At the secluded Punta Nizuc end of Cancun’s hotel zone, NIZUC Resort & Spa occupies a former presidential retreat between mangroves and the Caribbean. Suites and private villas use dark timber, stone and broad expanses of glass, with many adding plunge pools and sheltered terraces. Six restaurants range from Mexican cooking at Ramona to Asian dishes at Indochine, while the spa includes hydrotherapy and treatment pavilions. Two beaches, several pools and a long arrival pier spread across the low-rise grounds, where reflecting pools and tropical planting soften the resort’s strong architectural lines.
