El Rubicón is a flat gravel plain located at the southernmost end of the island of Lanzarote in the Yaiza municipality.
The plain is to the south of the 'Los Ajaches' range of hills and the lava fields of Timanfaya national park.
This probably comes from the colour of the surrounding landscape[1] or perhaps a specific association with Montaña Roja, a red-coloured hill in the area, formed from a dormant volcanic caldera.
The southern end of El Rubicón is now dominated by the tourist resort of Playa Blanca.
This ribbon development extends some nine kilometres along the coast between the 'Faro de Pechiguera' in the west to the Sandos Papagayo hotel in the east.
