De Seifio, located in Charco del Palo, Spain, offers a unique beach experience on its pristine stretch of coastline. Unlike typical sandy beaches, De Seifio boasts a dramatic volcanic landscape, characterized by its dark, coarse sand and rocky outcrops that add to its natural beauty. The beach's length facilitates a range of activities including sunbathing in its secluded spots, swimming in the crystal-clear waters, and exploring the rock pools teeming with marine life. De Seifio's distinguishing feature is its acceptance of nude sunbathing, making it a popular destination for those seeking a more natural beach experience. However, De Seifio has few amenities, so plan your trip accordingly, although it does have lifeguards on duty to ensure the safety of all beachgoers.
