Dive Spot Guide•
Rhisnes
Rhisnes is a quarry dive with open water and an overhead mine section.
Book ahead, expect silt and low visibility in the quarry basin, and treat the mine section as a qualified overhead route.
About Rhisnes
Rhisnes is a quarry dive with an open-water basin and a separate overhead mine section for qualified cave divers. The site combines simple quarry terrain, old working spaces, and a tighter route that becomes more technical once you leave the basin. Plan ahead for paid access, careful buoyancy, and fine silt that can cut visibility quickly. It suits divers who want a Belgian quarry day with a more demanding overhead option.

Safety Notes
Use strict buoyancy control because silt lifts easily. The mine and gallery sections are overhead spaces and should only be entered with cave or cavern training, redundant lights, and a clear turn plan.

Advance registration and paid access are required. Solo diving is not allowed, and the overhead section is restricted to properly trained divers.
Legal Notes
Use the site under its posted booking and group rules; the overhead section is for properly qualified divers.
Local Intel For Rhisnes
Community notes to help plan your visit.
Scuba Diving
The open quarry works as a straightforward quarry dive, while the mine/gallery line turns more technical once you leave the basin. Keep buoyancy tight and plan a conservative exit before entering the overhead section.
Freediving
Not a practical freedive target. The interesting sections sit deeper and the overhead routes are meant for qualified scuba divers.
Snorkeling
Casual snorkeling has limited value here; the site is about quarry structure and deeper mine routes rather than a shallow snorkel loop.
