Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Oct 2026): the Tonga Pocket Guide (caves, dive sites and dive operators, updated June–July 2026), the PADI blog (2015), Divernet (2019) on the diver missing in Cathedral Cave, the Freediving Family brochure (2021), Smartraveller and the UK travel advice on Tonga, and Healthpoint on the chamber in Auckland. The dive operators' own websites could not be opened. The pins of Mariner's Cave, Swallows Cave and Shark's Tooth come from the vavau.to diving and snorkelling guide; the other caves have no pin. These are guided boat dives into sea caves and caverns; certification and configurations are estimates.
