade 4 Circuit hike located in Grampians National Park Victoria. The hike should take approximately 7hrs to complete.

Summary

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.

Getting there

Grampians National Park is in western Victoria, 260km from Melbourne and 460km from Adelaide. Halls Gaps is 253km west of Melbourne.

About the region

The Grampians National Park (also Gariwerd), commonly referred to as The Grampians, is a national park located in the Grampians region of Victoria, Australia. The 167,219-hectare (413,210-acre) national park is situated between Stawell and Horsham on the Western Highway and Dunkeld on the Glenelg Highway, 260 kilometres (160 mi) west of Melbourne and 460 kilometres (290 mi) east of Adelaide. Proclaimed as a national park on 1 July 1984, the park was listed on the Australian National Heritage List on 15 December 2006 for its outstanding natural beauty and being one of the richest indigenous rock art sites in south-eastern Australia. The Grampians feature a striking series of sandstone mountain ranges.

The general form that the ranges take is; from the west, a series of low-angled sandstone ridges running roughly north-south. The eastern sides of the ridges, where the sedimentary layers have faulted, are steep and spectacular, beyond the vertical in places – notably at Hollow Mountain near Dadswells Bridge at the northern end of the ranges. The most popular walking area for day trippers is the Wonderland area near Halls Gap. In summer the ranges can get very hot and dry. Winter and spring are the best times for walking. The Wonderland area is also host to “The Grand Canyon” on the “Wonderland Loop” on one of the tracks to the “Pinnacle”.

In spring the Grampians wildflowers are a major attraction. The area is a noted rock climbing destination, and it is popular with campers and bushwalkers for its many spectacular views and unspoilt nature.

Mount William is known within the gliding community as the epicentre of the ‘Grampians Wave’, a weather phenomenon enabling glider pilots to reach extreme altitudes above 28,000 ft (8,500 m). This predominantly occurs during the months of May, June, September and October when strong westerly winds flow at right angles to the ridge, and produce a large-scale standing wave (Mountain Lee Wave).
