Hike Summary
Bunyip State Park is a 166-square-kilometre state park 65 kilometres east of Melbourne, near the town of Gembrook, in the southern slopes of the Yarra Ranges.
Starting from Mortimer Picnic Ground this Four Brothers Rocks hike follows the old (and non existent) Hacket Track to the junction of Windy Point Road. Turn left onto Burgess Road and follow this to Four Brothers Rocks, a collection of large, granite rocks offering sweeping views across the park.
From Four Brothers Rocks join Nichols Hut Track and follow it down the spur. The last leg of the journey is along Silvertop Ridge Track and Ferres Track, and back to Mortimer Picnic Ground.
About the region
Bunyip State Park is part of an Aboriginal cultural landscape. Parks Victoria respects the deep and continuing connection that Traditional Owners have to these lands and waters, and we recognise their ongoing role in caring for Country. Bunyip State Park is one of the few places in Victoria where our state floral emblem, the Common Heath, and state fauna emblem, the Leadbeater’s Possum, along with our state avian emblem, the Helmeted Honeyeater, can all be found.
Getting there
Drive 38km to Belgrave along the Burwood Highway and continue a further 24km to Gembrook. Drive through town (towards Beenak East) and along the unsealed Gembrook-Tonimbuk Road for 7km to Mortimer Picnic Ground on the left.

I did this walk and it was really great. It is not marked at all and the local instructions are not the best. The view from the brothers rocks is amazing and we saw a lace monitor and a koala come down a tree, walk across the ground and climb another. If you walk it in the direction written above there is a VERY steep downhill section towards the end.
Have to love the steep downhill. Or up hill if you prefer a challenge
I must say allowing 5 hours for this trail is very generous- we did it in 3.5 and that was with a lunch stop. Four brothers rocks was beautiful.
Thanks for the feedback. I’ll change the hours to 3-4. Last time I did this was with a group of kids so we spent a lot of time exploring the rocky outcrops.
We did it couter clockwise and it was nice. The steep part before the Four Brothers was enjoyable. It was great to take our lunch at the Four Brothers as the view really worth it.
Hey folks. Is there a gpx file for this hike? I can’t see it.
Hey Paul. There sure is. There was a stray comma in the coding so I have just removed that and the map now appears. Thanks for the heads up.
Could I reach this trail in a normal car? Or will I need a 4wd?
Hi Shaun, the Gembrook-Tonimbuk Road is unsealed but is suitable for 2WD vehicle.
Ha, the old Hacket Track sure is non existent! Rather than bush bash I continued up Triangle to Windy Point. I’d forgotten I’d been here before a few years ago, then remembered the steep Nichols Hut Track. I was happy to walk down it this time.
Did you use gps to try and find the Hacket track? Considering this soon.
Just a heads up, the trail is currently closed (as of November 2019) because of fires last summer (?)
Presumably due to danger from falling trees and also to allow regeneration.
Thanks for the updated info.
