While it is said in National Geographic, the Rough Guide to Colombia and other publications that the Carnaval De Barranquilla is the second largest in the world, following the one in Brazil, I cannot find information on where it occurs in Barranquilla.

Do events follow a known route? Or occur in plazas or public squares? Is there a detailed schedule? Wikipedia says, Feb 6 - 9 for 2016, but that's not enough to be at the right place and time.

Where does one need to go and at what time to have a reasonably good view of main events?
