This half-day adventure on Terceira Island takes you inside some of the most fascinating geological sites around. For just $46.51 per person, you’ll visit a series of volcanic caves, sulfur vents, and scenic natural pools, all with the comfort of air-conditioned transport and the insights of knowledgeable guides. The tour typically lasts around three hours, making it an excellent option for travelers eager to explore natural wonders without a full-day commitment.
What we really appreciate about this experience is how it balances underground exploration with above-ground beauty. The stops at Lagoa das Patas and the natural pools of Biscoitos give a well-rounded taste of the island’s landscape, while the caves incorporate a rare inside look at volcanic activity. The fact that the tour includes personalized guides who are enthusiastic and multilingual makes the experience both educational and fun.
One thing to keep in mind is that the visit to Algar do Carvão, a major highlight, is temporarily closed for reconstruction. As an alternative, the Biscoitos natural pools are included, which still offer stunning scenery and a chance to relax in clear, volcanic waters. This flexibility is helpful but might be a disappointment if Algar do Carvão was a priority.
This tour suits those who love geology, scenic nature, and learning about volcanic landscapes in a relaxed group setting. It’s perfect for travelers who want a comprehensive yet manageable introduction to Terceira’s underground marvels and natural beauty.

A Well-Balanced Introduction to Terceira’s Natural Wonders
When we think about volcanic islands like Terceira, what immediately comes to mind are lava tubes, bubbling sulfur vents, and crystal-clear natural pools. This half-day underground van tour offers just that—an accessible way to see some of the most mesmerizing geological features the island has to offer.
For about $46.51, you get a journey that’s roughly three hours long, packed with stops that showcase the raw power of volcanic activity. The tour also includes pickup and drop-off (a real plus on an island where transportation can be a challenge), a friendly guide, and the chance to snap some fantastic photos of volcanic landscapes and lush natural pools.
Two things stand out for us. First, the expert guides. Travelers raved about how knowledgeable and engaging their guides are, often conducting the tour in multiple languages and sharing stories that bring the landscape to life. Second, the variety of stops—from the secret Lagoa das Patas to the impressive Lava tunnels—means the tour isn’t just about caves; it’s about a broader understanding of how the island’s geology shapes its scenery.
One potential drawback is that the famous Algar do Carvão is temporarily closed for renovations. While this might be disappointing for those hoping to explore inside one of the island’s most iconic volcanic caves, the tour still offers excellent alternatives, like the Biscoitos natural pools, which are equally stunning and perfect for relaxing or taking photos.
This experience is best suited for geology buffs, nature lovers, or curious travelers looking for an easy-to-join, well-organized tour that hits the highlights without a full-day commitment. If you’re traveling with friends or family who appreciate natural scenery and engaging stories, it should be a hit.

What’s on the Itinerary?
Lagoa das Patas: A Hidden Gem
The tour kicks off at Lagoa das Patas, described as a “secret place” by some guides. Here, you can see the stream originating from Serra de Sta Bárbara, and there’s plenty of opportunity to interact with local ducks and birds. It’s a peaceful spot full of life, perfect for snapping some photos or just soaking in the natural calm. Visitors mention that it’s a “full of life and nature,” and a “leisure area” that offers a genuine connection with the local flora and fauna.
Gruta do Natal and Lagoa do Negro
Next, the adventure takes you inside lava tunnels at Gruta do Natal, a highlight for many. You’ll walk through a natural volcanic corridor, feeling the history of molten lava cooling inside the earth. Near this site, the Lagoa do Negro adds a splash of contrasting black water, which makes for a striking scene. This stop isn’t just about the volcano; it’s about understanding how these underground channels form and what they reveal about the island’s volcanic past.
Furnas do Enxofre: Sulfur Geysers
The Furnas do Enxofre offers a close-up look at volcanic gases and fumaroles. Here, you can observe sulfur smoke billowing from several outlets—an active reminder of the island’s volcanic activity. The small pedestrian trail allows you to get close, making this a sensory-rich stop. Visitors have noted the “aggressive volcanic gases” and the high temperatures, so a mask might be handy if you’re sensitive to fumes or want to get closer to the vents.

Biscoitos Natural Pools: A Scenic Finale
Since Algar do Carvão is temporarily closed, the tour now features the natural pools of Biscoitos. These volcanic rock pools filled with crystal-clear, blue waters are arguably one of the most beautiful sights on the island. They’re perfect for a relaxing moment, a quick swim, or just marveling at the volcanic formations. The waters are so clear and inviting, some visitors liken the view to something out of a postcard. It’s a fitting way to end the tour—surrounded by volcanic scenery and feeling the gentle splash of warm water.
Transportation, Guides, and Group Size
The tour uses air-conditioned vehicles, making the sometimes dusty or uneven roads more comfortable. With a maximum of 16 travelers, the group remains intimate enough for personalized attention but lively enough to share stories and laughs. Guides like Amélia and James have received praise for their enthusiasm, professionalism, and multilingual skills, which make the experience engaging and accessible to a diverse group of travelers.
Ticketing and Cost Analysis
While the tour price is $46.51, it’s important to note that entry to the caves costs an additional €15 (roughly $15). This means the total cost includes both transportation and guided commentary, but you need to budget for the cave entrance. Considering the quality of the guides, the variety of sights, and the convenience of pickup, this fee is a reasonable value, especially for those who want to avoid the hassle of self-driving or navigating unfamiliar terrain.
Why Travelers Love This Tour
Reviewers consistently highlight the expert guides who share fascinating stories and answer questions, making the experience more than just sightseeing. The stunning views inside and outside the caves are a common theme, with many describing Algar do Carvão as “overwhelmingly huge” and “magical.” Others appreciated how the stops made the geology come alive, giving a true sense of the island’s volcanic history.
