In a coun­try known for its beau­ti­ful beach­es, Playa Paraí­so (Par­adise Beach), on the island of Cayo Largo del Sur, is one of Cuba’s best. This sub­lime strand of pow­dery white sand and baby blue sea skirts the shel­tered west­ern edge of the island and merges with the equal­ly rav­ish­ing Playa Sire­na.
