Caves Beach is the name of both a suburb and beach on the Swansea peninsula, roughly 30 kilometres south of Newcastle and just to the east of Lake Macquarie. The beach is named for the network of sculptural sea caves spread along its southern end, which are wondrous to explore, especially for kids. But a caveat: they can only be accessed at low tide. The beach is patrolled, and is ideal for both swimmers and surfers.
