Sinkhole
Wondergat
A dolomite sinkhole outside Mahikeng used by South African cave and technical divers. Listings describe depths to about 70 m and a Cave 1 prerequisite; owner and access details are not published.
Wondergat is a flooded dolomite sinkhole in North West Province, outside Mahikeng. PADI lists it as one of three dive sites in the province, and a Gauteng club names it as a trip venue.
Published information comes from listings rather than from an owner or authority. They describe a dark cave section with fixed guide ropes, depths of up to about 70 m depending on the season, and an on-site filling station, and they state that a Cave 1 qualification is expected. These points could not be confirmed from a primary source and should be checked before relying on them.
The environment
Fresh water of about 15-20 C with visibility of about 5-10 m, varying with algae. Listings mention a dark cave section where a torch is needed and fixed guide ropes are in place. PADI notes the banded tilapia lives here.
Conditions
Depth and visibility vary with season and algae, according to a listing.
Typical ranges from published sources, not current conditions.
Facilities
An on-site filling station for air or nitrox is mentioned in a listing.
