Named after the roadway that encircles the north-west promontory of the Castle Cove headland. The reserve was acquired in 1961 and 1968 from Headland Developments Pty Ltd. when the land was subdivided into large housing blocks. The high cliff-top site has commanding views up the Roseville Reach of Middle Harbour towards the Roseville Bridge and Killarney Heights.
Two park benches are located in the bushland setting to take advantage of the views. There are steps down from the road, a brick path to one bench and a short bush track to the other.
