Pedra de Lume Salt Crater

On Sal Island, the salt pans of Pedra de Lume lie inside the crater of an extinct volcano, reached through a tunnel cut into the rock. The hyper-saline turquoise pools let visitors float weightlessly like in the Dead Sea, surrounded by crystallised white salt and ochre crater walls. Once a thriving salt-mining operation, it is now one of Cape Verde's most unusual attractions.
