Los Rapidos

Los Rapidos lies on Carretera Xulha near the Bacalar lagoon, described in visitor sources as the Lagoon of Seven Colors, in Quintana Roo, Mexico, a natural lazy river of stunning electric-blue water flowing from the cenote-fed lagoon system. The site is home to stromatolites, layered mineral structures built up by microbial mats, a feature that makes it notable beyond its use as a swimming spot. It is a karst spring-fed watercourse rather than a single sinkhole, part of the same limestone-collapse hydrology that produces the lagoon's many cenotes. This entity documents Los Rapidos specifically as a geological formation, a stromatolite-bearing, cenote-fed lazy river flowing into the Bacalar lagoon.
