Inland South Africa offers a distinct freshwater diving experience built around spring-fed lakes, flooded dolomite quarries, and submerged sinkholes. Sub-areas range from Bass Lake, with its artificial reefs and wrecks, to the demanding cave systems at Wondergat and Komati Springs. Most sites suit beginners through shore entry and shallow training areas, while Wondergat's deep shaft caters to technical and cave divers. Tilapia is the most frequently observed species, with Large Mouth Bass and Blue Tilapia also sighted. The variety of site types across five distinct sub-areas gives inland diving here a character unlike any coastal diving.

Fin maps 11 sites in Inland (11 scuba diving sites), organised into 5 areas.
A high-altitude freshwater sinkhole and one of the world's deepest submerged caves, reserved for technical divers.
The most commonly observed species is Tilapia, present across the vast majority of sites. Blue Tilapia and Large Mouth Bass are occasionally sighted, while Crab, Freshwater Shrimp, and Snail have also been observed. The species list reflects the freshwater nature of these spring and quarry environments.
Most sites are rated for beginner divers and offer shore entry with shallow areas well suited to training. Miracle Waters and Marico Oog both feature ample shallow zones, and Bass Lake has a gentle walk-in slope. Wondergat is the exception, requiring advanced or technical certification due to its deep sinkhole shaft and overhead environment.
Bass Lake stands out for its artificial reefs and wrecks, providing varied topography for beginners. Komati Springs combines an open water area with an extensive cave system, while Wondergat is a demanding submerged sinkhole for technical divers. Miracle Waters is a former dolomite quarry with a wide depth range that works well for training, and Marico Oog is a spring with a shallower profile.
The majority of sites are shore-access only, with divers entering directly from the bank or edge of the spring or quarry. Bass Lake is the exception, offering both shore and boat entry. No tidal or surge considerations apply, as all sites are freshwater and landlocked.
