Terceira Island – Half-Day Geo Tour

Guided tour. Visit Algar do Carvão, Furnas do Enxofre and Gruta do Natal with an expert guide.

Meet your guide and driver to collect you from your hotel and head to the first stop on the tour – the inactive Algar do Carvão. Visit it from the inside and discover its small lake and fascinating geological formations.

Then head to Furnas do Enxofre, a small strip of land with 20 fumaroles that spew white steam into the air. You can also see native flora such as juniper and blueberries from the Azores.

The tour ends with a visit to the Christmas Cave, a cave system known as a lava tube, full of spectacular volcanic formations.
