Never encouraged
No swimming to the cave, flotation-aid access, unguided rental approach, landing on cave sand or entry from the roof opening.
Method
Authority first. No unsafe inference.
The maritime authority sets access rules and restrictions. We explain what those notices mean for trip choices, while every current decision remains with the authority and compliant operator.
Rules checked
Edital 019/2024, amendment 009/2025 and the separate landing-licence Edital 001/2026 were reviewed 5 August 2026. The 2026 notice does not replace the cave-navigation rules; the live Portimão notice page remains the final check.
Live facts stay live
Closures, sea state, operator status, bus times and trail restrictions are never presented as future guarantees.
