Cartagena is a port city on Colombia’s Caribbean coast. The walled Old Town, founded in the 16th century, has squares, cobblestone streets and colorful colonial buildings. It was a South American stop on our Caribbean and American cruise. During the fabulous sail into port my head was full of Pablo Escobar and his drug charged career. This was soon forgotten when we hit the streets of the Cartagena, the Colombian capital. A riot of colour and noise filled the senses and left me reeling. The atmosphere was electric, the weather hot and sultry. My only regret for this beautiful and vibrant city was that I didn’t buy an emerald!
