Terceira Island
Terceira is the third Azorean island to be found, and it is also one of the largest in the archipelago and one of the most beautiful islands in Portugal. Many people are drawn here by the archipelago's beauty, which mixes amazing nightlife with immense natural beauty, not to mention the archipelago's significant cultural and historical history. Take a stroll around Angra do Herosmo, the former capital of the Azores and now a UNESCO World Heritage Site, even before you put on your hiking boots. Much of the former glory days may still be seen, and you can visit the cathedral, the Igreja da Misericrdia, the Rua Direta, and the nJardim Duque da Terceira, among other places.
Natural wonders of volcanic origin can be found in Terceira's heart. The Gruta do Natal, a lava tube that has solidified throughout the millennia, is located in Algar do Carvo. On Christmas Day, it houses an altar where mass is held. The fumaroles of Furna do Enxofre and, after that, the romantically placed Lagoa da Falc lake are well worth a trip.
