Barranquilla is a city on the Caribbean Coast of Colombia. Barranquilla is a cosmopolitan and primarily industrial city, often visited by businessmen of all nationalities; however the main attraction for tourism is its carnival "Carnaval de Barranquilla," that takes place four days before Ash Wednesday. In November of 2003, UNESCO proclaimed it as one of 28 different "masterpieces of the oral and intangible heritage of humanity".
Barranquilla is also called by its residents and Colombians in general "Curramba" (from a language game, in synthesis, Curramba is a reference to "party") and the Golden Gate to Colombia (Puerta de Oro de Colombia), this due to its location on the delta of the Magdalena river, making it the most important commercial sailing port to the Atlantic Ocean for the nation.
Residents are known as "Barranquilleros" and are characterized by their outgoing and friendly attitude and relaxed behavior. This makes the average barranquillero an optimistic and open individual, as well as goal-directed and hard-working.
PLACE TO VISIT
Every year by the end of February or early March (four days before Ash Wednesday), Barranquilla hosts its famous "Carnaval de Barranquilla" (carnival of Barranquilla), a four-day-long celebration in which the true partying spirit of the city is unleashed. Parades, dances, concerts and many cultural manifestations take place all over town.
Barranquilla also houses the beautiful and famous Teatro Amira de la Rosa, the old Customs building-Edificio de la Aduana, that serves as library as well as a museum; the Museum of Gold; and many other great places to visit. There are also a large number of art deco buildings built from the late thirties into the fifties. (See the book Barranquilla-Ciudad Art Deco By Gustavo Garcia)
Another place to visit is "Bocas de Ceniza", where the Magdalena River meets the Atlantic Ocean.
WHAT TO DO
Barranquilla is a small city. Daytime activities are mainly of shopping and eating, but nightlife is active all year round, with bars and nightclubs open from Thursdays to Sundays in most cases. Some of the main party spots in town are Barullo, Seven and Frogg Leggs if you plan to dance.
For a more relaxed environment some options are Luna Negra, Beba Genobeba, Old Times (an 80's retro bar) and some spots known as "estancos": These are basically liquor stores with or without tables, where music is played on weekends. Commonly people gather in these places to drink listening to music from the place itself or from their own car audio systems (in Barranquilla sound restrictions are quite lenient). As well there are magnificent restaurants in the area known as "Washington" such as Naia, Mix were the tourist can experience an elegant, chic night.
Some places are known as "puntos frios" or "mundo de la cerveza" (world of beer), in which you should be able to get beer pretty much any day. There are also small tiendas (convenience stores all over the city).
If you are lucky enough to go during carnivals you will find yourself in a place in which everybody is up to party for entire days with no rest.
HOW TO REACH
Visitors arrive to the city traditionally by plane. The airport "Ernesto Cortissoz" is on the far south side of the city. The fare is usually USD$8-12 to get to the city center by taxi, however car rental services can be arranged from abroad with two main companies: Hertz and National Car Rental.
Buses run by the terminal as well and will get you into the city for $0.55 or less, with the drawback of a significantly less comfortable ride experience.
Barranquilla can also be a connection to other cities of the northern coast of the country, provided the traveler doesn't have a flight connection to anywhere else in Colombia already.
