Diving in Caves

The geographical make-up of the volcanic Azores creates a fascinating underwater playground. As well as unique physiography, it also provides dive sites with an added geological interest, especially for those who love diving in caves.

Tunnels, sometimes several metres long, connect to large caves, often interconnected with other chambers and impressive caverns. Their origin dates back to the formation of the islands themselves, when lava reached the sea and solidified too quickly on the outside but continued to flow on the inside. The result is a maze-like structure that is perfect for exploratory dives.
