Buenaventura is a harbor at the pacific coast in Colombia.
It is widely known as dirty and dangerous city. There is not much reason to visit except to take a boat out of there.
The busstation is close to the center. There are frequent busses to and from Cali (about 4 hours for around COP$10.000).
The docks are on the way in to town. There are boats to most places along the pacific coast.
Near the busstation are some cheap hotels.
