One of Cuba’s postcard-perfect beaches (think palm trees, white sand, and perfect blue water) strings along 20 km (12 miles) of coast. The Brisas Santa Lucía and Club Santa Lucía hotels hold court here. The liveliest activity concentrates in a stretch of sand in front of those hotels, one-tenth the beach’s total length. Outside the standard tourist area, seclusion is yours. If you plan to swim, stick to populated areas. Amenities: food and drink; parking; toilets; water sports. Best for: solitude; snorkeling; sunrise; swimming.
