Locks Well Beach on the Yorke Peninsula is a challenging shore entry site suited only for expert divers and snorkellers. The topography consists of a reef system subject to significant surge and strong surf. Entry requires navigating a high-energy surf zone, and the site is frequently affected by dangerous rip currents and moderate to strong currents. Visibility is variable, often ranging from 2 metres upwards. The site is primarily known for its dynamic conditions rather than calm water. While the habitat supports a variety of temperate marine life, the site is considered hazardous for swimming and is not recommended for casual snorkelling.

Investigator Marine Park, located off the Yorke Peninsula, features a diverse range of underwater topography including reefs, walls, kelp forests, and caves. Depths range from the shallows down to 50 metres, requiring careful gas and bottom time planning.
