 Mount Osmond is composed of the Mount itself and a ridge ( Long Ridge ) stretching out to the south @-@ east between the valley of the South Eastern Freeway and that of Waterfall Gully . Much of the suburb is more than 300 metres above sea level , with the Mount Osmond peak itself ( located in the Golf Course grounds near the club house ) at 384 metres . Between the north @-@ east and north @-@ west are slopes leading down to the suburbs of Beaumont , Glen Osmond and Waterfall Gully , most of which is owned as public land by various government departments – either as parks , tracks or vacant land for possible future use . A somewhat " ring " of reserves exist on the slopes anti @-@ clockwise from the Old Bullock Track to Mount Osmond Road near the freeway interchange . The South Australian Department of Environment , Water and Natural Resources is responsible for maintaining the Mount Osmond Reserve , which is accessible via Dashwood Gully Reserve and Waterfall Gully Road .
