Terceira

UNESCO heritage, caves, and sea trips from Angra.

Historic and volcanic landscapes on Terceira island

Terceira is home to one of the most striking cities in the entire Atlantic — Angra do Heroísmo, a UNESCO World Heritage Site whose colourful harbourfront, Baroque churches, and carefully preserved cobbled plazas have stood since the 15th century when Angra served as a vital provisioning point for ships crossing from Europe to the Americas. That deep sense of history lingers on every street. Beneath the island's surface, Algar do Carvão is a remarkable volcanic chimney that descends sixty metres into the earth, its walls draped in rare silica crystals and endemic ferns — one of the most unusual underground experiences anywhere in the Azores. On the north coast, the Biscoitos natural lava pools form a series of crystalline basalt basins overlooking the open Atlantic, ideal for swimming when the sea is calm. The island's calendar revolves around the Tourada à Corda, a uniquely Azorean tradition in which the bull is held by a long rope and kept unharmed — a centuries-old summer event celebrated in parishes across the island. Sea trips from Angra's marina, cave tours, whale watching excursions, and guided walks through the Serra de Santa Bárbara highland reserve complete the picture.

Best time to visit: May to September is the best time for warm weather and the full programme of summer festivals, including the Tourada à Corda and Sanjoaninas festivities.

Frequently asked questions about Terceira

What is Angra do Heroísmo known for?
Angra do Heroísmo is a UNESCO World Heritage City — one of the best-preserved historic towns in the Atlantic. Its 15th-century harbour, Baroque churches, and the imposing Fortaleza de São João Baptista make it an exceptional place to walk, eat, and explore on a guided city tour.
What is the Algar do Carvão?
Algar do Carvão is a volcanic lava tube and chimney in Terceira's interior. Visitors descend a narrow pathway into the earth, passing basalt columns and silica crystal formations to reach an underground lake at the bottom. Tours are guided and include a detailed explanation of the island's volcanic geology.
Can I swim in the Biscoitos natural pools?
Yes. The Biscoitos natural pools on Terceira's north coast are popular swimming spots formed by ancient lava flows. The pools are sheltered from the open ocean and the water is clear and calm on most summer days. The area has changing facilities and a snack bar nearby.
How do I get from Angra do Heroísmo to the Algar do Carvão?
The Algar do Carvão is about 15 km from Angra do Heroísmo and requires a car or guided tour to reach. The cave has set visiting hours and a small entrance fee. Combining it with the nearby Furna do Enxofre on Graciosa is only possible as a day trip by ferry.
Are there day trips from Terceira to other islands?
SATA Air Açores and ferry services connect Terceira to other islands, though inter-island day trips are rare. The most practical excursions from Terceira are full-day guided tours of the island itself, covering Algar do Carvão, Biscoitos, the Serreta lighthouse, and Angra do Heroísmo in a single loop.
