When considering a trip to the Azores, the waters surrounding São Jorge Island promise a mix of adventure, discovery, and a touch of history. The Caves Snorkel Tour by boat offers a fantastic way to see the island’s marine environment up close, whether you’re a seasoned snorkeler or trying it for the first time. From tranquil shallow waters to the remnants of a sunken ship, this experience combines natural beauty with a bit of maritime lore.
Two things immediately stand out about this tour: First, the chance to swim in crystal-clear Atlantic waters that are teeming with marine life. Second, the opportunity to explore the remains of the British ship “Iriskay,” sunk in 1945, just off the coast. If you love aquatic adventures paired with a touch of history, this tour makes for a memorable outing.
A consideration worth noting is the two options for snorkeling — from land or by boat — which can impact your comfort level and what you want to get out of the experience. While the boat trip offers scenic views and caves, the land option demands a wetsuit and some swimming effort from the port of Manadas.
This tour is particularly well-suited for travelers who enjoy water activities, are open to light adventure, and want a balanced mix of natural beauty and historical intrigue. It’s also perfect for those who prefer small-group settings, with limited to four participants, ensuring more personalized attention.

Starting Point and Transportation
The tour begins with convenient pickups from three central locations: Hotel São Jorge Garden, Velas, the Velas airport, or another designated spot. This makes logistics simple, especially if you’re staying in Velas or nearby. The small-group format, capped at four participants, means you’ll enjoy a more intimate experience, with plenty of opportunities for questions and personalized attention.
From the pickup point, a brief 5-minute van ride takes you to the harbor in Manadas. This short transfer ensures you’re quickly immersed in the adventure rather than wasting time in transit. For those with their own cars, it’s straightforward to reach the starting locations, and the tour is designed to be flexible in timing — check availability for precise starting times.
The Boat Trip: A scenic voyage
The 1.5-hour boat cruise is more than just transportation. As you leave Velas, you’ll pass through notable sites like Queimada and Urzelina, providing stunning views of São Jorge’s volcanic slopes. The coastline is dotted with volcanic cavities, and the boat offers a perspective you can’t get from land, revealing dramatic cliffs, caves, and natural sculptures carved by the sea.
Most reviewers rave about the views from the boat. One noted, “The scenery from the vessel is breathtaking, with volcanic formations and caves that look like they belong to another world.” The boat trip includes stops at volcanic caves, where you can dip into the water and, if you wish, swim inside the caves themselves — a rare opportunity that adds an extra layer of adventure.
Snorkeling from Land vs. Boat
From land, the snorkeling is located at Baía do Negro in Manadas, at a shallow depth of about 2-3 meters. Here, you’ll need to wear a wetsuit (which is provided), and you’ll swim approximately 150 meters from the port. This option demands more effort but rewards you with close-up views of the shipwreck debris scattered on the seabed.
From the boat, you’ll get the chance to snorkel in different spots, including the volcanic cavities — caves that are perfect for exploring underwater tunnels. The boat option is ideal if you prefer to relax and enjoy the scenery with less physical effort, plus it offers the thrill of swimming in volcanic caves.

One of the main highlights is the chance to see the remains of the “Iriskay,” a ship that sank off São Jorge in 1945. The wreck sits at a depth of just 2-3 meters, making it accessible for snorkelers of most skill levels. Local residents cleaned the wreck after the sinking, and today, some pieces are still scattered on the seabed, creating a fascinating underwater museum.
Many reviews mention how surprisingly clear the water is around the wreck, making it easy to see the rusted structure and scattered debris. One snorkeler described the experience as “like swimming through history in a transparent aquarium,” which underscores how accessible and intriguing this site is.
