The dive

A hydrothermal cave in the same system as the Cueva del Agua: the air is 28–30 °C at 99% humidity, the water 29–31 °C. Underwater it is heavily sedimented and turbid; the explorers stopped surveying because of the poor visibility.

Extreme physical load: 220 m of shafts with gear at ~30 °C and 99% humidity – risk of overheating and dehydration before you even dive.

This is how the planner decides who in your team may dive this cave. Rules your own trip adds (organizer, a mail, the AI) show with your trip.

How to get there

Caving expedition only: small entrance on the Cabezo de Hornos, then narrow fissures and shafts down to the water at ~-220 m; all dive gear has to go down with you. Contact the Murcia caving groups exploring it.

Certification requirements, configurations and trimix depths are estimates for planning. Always check them locally and dive within your training. Compiled from web research (Alicante province cave catalogue, CENM catastro and Grupo Cueva del Agua in Murcia, Benitatxell town hall, Región de Murcia tourism, MAPA/BOE, caving clubs, dive centres and news; Sept 2026), and for the Cueva del Elefante the site of the Celacanto dive centre in Altea (Oct 2026). Pins from caving catalogues (converted from ED50) and OpenStreetMap; ~ = estimate. Rules change – check locally.
