Full description
Get back to nature and visit the extraordinary lava tube of Algar do Carvão inside the caldera of the Guilherme Moniz volcano, 12 kilometers from Angra do Heroísmo. Travel back in time to when a basalt eruption tore a pre-existing lava flow to begin the process that would lead to the formation of a Strombolian volcano with 2 cones. Observe different geological features, including ferrous deposits and silicate stalactites, and appreciate formations that date back to the origins of the cave. Discover a small pond of rare beauty, and gaze in awe as smoke emerges from the ground. Encounter the unique flora and fauna, including birds that seek refuge inside the cave, and diverse plant life that includes species of molds, arthropods, and other groups.

The tour was excellent! The guide was very enthusiastic about showing us more than just the caves and on way there he stopped at a few more natural attractions which were absolutely stunning! He knew a lot about the island and it’s flora and fauna which made the tour even more interesting. Definitely recommend.

From the moment we were picked up, it was an adventure waiting to happen. We drove through scenic routes to learn more about Terceira, visited a special hidden cave, watched the weather shift through various seasons, and enjoyed the Natal cave, finishing off with the best - Algar do Carvao (lava tube). You'll learn and explore things with Antonio that won't be noticeable or experienced on your own. We'll definitely come back someday and book more tours with the company.

Da unser Schiff die Insel getauscht hatte wegen zu starkem Wind, sind wir schon Montags auf Terceira gewesen und da hatte die Höhle zu. Antonio hatte uns angerufen und uns gefragt ob er uns die Insel mit dem Jeep zeigen soll. Und ich muss sagen, dass war die beste Entscheidung. Wir haben Stellen gesehen, die mit Sicherheit kein anderer von unserem Schiff gesehen hat.
