Bacalar was founded by the Maya civilization around 415 AD and was known as Siyan Ka'an Bakhalal, meaning "birth of the sky enclosed by reeds.".

The town played a crucial role in the Caste War of Yucatán in the mid-19th century, serving as a Maya rebel stronghold for many years after its capture in 1858.

The Fort of San Felipe Bacalar, built in 1733 to defend against pirates and Maya uprisings, is a major landmark showcasing the town's military history and offers panoramic views of the lagoon.

Bacalar Lagoon, also known as the "Lagoon of Seven Colors," is a shallow freshwater lagoon renowned for its varying shades of blue caused by different depths and sediment compositions.

The Stromatolites, living rock-like structures found in the lagoon, are among the oldest known life forms on Earth and are ecologically important, contributing to the lagoon's oxygen levels.

Bacalar's economy relies significantly on tourism, driven by the lagoon's natural beauty and opportunities for swimming, kayaking, paddleboarding, and boat tours.

The town's population has experienced a steady growth in recent decades due to tourism development and increased interest in the region's natural resources.

Bacalar does not have any UNESCO World Heritage Sites within the immediate town, although the nearby Sian Ka'an Biosphere Reserve is a designated site.

The local culture in Bacalar is a blend of Maya traditions, colonial influences, and contemporary Mexican customs, evident in its cuisine, music, and festivals.

Bacalar celebrates the Festival of San Joaquin in August, a vibrant celebration featuring religious processions, traditional dances, and community gatherings.

The Cenote Azul, a deep sinkhole connected to the lagoon, is a popular spot for diving and swimming, offering a glimpse into the region's underground water systems.

Bacalar's geographical location along the Caribbean coast makes it a crucial point for ecological connectivity and biodiversity preservation in the Yucatan Peninsula.

The municipal government of Bacalar prioritizes sustainable tourism initiatives to protect the lagoon's fragile ecosystem from the negative impacts of increased visitation.

Traditional Maya cuisine, featuring dishes like cochinita pibil and sopa de lima, is widely available in Bacalar, offering visitors a taste of the region's culinary heritage.
