What to Expect from the Double Dive Experience

We love how this tour is tailored for certified divers who are looking for something beyond the typical beach holiday. The Azores are famous for their volcanic origins, and the underwater scenery here reflects that with lava formations and volcanic rock walls that are unlike anything you’ll see elsewhere.

This is essential, especially for those unfamiliar with the specific conditions of the Azorean waters. The guides are described as knowledgeable and friendly, making even nervous divers feel more at ease.
The real highlight begins once you’re in the water. You’ll do two dives, each around an hour long, exploring different sites depending on weather conditions and your experience level.
