The geology of the area is of interest. See Volcanic rock formations north of Kiama and Volcanic eruption in Australia ’3000 years overdue’! The area in the photos above is known as Black Beach.
It derives its name from the large proportion of black basalt sand and cobbles that compose the curving 130 m long beach, which is located at the base of Kiama Harbour and faces east out the harbour entrance. The beach is backed by continuous seawall and walkway, then tall Norfolk Island pines and Black Reserve and picnic area, with all the amenities of Kiama behind, while Blow Hole Point with its famous blowhole extends out past the harbour.
