The Graciosa Nature Park, established in 2008, stands out for its unique landscape, geological, environmental and cultural values. Are example of these values, the Furna do Enxofre (cave), which has the largest volcanic dome in Europe, and the Ilhéu da Praia (islet), where nests the most important and diverse colony of seabirds of the Azores and particularly a local endemism known as Hydrobates monteiroi.
Graciosa Island, notorious for its soft and low-relief, has several areas classified within the Natura 2000 network, one Ramsar Site, five priority geosites of Azores UNESCO Global Geopark, four Important Bird and Biodiversity Areas (IBA) and since 2007 that is classified as a Biosphere Reserve within the MAB Programme (Man and the Biosphere) of UNESCO.
The creation of the Nature Park led to the classification of its protected areas, distributed by two Nature Reserves, one Natural Monument, three Protected Areas for the Management of Habitats or Species and two Protected Areas of Resources Management.
Available to its visitors there are the Furna do Enxofre Visitors Centre and a walking trail where you can enjoy a panoramic view of almost the entire southern coast of Graciosa Island and the other islands of the central group.
