Visit the beautiful caves of Algar do Carvão and look at the extraordinary features of a unique lava tube. Gaze in wonder at endemic plant life, see beautiful silicate stalactites, and more.
Algar Do Carvão
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.
