The Tertiary basalt that forms the headlands between Lennox Head and Ballina has been eroded to form two boulder beaches. The first, Boulder Beach (NSW 22), is located on the southern side of Lennox Head with the Coast Road sweeping round its rear with an access road and car parking at the southern end. It consists of a 600 m long high tide boulder beach backed by a freshwater swamp, and a low tide sand beach and surf zone. The sandy inner bar is usually attached with often strong rips located against either headland, and at times one crossing the bar in a northerly direction. The rhythmic outer bar has a similar number of rips owing to the headland controls. On the south side of the road access and a boundary point called Iron Peg, is a second 100 m long steep boulder beach (NSW 23), with little and often no sand (Fig. 4.19). Under calm conditions at low tide it exposes some calm tidal pools in amongst the rocks, however it is dangerous when wave are breaking. read more
