Explore Santa Maria Island in the Azores with a 3-hour double scuba experience, encountering vibrant marine life including mobulas and pelagic species.
If you’re a certified diver heading to Portugal’s Azores, the Double Dive in Santa Maria Island offers a fantastic opportunity to explore some of the world’s most captivating underwater scenery. Priced at $188 per person and lasting roughly 3 hours, this tour promises two guided dives with a focus on marine life, volcanic formations, and the chance to spot migratory species like whale sharks. Portugal Dive, rated 4.3, organizes this experience, which seems to strike a good balance between adventure and accessibility.
One of the standout features we love is the small group setup, limited to just 8 participants. This means you’re likely to get personalized attention from guides like André or Joana, who are known for their professionalism and friendly approach. The clarity of the waters and the chance to see pelagic species such as mobulas make this tour especially appealing for those wanting a true underwater spectacle.
A possible consideration is that this experience is strictly for certified divers, so if you’re not yet certified or haven’t dived in over a year, you’ll need to update your skills or reactivate your certification. Also, the tour’s duration is relatively short, so if you’re looking for a full-day excursion, this might feel limited in comparison.
This tour is ideal for diving enthusiasts who already possess certification and want to experience the Azores’ underwater riches. It’s best suited for travelers who enjoy small, guided groups and value knowledgeable guides who focus on responsible interaction with marine environments. Now, let’s explore what makes this experience truly special.


The Double Dive in Santa Maria offers a well-organized, authentic experience for certified divers eager to see the Azores’ underwater treasures. The tour combines safety, education, and adventure, providing two guided dives from a comfortable speedboat. The experience begins at Estrada da Marina, where the crew handles the initial safety briefing and equipment setup. This briefing is concise yet thorough, covering dive plans and emphasizing respectful interaction with marine life.
The boat ride itself, lasting about 15 minutes, takes you to the dive site—location details are shared upon booking, often close to your accommodation for convenience. Once on site, you’ll gear up and start your dives, each lasting around an hour. The waters here are renowned for their crystal-clear visibility and volcanic landscapes, offering a surreal underwater backdrop.
The marine life you encounter is diverse and abundant. Many reviewers mention seeing mobulas, pelagic fish, and a generally vibrant ecosystem. As Santa Maria is on a migratory route for whale sharks, some lucky divers have the chance to catch a glimpse of these gentle giants, adding an exciting aspect to the experience.

This transfer provides a chance to enjoy views of Santa Maria’s coastline and volcanic landscapes from the water, building anticipation for the underwater adventure ahead.

Expect to see an array of marine life, from small colorful fish to larger pelagic species.

The chances to see mobulas are high, with some guides mentioning that these graceful rays are a common sight here. The waters also host other pelagic species, adding to the diversity. If you’re lucky, you may see whale sharks passing through—Santa Maria’s position on their migratory route makes this a potential, though not guaranteed, highlight.
