Advanced freshwater sinkhole dive with torch-needed caverns.
Advanced freshwater sinkhole dive with torch-needed caverns.
A collapsed dolomite cavern turned freshwater sinkhole, Wondergat is a demanding inland dive with steep walls, dark water, and a memorable bell chamber and memorial stones. Advanced divers come for the shore entry, on-site fills, basic camping, and a classic technical profile that changes with the seasons. Torch use is part of the routine here, and the site rewards divers comfortable in an overhead environment.
