Taking a half-day van tour to the caves on Terceira Island offers a fascinating glimpse into the island’s volcanic soul, all in just three hours. From the moment I read about visiting lava tubes like Gruta do Natal and the Furnas do Enxofre, I knew this was a chance to see some of the most intriguing natural formations in the Azores. What makes this experience stand out is not only the diversity of sights—ranging from lush landscapes to dramatic volcanic features—but also the way it combines comfort, accessibility, and local insights into a compact package.
Two things I really appreciate about this tour are the knowledgeable guides, such as André and Amélia, who bring the volcanic landscape to life with stories and practical tips, and the stunning scenery that surprises even in cloudy weather. The views of the island’s rugged coastlines and volcanic craters are genuinely memorable. A small caveat is that the Algar do Carvão—a major highlight—is temporarily closed for renovations, but the replacement visit to the natural pools of Biscoitos still offers plenty of natural beauty. Overall, it’s a superb way to gain a well-rounded snapshot of Terceira’s volcanic geology without breaking the bank.
