The Biscoitos Natural Pools are striking volcanic formations sculpted by ancient lava flows that met the ocean—dating back approximately 4,500 years, originating from Pico Gordo. As the molten AA-type basalt cooled upon contact with seawater, it shaped an intricate coastline of depressions and rocky inlets that now host crystalline, seawater-filled pools—an extraordinary blend of geology and beauty.

Locals adapted the site for bathing in 1969, adding modest infrastructure like ladders, platforms, showers, and cafés, making it one of the island’s most inviting coastal attractions .
