epic one way 13 day/164km through hike that spans the entire length of Gariwerd Grampians, from Mt Zero in the north to Dunkeld in the south (need a car shuttle or book transfers with https://grampianspeaks.com.au/) but can be done in shorter sections
mostly Grade 4-5 hiking with lots of rock scrambling and average speeds of 1.5-2kph - so those 8-16km day sections may take a whole day!
great camp sites (fees of ~$47/night) with water tanks, drop toilets and solar powered USB charging points and can accommodate 20-24 hikers
Tent pads are either timber platforms with heavy retractable chainlink to anchor your tent, or firm packed granite sand.
