Imagine walking through the very formations that shaped an island, feeling the raw power of ancient volcanoes beneath your feet. That’s exactly what this Terceira Island Half Day Tour offers—an opportunity to witness the island’s volcanic origins up close and personal.

What we really appreciate about this tour is its balance between stunning natural scenery and accessible adventure.

One standout aspect is the chance to explore the Algar do Carvão, a rare volcano accessible to visitors, which provides a tangible sense of the Earth’s fiery interior.
A potential consideration is that the Algar do Carvão is temporarily closed for renovations, so it’s worth confirming availability before booking.

Your adventure begins at Lagoa das Patas, a tranquil spot often praised for its peaceful atmosphere and lush surroundings. Surrounded by vibrant greenery and a serene lake, this stop offers a perfect photo opportunity and a moment to breathe in the fresh Azorean air. Reviewers have highlighted how this spot provides a quiet escape, ideal for reflecting on the volcanic landscape that shapes the island. With no admission fee, it’s an excellent way to start the tour without additional costs.
The highlight for many is the Gruta do Natal, a lava tube formed by past volcanic activity. This geological formation is an “impressive” sight, giving visitors a chance to walk through a natural tunnel carved by flowing lava. The tour includes entrance tickets, which is great because exploring inside the tube feels like stepping into a prehistoric world. One reviewer mentioned, “It was a unique experience to walk inside a volcano formation,” highlighting how this site offers both educational and awe-inspiring moments. Expect around 25 minutes at this stop, with the opportunity to get close and personal with the island’s volcanic past.
Next, the tour takes you to the Furnas do Enxofre, an area renowned for its fumaroles and sulfur springs. This geothermal site is a real sensory experience—smelling the sulfur fumes and witnessing the emissions from fissures in the ground. Visitors report the environment as “unique,” filled with bubbling hot springs and steaming vents. Though free to visit, it’s a lively reminder of the raw volcanic energy beneath the island’s surface. Here, around 25 minutes is spent, enough to appreciate the power and beauty of geothermal activity.
Finally, the star of the tour is the Algar do Carvão, one of the few accessible volcanoes in the world. It’s a fascinating and rare natural wonder where visitors can descend into the volcano’s interior, exploring its chambers and tunnels. This site is often described as “breathtaking,” and the chance to walk inside a geological formation that’s thousands of years old is truly special. However, it’s important to note that this stop is currently temporarily closed for renovations—so confirming availability before booking is essential.

This tour is perfect for geology enthusiasts or travelers curious about how the island was formed. It’s also well-suited for those who enjoy short, guided excursions with a mix of walkable sites and scenic views.
