Blackfellows Cave

Blackfellows Cave, located in Blackfellows Caves, South Australia, is a notable sea cave eroded into the low limestone bluffs along the coastline. The area features two beaches on either side of the outcrop, with the eastern beach extending 1.4 km and offering protection from offshore reefs, making it suitable for boat anchorage. The reefs shield the entire beach, with wave heights increasing from less than 0.5 m to up to 1 m at the eastern end, where the beach narrows and is backed by a high tide cobble beach. A continuous bar parallels the beach, with permanent reef-induced rip circulation dominating the eastern end.
