Time Out says
There’s a reason the Grampians bring bushwalkers back time and time again. Rough and rocky on first glance, it surprises visitors with hidden waterfalls, hollow mountains and incredible natural amphitheatres. The walk towards the Pinnacle starts at the Sundial car park where hikers can climb through fun geological terrain towards a big lump of rock overlooking Fyans Valley. If you’d like to test your fitness, there’s also a harder climb to the same destination that starts at the Wonderland carpark.
