The Four Brothers Rocks are in the Bunyip State Park, 65 km east of Melbourne.
The Rocks and viewpoint are deep in the Park, and are at the highest point in the Black Snake Range, about 420 metres above sea level.
Vehicular access (4WD or AWD recommended) is via steep, winding, scenic and rough roads through the forest, then a 2 km return walk.
I visited the Rocks on Thursday afternoon March 18, 2010 - my last visit was in September 2005.
My route was from the south, along Monash Freeway, Tynong North Rd, Gembrook-Tonimbuk Rd, Link Rd, Burgess Rd, to the signed parking area where there is a gate. From this point, it is a 1 km walk along Burgess Rd to the Rocks.
An alternative route is from the north, from Black Snake Creek Rd and then on to Link Rd.
The views from the Rocks are spectacular, looking north across the Park to the Blue Range.
Much of the forest adjacent to the Rocks was burnt out in the 2009 fires, but there has been significant regrowth.
Adventurous souls might wish to walk to the Rocks all the way from the Mortimer Picnic Ground, up Triangle Track, which leads in to Link Rd. Since the fires, gates have been installed across Triangle Track, to prevent private vehicular access into Link Rd.
