Islas del Rosario is an archipelago located in the Caribbean Sea off the coast of Colombia. Since 1988 the archipelago has been protected as a national park, encompassing a total area of 120,000 km2.

The Islas del Rosario are approximately 100 km (62 mi) from Cartagena, reachable by a 90 minute boat ride. Activities include swimming, fishing, snorkeling, and visiting the aquarium.

Regardless of what mainstream guide books tell you, the cheap tours to Isla del Rosario have nothing to do with appreciating nature nor having a good time on a nice beach. Tours from Cartagena cost between COP$50,000 - 70,000, including boat transport and lunch at Playa Blanca. You will be dropped at an island to visit the aquarium or go snorkeling (for an extra cost), if you don't want to do either, you will be left in a very small area having nothing to do, waiting for the others for an hour.

Food and drink are more expensive than the mainland and expect to pay for bathrooms and change rooms.
