Flanked by Bundeen Reserve and Bundeena Wharf in the east and Cabbage Tree Point Reserve in the northwest, Horderns Beach is a narrow, 700m-long, sandy beach in Bundeena Bay on the eastern edge of Royal National Park.
Bundeena is not part of Royal National Park and if you were driving and merely passing through to Bundeena without stopping within the national park, you would not need to pay an entry fee at the gate to the national park. Just say you're going to Bundeena.
Another way of reaching Bundeena is by ferry from Cronulla across Port Hacking. The ferry wharf at Cronulla lies just west of Cronulla train station.
Horderns Beach backs into Bundeena township, and across the wharf to the east lies two other Bundeena beaches &mash; Gunyah and Jibbon.
Bundeena is said to take its name from an Aboriginal word meaning "noise like thunder" and traces of the original inhabitants, the Dharawal people, are to be seen in rock carvings and middens (seafood shell piles).
