Islas del Rosario
Several agents arrange boat tours to Islas del Rosario. A set of small islands out of the coast. Usually the tour include lunch, a visit to an aquarium and a few hours at Playa Blanca. Not included in the price is harbor tax and park entrance (C$14.000 total) and the entrance fee to the aquarium (C$20.000). If you buy your tour at one of the street vendors, don't pay in advance, preferably pay part or all at return in Cartagena. At least one of these tours is to a resort "Coco Liso" which is something like a Colombian butlins. You will be promised a beach, pay a high fee, then disembark a boat after an hour and a half to be greeted with a fairly basic hotel, gimicky pool, and about 6 square feet of beach. Buying a piece of "coral" jewellery from one of the many hawkers, engage them in conversation, and they might lead you to their private beach - quite beautiful, and all the more interesting for having its existence totally denied by the tour operators. The tourist offices in the centre of the old town and a good place to compare the many possible trips to the islands.
