Biscoitos Cavern 1, 2, 3
Long volcanic cavern route with multiple exits in Biscoitos.
About Biscoitos Cavern 1, 2, 3
Biscoitos Cavern 1, 2, 3 is a long volcanic route that threads through shallow valleys before reaching a sequence of caverns along the Biscoitos coast. The dive is more about route discipline and overhead awareness than raw depth, with multiple exits and a steady build from open reef sections into the cavern finish. Experienced divers usually treat it as a deliberate equipment-and-gas-planning dive rather than a casual sightseeing loop. The appeal is the combination of lava topography, swim-through structure, and the chance of seeing larger fish moving through the same terrain as the resident reef life.

Key Hazards
Safety Notes

This is typically run with a local operator or divers already familiar with the Biscoitos entries and exits, since route knowledge matters more than finding the waterline.

Scuba
Often dived in sidemount or twin-set configuration and recommended for divers with technical experience.
Freedive

Snorkel
