The land is home to mobs of kangaroos, and a special viewing area has been constructed.
The entrance to Highfield (well signposted) is reached from the Boneo Rd, between Flinders and Cape Schanck Rd - there is a small car park next to the Parks Vic gate.
The main walking track heads north, passing the Highfield Bunkhouse (basic paid accomodation for backpackers) and the Parks Vic depot (an old farm shed!) It continues to a junction with other signed tracks.
My visit was on May 8 2012, a 3 km hike.
