Four Brothers Rocks is a 13.9km, grade 3 Circuit hike located in Bunyip State Park Victoria. The hike should take approximately 5hrs to complete.


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.

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.

  1. 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.

  2. 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.

    1. 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.

  3. 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.
