Bacalar Lagoon

The Laguna de Bacalar — the Lake of Seven Colors — in southern Quintana Roo produces different shades of blue across its 42-kilometre length due to varying depths and dissolved minerals, creating the most visually spectacular inland body of water in Mexico. The town of Bacalar's 18th-century Spanish fort, built to defend against English pirates operating from Belize, overlooks the lagoon from a hilltop that provides the finest panoramic view of the color gradients.
