Private Caves Tour with a Geologist

Step into the heart of Terceira Island, Portugal, on a private geology tour led by an expert geologist. Explore the fascinating underground world of Gruta do Natal, a remarkable lava tube with intricate rock formations and a unique volcanic landscape.

Your journey continues to dramatic coastal viewpoints, where, on clear days, you can gaze across the sea to São Jorge and Pico Islands. Along the way, enjoy the flexibility to tailor your experience, whether you wish to sample local cheese or take a refreshing swim in natural ocean pools. Remember to bring a towel and swimsuit if you’re tempted by the water.

The adventure includes a visit to a volcanic chimney, where you’ll marvel at vast chambers formed by ancient eruptions. At the ground steaming area, follow a circular trail to witness sulfur vents and rare flora, all explained in detail by your knowledgeable guide.

This private tour lasts approximately five hours and is designed for groups of up to four people. Hotel pickup and drop-off in Angra or at the main square make your experience seamless. Please note that entrance fees to the caves are not included, and participants should be moderately fit for some low-ceiling passages.
