Cartagena is a city of unbridled beauty and boundless energy. Located on Colombia’s Caribbean coast, the walled city is a melting pot of cultures, with a stunning old town that’s a UNESCO World Heritage Site. Colorful houses line the narrow streets, while street vendors and horse-drawn carriages add to the lively atmosphere. The city’s fortifications are a must-see, as is the impressive Castillo San Felipe de Barajas. Be sure to enjoy a cold drink on one of the city’s beautiful beaches, or take a salsa lesson and dance the night away in one of Cartagena’s legendary nightclubs.
