Hell’s Hole

A view like no other …

Hell’s Hole is one of the most impressive karst features in the Limestone Coast.

It is a cenote – a sinkhole that extends into open water – and is approximately 45m in diameter, 25m deep and 38m below the viewing platform.

A walking trail has been established at the site, which meanders uphill to the sinkhole with an easy walk to the carpark.

Take a deep breath before you step onto the viewing platform – the view in to Hell’s Hole is like nothing you have experienced before!

While anyone can visit and take in the view from the platform, Hell’s Hole is also popular among divers. To dive at Hell’s hole, divers must obtain a ForestrySA permit and be a member of either the Cave Diving Association of Australia (CDAA) or Australian Cave Explorers (ACE).
