Explore the stunning Ilhéus das Cabras in Terceira Island with this immersive boat tour. Discover volcanic caves, nesting seabirds, and breathtaking views for just $40.49.
Intro
If you’re visiting Terceira Island and crave an experience that combines natural beauty, wildlife, and geology, the Ilhéus das Cabras tour might just be your perfect choice. Priced at around $40.49 per person, it offers a two-hour boat adventure that’s not only scenic but also educational. What sets this tour apart is its focus on protected seabird habitats and volcanic formations, providing a rare glimpse into the Azores’ wild side from the water.
One of the standout features we love is the knowledgeable guide, who shares insights about the island’s geology and birdlife in both English and Portuguese—making the experience accessible to a diverse crowd. Plus, you’ll get the chance to visit some caves only accessible by boat, which adds an element of adventure. A potential consideration is that access to the caves depends on weather conditions and boat type, so if you’re craving a strict itinerary, this might be more flexible than fixed.
Ideal for nature lovers, bird enthusiasts, and those curious about volcanic landscapes, this tour offers a genuine taste of Terceira’s rugged coast and vibrant seabird colonies. It’s particularly suited for travelers who appreciate authentic experiences over cookie-cutter excursions.


The Ilhéus das Cabras are the largest of Terceira’s islets, born from volcanic activity with underwater origins. These rocks aren’t just scenic; they serve as critical nesting grounds for seabirds and are officially protected. As we cruise around the islets, you’ll notice a stunning array of volcanic landforms—fissures, caves, and rocky outcrops—that tell the story of their fiery birth.
The boat tour begins at the Marina de Angra do Heroísmo, a central spot easily reachable for most visitors. Once aboard, the pace is relaxed, giving you ample time to soak in the views while the guide explains the geological processes that created these formations. We loved the way the guide seamlessly switches between English and Portuguese, making sure everyone stays engaged and informed.
Looking for more options in Terceira? Here are some other experiences worth considering.
One of the high points of the tour is exploring the volcanic caves, which are only accessible by boat. Natural structures like Eagles Rays Cave and Cathedrals Cave are named for their distinctive shapes, which you’ll learn about during the trip. These caves are real natural wonders, carved by volcanic activity and now home to many seabirds. However, access to these caves is dependent on weather and sea conditions, so flexibility is key.
The islets’ status as a Protected Area and Important Bird Area reflects their importance for seabird breeding. The presence of species such as the Cory’s Shearwater and Roseate Tern means you’ll likely witness impressive bird activity, especially if you’re lucky with timing. Birdwatchers will find this a highlight, as the guide shares interesting facts about each species and their nesting habits.
Depending on weather conditions, there’s an opportunity to swim in the ocean after exploring the caves. The tour’s flexible nature means you might dip into the Atlantic’s cool waters, adding a refreshing touch to the experience. Just keep in mind that swimming is weather-dependent, so it’s best to come prepared for different conditions.
At just over $40, this tour packs a lot of value. It’s roughly a two-hour excursion, making it ideal for those with limited time but wanting a significant natural experience. The inclusion of a knowledgeable guide, access to caves, and insurance coverage makes it a trustworthy and comprehensive option.
Group size is capped at 25, ensuring a more intimate experience where you can ask questions and get personalized insights. The tour operates in all weather conditions, with cancellations possible only if the weather becomes unsafe—so always check the forecast before heading out.
A noteworthy aspect of the tour is its booking lead time—most travelers book about 11 days in advance, which suggests good availability but also that it’s a popular choice among visitors. Do remember that food and drinks are not included, so planning a snack before or after the trip is advisable.
