Colón (Panama Canal), Panama

Some see Colón as the gateway city to the Panama Canal, the engineering wonder linking the Atlantic and Pacific oceans. Others know it as the second-largest duty-free port in all of the Caribbean, and a great base for exploring the canal and Panama’s nearby ecological treasures. On your Carnival cruise to Colón, you’ll see it from all sides — enjoy a side of shop-‘till-you-drop as you spy the brilliant plumage of a toucan in rainforest greenery.
