Cenote Maravilla is a deep private sinkhole on the Ruta de los Cenotes west of Puerto Morelos, known for a clean vertical light beam, bell-shaped formations, and a dramatic sulfur cloud below the main recreational zone. The dive feels spacious at first, then more cavernous as you work the perimeter above darker water and follow the limestone walls downward. Most teams visit it as an advanced guided cenote dive because access is controlled, buoyancy needs to stay tidy, and the sulfur layer can change visibility and orientation quickly if you descend into it. It suits divers who want strong light effects, a serious overhead-environment mindset, and a quieter inland cenote with more emphasis on geology than casual sightseeing.
