Volcanoes in Terceira Island

Explore the unique natural history and geology of Terceira Island 

 

The genesis of the Azores is imprinted in 1766 volcanoes, nine of which are still placidly active. In the subsoil, there are almost 300 known volcanic cavities, in the form of caves, algares and crevices. In the landscape, you'll find dry calderas, crater lakes, fumarolic fields and hot springs. The remains of volcanic activity assume spectacular and easily visited forms, particularly in Terceira.



Algar do Carvão

In the underground world, the highlight is the “Algar do Carvão”, remnants of an old volcanic conduct that dazzles with its spatial immensity. From its vaulted ceiling hang remarkable silica stalactites, the largest in the world. This popular spot is a natural reserve with limited visiting hours, so be sure to plan ahead and put it at the top of your list.

Gruta do Natal

The lava tube of “Gruta do Natal” marvels with the succession of narrow and long corridors and the different shapes and colors that take over the walls, floor and ceiling, transforming the cave into a mystical place.

Furna do Enxofre

On the surface, the “Furnas do Enxofre” (Sulphur Pits) are the eloquent testimony of the power of the Azorean volcanism: the landscape is dominated by fumaroles surrounded by reddish-colored terrain, which contrasts with the green of the mosses and other vegetation. The atmosphere is hot and with a peculiar smell... of sulphur.

Serra do Cume

One of the most popular attractions on Terceira Island, the spectacular Serra do Cume is actually the result of a volcanic eruption. This flat "patchwork" plain was once a volcanic crater, and is now a large stretch of vibrant green pasture land divided by basalt rock walls.  At its highest point, Serra do Cume rises to 545 m (1,788 ft) in height, allowing for wide, panoramic observation and excellent visibility. From one of its faces you can see the city of Praia da Vitória and its bay, and Lajes Air Base. On the other, the view is of the immense plain and its vegetation, beyond the natural stone walls.
