The tour begins at Go Shark Azores, located on R. Vasco da Gama, 9900-038 Horta. This central spot is accessible and marked by clear signage for easy arrival. The tour operates daily from 6:00 AM to 8:30 PM from June 2023 through August 2026.
Participants are picked up at this location, and the activity ends back at the same point. The flexible scheduling allows for early morning or late evening departures, matching the best shark activity periods and weather conditions. Being close to public transportation adds convenience, especially for those staying in Horta or nearby.

Upon arrival at Go Shark Azores, guests are welcomed to try on necessary snorkeling equipment and receive a detailed briefing from Silvio. His clear explanations cover shark behavior, safety procedures, and what to expect during the activity.
This initial step helps build confidence, especially for those new to snorkeling or shark encounters. The briefing emphasizes respecting marine life and maintaining safe distances, fostering a responsible approach to close encounters with sharks.
Before encountering sharks, the group performs a 15-minute check dive in a pristine coastal area. This part of the tour allows participants to refresh their snorkeling skills and get comfortable in the water.
The coastal waters are notably clear and peaceful, providing ideal conditions for both beginners and experienced snorkelers. This check ensures everyone is prepared for the main event and helps minimize surprises during the shark-attracting phase.

Following the check dive, the boat navigates 30 minutes to 1 hour toward the shark feeding area. During this time, “chumming”—the process of using organic bait—begins to attract the sharks.
Silvio shares his extensive knowledge about shark ecology and behavior while enjoying a local organic snack with drinks, making the experience both educational and social. The sharks are typically very curious, often passing very close to the boat and spending long periods at the surface.
The sharks’ curiosity means that interactions are often close-up, providing excellent opportunities for observation and photography. Expect that the sharks may take 20 minutes to several hours to appear, depending on conditions.

When the Blue Sharks arrive, they approach cautiously but are very friendly. These sharks are renowned for their curiosity, often passing within arm’s reach. They are considered one of the most beautiful animals in the ocean and are a highlight of the tour.
The main snorkeling activity with the sharks lasts about 30 to 45 minutes, during which participants can observe these graceful creatures floating or swimming close by. The experience of seeing such curious and peaceful sharks in the wild is both exciting and educational.
While Blue Sharks are the primary species observed, there are occasional sightings of Mako Sharks, known as the fastest shark in the ocean. These sightings are less predictable but add an extra layer of thrill for participants.
The tour emphasizes responsible shark watching, maintaining a small group size to avoid stressing the animals and ensuring that interactions are natural and safe. Silvio’s expertise ensures that the experience remains respectful of the sharks’ well-being.

The tour is also suitable for experienced free-divers, as Silvio is a professional free-diver himself. Participants with a free-diving certification can utilize a vertical cable set to a maximum depth of 20 meters and dive alongside a buddy team.
For snorkelers and less experienced participants, the activity remains accessible, with safety instructions and equipment provided. The physical demand is moderate, but basic swimming ability and comfort in open water are recommended.
This activity offers full flexibility with the option to cancel free of charge up to 24 hours in advance, ensuring peace of mind. If canceled due to bad weather, a full refund or alternative date is provided.
Since the tour operates rain or shine within the specified weather constraints, participants should plan accordingly. The small group size and attentiveness of the guides contribute to a safe and enjoyable experience regardless of weather conditions.
The Guided Swimming Experience with Sharks in Portugal on Faial Island stands out as an educational and thrilling opportunity to observe Blue and Mako Sharks up close. The tour’s small group cap of 6 people ensures closer proximity to marine life while maintaining respect for the animals.
