If you’re planning a trip to Terceira and have a keen interest in volcanoes, geological wonders, or just want a deep dive into the island’s natural history, this private full-day geology tour offers something special. While it’s not your typical sightseeing jaunt, it’s tailored for those who crave understanding the land beneath their feet as much as the stunning views.
What really draws us to this experience are its expert guidance—a knowledgeable geologist takes you through the fascinating layers of volcanic activity—and the flexibility of a private tour, which means they can adapt the day to your interests. Plus, the itinerary combines scenic vistas, history, and cultural tidbits, making it a well-rounded experience.
On the flip side, a couple of considerations are worth noting. For example, Algar do Carvão, one of the main highlights, is currently closed for renovations and isn’t expected to reopen until 2026. That means some planned stops might require adjustments, and tickets for certain attractions like Algar do Carvão and Gruta do Natal aren’t included in the price. Still, with so many other beautiful spots, this won’t detract much from the overall enjoyment.
This tour is perfect for adventurers and geology enthusiasts, or anyone curious about how Terceira’s landscapes formed over millions of years. It’s also a good choice if you prefer a personalized experience with a knowledgeable guide who can answer all your questions.
