The road cuts through a mangrove swamp before reaching Cayo Guillermo. The smaller scale (13km²) of this island makes it more relaxed than its larger neighbour, Cayo Coco (370km²). It only has 5km of beaches but offers excellent fishing. From Playa Pilar, the most beautiful beach in the Jardines del Rey archipelago, a catamaran takes visitors to Cayo Media Luna; lying just across the water, it is renowned for its coral reefs.
