Caldeira da Graciosa, protected area in Portugal
Caldeira da Graciosa is a large volcanic crater on the island of Graciosa that looks like a giant green bowl carved into the landscape, with vegetation covering its steep walls. Inside the crater sits a quiet lake with clear water, and from the rim you can see across to the ocean and surrounding terrain.
Caldeira da Graciosa was formed many centuries ago through volcanic activity that built up lava and ash to create the large crater visible today. The site stands as evidence of the island's fiery origin and displays clear signs of past eruptions throughout its landscape.
Caldeira da Graciosa shapes the local identity of Santa Cruz da Graciosa and has been part of the landscape that residents connect with for generations. Farmers use the land surrounding the crater for grazing livestock, making it woven into the daily rhythms of the community.
The crater rim is easily reached by walking trails, and you can follow the Volta à Caldeira path to circle the entire edge while taking in views of lava formations and the sea. Wear comfortable shoes since some paths can be steep or uneven, and watch your footing as you explore the natural features.
Hidden inside the crater is the famous cave Furna do Enxofre, an impressive underground opening with a round shape formed by lava flows that many visitors discover by walking the crater rim from above. Nearby, the lava tube Furna da Maria Encantada offers underground exploration for those interested in volcanic geology.
