Rosario and San Bernardo Corals National Natural Park, Marine sanctuary in Caribbean coast, Colombia.
This marine national park sits off Colombia's Caribbean coast and contains coral reefs, islands, and shallow water areas that form interconnected underwater habitats. The environment supports numerous fish species and several varieties of corals that work together to maintain the ecosystem.
The Colombian government created this protected marine area in 1977 to safeguard the coral and marine life from overfishing and damage. About 20 years later, the park expanded to include a larger area and additional islands.
Fishing communities living near the park have shaped how the islands and waters are used over generations through their daily work and traditions. Their presence remains visible in local villages where boats and nets are still part of everyday life.
Reaching the park requires traveling by boat from Cartagena, where tour operators can arrange guided snorkeling and diving trips for visitors of different levels. Plan your visit during drier months when water visibility improves and conditions for water activities are most favorable.
Certain shallow bays in the park glow at night when microscopic organisms in the water undergo a chemical reaction that creates faint light. This rare occurrence is unpredictable, but when it happens, visitors witness an otherworldly display created entirely by nature.
