Your day trip to the laid-back, family-oriented beach retreat in the Rosario Islands offers the Caribbean ideal of platinum sands and crystalline waters. After pickup in Cartagena, take a shared speedboat to Isla Grande, the largest of the islands that form Rosario Islands National Park.
The trip includes a welcome drink and a traditional buffet lunch of fresh fish, coconut rice, fried plantains, and a soft drink. You may also use the beach resort's facilities, kayaks, and other non-motorized water toys, as well as towels and access to the hotel's bathrooms and shower facilities. Snorkeling is also available (rental equipment at your own expense, or bring your own).
Soak up some sunshine and swim in the tranquil waters until it's time to head back to Cartagena. The water can be pretty choppy on the way back to the mainland, so bring a plastic bag to keep your belongings dry.
