The Island of Terceira, in the Azores, is a true geological gem, shaped by the power of volcanoes over millennia.

One of the standout features of the island is Biscoitos' natural pools. These have been moulded by basaltic lava which, over time, has been shaped by the sea’s waters, creating an ethereal tableau of crystal clear waters encased by dark stones. Here, you also have the chance to taste the distinctive wine produced on this volcanic terrain, where grapes flourish under the influence of mineral-rich soil, resulting in a uniquely flavoured tipple.

However, Terceira Island's true allure lies beneath its surface. By venturing into Gruta do Natal and descending into Algar do Carvão, one of the few volcanoes worldwide open to visitors, you get the chance to delve into Earth's depths and sense the geothermal energy pulsating through its core. These sites bear testament to the volcanic activity that has, over centuries, moulded the landscapes that now mesmerise those who visit.
