Casa Chameleon at Las Catalinas, Guanacaste, Costa Rica
Eclectic luxuries meet endless adventures at this heavenly, show-stopping hideaway. Warm Costa Rican kind-heartedness sets the tone for a serene adults-only sojourn, where private villas (strategically stacked along the cliffside) each come with a zero-edge infinity pool, boho-chic interiors and a retractable fourth wall. The main infinity pool, meanwhile, is world-class; and the restaurant, Sentido Norte, absolutely unmissable.
