Bocagrande BeachThe city of Cartagena sits right on the Caribbean coast; however, the beaches in the actual city leave one with much to be desired. Bocagrande is the biggest beach in Cartagena. After living in Miami for two years, I can assure you its beach is far superior to Boca Grande. Alternatives to BocagrandeIf you are craving time in the sun, there are better beaches around Cartagena. Just a 10-minute water taxi ride from Bocagrande, the ride should cost between 10,000 - 20,000 COP each way.
