Cartagena de Noche (Cartagena at night)

Cartagena de Noche

Cartagena is beautiful at night. There's a good article summarizing the travel here on the NY Times website.

Their advice is good. Instead of staying in Bocagrande, find a hotel in Old Town. The Sofitel Santa Clara is a great choice but somewhat pricey for Colombia standards (~$300 a night). Shop around first before booking!
