Azores Nature Tours: Underground Cave Van Tour in Terceira

Angra do Heroísmo, a historic city on Portugal’s Azores archipelago, is the gateway to one of the North Atlantic’s most compelling underground landscapes. Azores Nature Tours invites adventurers on a 3-hour van journey rich with geological wonders across Ilha Terceira. This isn’t just a ride—it’s an immersion into volcanic formations layered beneath the island’s surface, perfect for travelers seeking a compact but intense connection to Azorean nature and history.

The tour’s highlights include the Gruta Natal, a cavern carved from ancient lava flows that showcases delicate rock formations and cool subterranean air. Visitors descend into the lava tubes—long conduits formed by flowing molten rock—offering a striking glimpse into volcanic activity that shaped the island millions of years ago. Another must-see is Furnas de Enxofre, where you encounter sulfurous vents and bubbling thermal spots indicating the island’s geologic vitality.

Beyond the caves themselves, the van tour stops at the natural pools of Biscoitos. These dark volcanic rock basins fill with crystal-clear Atlantic water, offering refreshing swims or a moment of contemplation by the sea. The guided experience blends interpretive storytelling on local geology, volcanic processes, and regional ecology that transforms each stop into a vivid classroom of natural history.

Azores Nature Tours stands out in the Terceira outdoor scene for their seamless combination of comfort and adventure—comfortable transit paired with expert guides ensures accessibility without sacrificing authenticity.
