A 15-minute hike will take you up Cluj-Napoca's most scenic observation point, the Cetatuia Hill (just across the river from the Old Town). The hill's park-like environment draws in locals and visitors in-the-know, and a plethora of cafes offer sit-down snack and/or drink breaks.

The recently modernised Darwin Entertainment Centre in the heart of the city hosts world-class performances and cultural events. The Darwin Symphony Orchestra appears there regularly, and the centre also hosts major international artists and theatre performances.

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.
