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.

Eugénie, the wife of Napoleon III, created Hôtel du Palais at the end of the 19th century, and it still towers over the northern end of Grand Plage. A visit is well worth the time. In fact, it is essentially a must-see – the interiors and the atmosphere are reminiscent of a bygone era.

Often referred to as the Floating Mosque or Masjid Al-Rahmah, this architectural marvel is known for its stunning white marble exterior. Perched on the edge of the Red Sea, it creates a mesmerising illusion of floating, particularly when lit up at night. This picturesque mosque is not only a popular spot for visitors to admire its beauty but also serves as a significant place of worship for pilgrims travelling to Mecca.
