In Cartagena, you can participate in the following activities:
- Go to the oldest film festival in Latin America (Cartagena Film Festival).
- Do sports in Simón Bolivar Metropolitan Park.
- Attend the Festival of Flowers (although this festival is more closely associated with Medellín).
However, swimming in the Pacific Ocean would not be applicable, as Cartagena is on the Caribbean coast of Colombia. Therefore, while you can swim in the ocean, it would be the Caribbean Sea rather than the Pacific Ocean.
