Inspired by local cenotes, natural swimming holes formed by the collapse of limestone bedrock found in the area, the sanctuary gives a breathtaking and regionally-specific first impression for guests. While the elegant pillars that support the towering porte cochere mimic the angled roots of mangrove trees, a shallow circular pool located in the center of the lobby reflects the sky through the open ceiling above. The 214 guest rooms and suites are housed in low buildings carefully sited on the delicate limestone crust of the peninsula or beachfront.
