The beach dunes of the protected Parque Natural de Corralejo stretch along the east coast for about 10km from Corralejo. It can get breezy here, hence the popularity with windsurfers and kite boarders. The locals have applied their ingenuity to the sand-sticking-to-the-suntan-lotion problem by erecting little fortresses of loose stones atop shrub-covered sandy knolls to protect sun-worshippers from the wind. The area is free to enter, and sun lounges and umbrellas are available for hire in front of the luxury hotels.
