Clontarf Beach (SH 15) is a large sandy foreland that has been formed by ocean waves pushing sand deep into this part of Middle Harbour, 5 km from the Heads. The waves have built out the beach up to 300 m, providing the low sandy foreland now occupied by Clontarf Park and beachfront homes along Monash Crescent. The park has long been a popular area, with daytrippers arriving by ferry in the 19th century and now by car and boat. The park has amenities, a kiosk and is fronted by a netted tidal pool (Fig. 4.227). The beach is moderately steep, with a narrow strip of intertidal sand, then the deeper water of the harbour. It trends 440 m along the southwest-facing side of the foreland, which is backed by beachfront houses, then the park. It then continues for another 200 m along the northern northwest-facing side, which includes the tidal pool and which terminates at the mouth of a small creek. Beach SH 16 continues north of the creek for 130 m to a seawall and rocky point. It is a low energy, west-facing strip of sand and fronted by 50 m wide sand flats, with the Clontarf Marina and jetty crossing the northern end of the beach. Numerous boats are moored off the northern side of Clontarf and adjacent Sandy Bay, with the Clontarf Marine located on the boundary between the two, providing access and service for the boats. read more
