The tall silhouettes of the Riu Palace Tres Islas and its neighbour the Riu Oliva Beach can be seen from a great distance (even from the neighbouring island of Lanzarote). It consists of an enormous light sandy-coloured building in the middle of a desert of dunes bordering the turquoise blue ocean. Built in 1974, the 6-storey building houses 368 bedrooms. In between bathing in the heavenly waters of Corralejo dunes beach, why not take a dip in one of the two, 4,176 sq ft and 2,906 sq ft, 3.94 ft-deep fresh water swimming pools, one of which is heated in winter, and which are separated by the bar and open between 8am and 7pm. A small 441 sq ft pool, heated in winter, is available for children. They lie in a pleasant tropical garden with a lawn and palm trees as well as showers, changing booths, parasols, deckchairs, cushions and towels. There is also a small artificial sandy beach with pergola parasols for those who do not wish to journey down to the public beach. You may come across a few cats strolling around here and there; avoid feeding them.
