Villa Marilu B&B

Twelve kilometres of turquoise freshwater make up Laguna de Bacalar, and Villa Marilu B&B on Costera 609 occupies the lake's western edge where the shallow shelf shows its clearest colour gradient before the channel deepens.

The property draws a 9.7 rating across 399 reviews, an unusually high score for Bacalar's budget tier. Rooms open toward lake-facing terraces; early mornings reveal the seven-colour banding the lagoon is named for before motorboat traffic disturbs the surface.

Bacalar town centre is a five-minute walk north, with the 17th-century Fuerte de San Felipe and the weekend market on the main square reachable on foot. Chetumal international airport is roughly 45 minutes south by road.
