Enjoy convenient pickup at your hotel in central Cartagena in the early morning, then travel approximately an hour to the coastal town of Barú in a comfortable tour vehicle.
Upon arrival, transfer to a speedboat bound for the Rosario Islands, where you'll spend an hour snorkeling around the coral reefs. Refuel with some water and local fruits before continuing to Cholon to visit the unspoiled Playa Azul. Beachside massages are available; you're welcome to visit the local bars for drinks (own expense).
Next stop is lunch at Playa Blanca. Following a hearty meal, spend the afternoon swinging in the hammocks, lounging on the beach, or sipping tropical drinks from the bar.
You'll be dropped off back at your Cartagena hotel around 6:30pm.
