From the faded yet picturesque port of Caibarién, the pedraplén causeway defies logic. This bold 48km-long roadway built on 49 bridges spans the waves to a string of cayos (islands) scattered across the crystal-clear waters. This archipelago is the perfect tropical idyll. The Cayo Las Brujas and the Cayo Santa Maria are the only ones on the Sabana archipelago with a tourist infrastructure.
