Inside the Furna do Enxofre, on Graciosa Island, a vast volcanic cavern opens beneath the surface, formed by ancient geological forces. At its base rests a still, sulfur-rich lake, while subtle volcanic gases drift through the air, creating a mysterious and otherworldly atmosphere. This remarkable site offers a unique window into the island’s volcanic origins and natural beauty.
