Barú Island serves as the primary access point to the Rosario Islands, connected to the mainland by a scenic bridge from Cartagena.

Direct boat tours from Cartagena often include stops at these highlights, with many departing from the Muelle de La Bodeguita pier. For US travelers, note the time zone is COT (UTC-5), just one hour ahead of Eastern Time, perfect for minimizing jet lag.
