Bacalar Lagoon, or the Lagoon of the Seven Colors, is a sight to behold. The water becomes crystal clear as hues slowly transform between different shades of turquoise and blue.
You can swim, snorkel, kayak, take a boat ride, or visit the town and wander the Fuerte de San Felipe Bacalar, a fort built in the first half of the 1700s with a rich history.
Wander around secluded bays, laze on quiet beaches, explore underwater caves, climb lofty dunes, plan long picturesque hikes, and go camping among the semi-arid terrain.
The structures sit within a UNESCO-designated Biosphere Reserve, part of a massive forest network that bleeds into Belize and Guatemala, second only to the Amazon in size and age.
The 3,000-year-old site spans a large area. Believed to be the tallest among all the Mayan pyramids, the pyramids in Calakmul soar and have a vast array of carved stone slabs.
Cuernavaca was a prized crop center by both the Aztecs and the Spanish. Plan to visit during the week, when the pace, sights, and restaurants are less busy.
Wander the town's central buildings and landmarks, like the Palacio de Gobierno (governor's palace), Zocalo (the town's main square), or the grand cathedral, built in the 1500s.
