Practical

Coordinate from Wikipedia (Lake Bacalar). About 60 km long and 2 km wide, Mexico's second-largest freshwater lake; fed by cenotes; its stromatolites are among the oldest life forms on Earth. A 2015 federal pollution alert followed illegal dumping. Bacalar town's Fuerte de San Felipe was completed in 1729 against pirates. Two-hour boat tours M$250 (Feb 2022); a sailing association runs tours and lessons on the empty north side (Wikivoyage). Inland - a road trip from Chetumal (about 40 km) or Majahual.
