We arrived into Cartagena by flight at around 11pm. The first thing that hits you is a wall of heat. Cartagena is hot, day and night, and very sunny. For us lily white brits it has taken some getting used to!
I can highly recommend Cartagena, it is a beautiful, walled city that sits directly on the coast and is steeped in history. We explored the city by walking the walls and the narrow streets of the old town. We had a lovely evening watching sunset over the caribbean sea at a bar on top of the walls, see picture below.
