Furna do Enxofre Visitors Centre

Located in the Natural Monument of Caldeira da Graciosa, the Furna do Enxofre Visitors Centre (CVFE) is the core of the Biosphere Reserve and of the Graciosa Natural Park, while also acting as the entrance to the Furna do Enxofre.

For a better understanding of the volcanic processes that gave origin to the island and, in particular, the Furna do Enxofre and the Caldeira, in the Centre there are several information panels and monitors that demonstrate the detected gas values within the Furna (cave), and also images and documentaries illustrating the natural and cultural values of Graciosa.

With two floors, it is a building that respects the environmental quality in full harmony with the values of geodiversity and biodiversity, and landscape and aesthetic balance.

On the ground floor you will find an exhibition area and on the upper floor, the reception area reserved for the disclosure, awareness and observation of the landscape and the entrance to the Furna (cave).

Going down the staircase, with 183 steps and 37 m high, visitors can see an imposing cave, with 194 m long and 50 m high at its center, which reveals a stunning ceiling with a perfect dome, the largest volcanic dome in Europe, covered by small stalactites and having in its deepest zone, a pond with about 11 m deep. This cave has a fumarolic field, which consists of a fumarole with muddy water and dry gases in the cave floor.
