Things to do in  Isla Grande

Deep turquoise water surrounds the archipelago of the Rosario Islands, and lively coral reefs swarm with sealife. This island group off the coast of Colombia is home to mangrove forests and underwater fields of seagrass, with white sandy beaches backed by bright green vegetation. Despite its proximity to Cartagena, you’ll feel like you’ve fully escaped the city with a trip to this biodiverse haven.
