Cultural history museum housed in an 18th-century timber dwelling with original Baroque ornamentation. One exhibition is devoted to the graveyard at Gästgivarhagen on the outskirts of town. Some items have been restored and are now exhibited at the museum. There are several themed exhibitions during the year, visit the homepage to find out what exhibition is shown right now.

Once the first free settlement in the Americas, founded by those who escaped slavery during the colonial period, the town of San Basilio de Palenque still stands today, and with it the unique culture of its inhabitants. A portion of the population still speaks palenquero, a creole tongue that emerged from a mix of several European and African languages, now used almost exclusively in San Basilio de Palenque. Music and dance occupy a place of paramount importance in residents' lives, with the Drums and Cultural Expressions Festival held annually in October. The palenque cuisine deserves a separate mention — a culinary tradition upheld by inhabitants of a small Colombian village has garnered international acclaim, with a cookbook written in the town receiving the highest prize at the Gourmand World Cookbook Awards in 2014. If your schedule happens to be too tight for a dedicated day trip (which earns our highest recommendation), try some of the tropical fruit sold by palenqueras in downtown Cartagena. The village was named Masterpiece of the Oral and Intangible Heritage of Humanity by UNESCO in 2005.

Just an hour's boat trip away from Cartagena lie the magnificent Rosario Islands, which belong to Colombia's only underwater natural park (Rosario and San Bernardo Corals National Natural Park). Abundant marine wildlife (including over 50 species of corals) and some of Colombia's best beaches draw in many in search of relaxation and active pursuits such as snorkelling and diving. Isla Grande is best for kayaking through unique mangrove forests and seeing the phosphorescent plankton light up the waters of a brackish lake at night, while Playa Blanca is Cartagena's most spectacular white-sand beach (also reachable by land). It should be said that the company you choose to tour with has the potential to make or break the experience. Low cost tours can mean multiple intermediate stops en route to your destination, as well as unpleasant surprises such as no transfer back to your hotel. Try and choose a trusted company with consistently good reviews, or opt for a private tour. Mind that seas may be rough at certain times of the year, particularly in December and January, when tours on smaller boats may even become dangerous.

Getting to Tortuga Bay involves a hike of about one hour, but the effort is greatly rewarded by a pristine shoreline and spectacular white sand beach. You can try some surfing in the gentle breaks, snorkel in the lagoons to admire colourful reef fish, white-tip sharks, rays and sea turtles, or simply relax on the sand alongside marine iguanas and sally lightfoot crabs.
