Pedra de Lume Salt Flats

Float in a Volcanic Crater

There are experiences that defy the ordinary, and floating in the salt flats of Pedra de Lume is one of them. Inside an ancient volcanic crater, a few kilometers east of Espargos, a hypersaline lake with pink and crystal-clear waters allows you to float effortlessly, like in the Dead Sea, surrounded by the volcanic rock walls of the crater that filter out any external sound.

Salt was the island's main wealth for centuries — hence its name, Sal — and these salt flats have been in operation since the 19th century. Access is through a tunnel carved into the volcanic rock that suddenly opens into the crater's interior: a natural amphitheater with reddish walls and salt pools stretching as far as the eye can see. The contrast between the darkness of the tunnel and the brightness of the crater is breathtaking.

History and Natural Therapy

The salt flats of Pedra de Lume reached their peak in the early 20th century, exporting tons of salt to West Africa and Brazil. The remains of the extraction machinery, loading ramps, and abandoned colonial buildings give the place an air of industrial archaeology that blends with the natural beauty of the crater.

After floating, it's traditional to apply the saline mud that accumulates on the edges of the pools, a natural treatment rich in minerals that leaves the skin soft. The combination of sun, salt, and silence inside the crater has an almost meditative effect: it's easy to lose track of time floating with your eyes closed while the wind gently whistles at the edge of the volcano.

Pedra de Lume is where geology becomes a spa: a volcanic crater that nature has transformed into the most unusual pool in the Atlantic.
