The second option is the modern system of TransMilenio, opened in 2000 and expanded significantly since then with new stations and units. We tried it almost unintentionally, because we took a bus that took us to La Candelaria thinking that he would leave us in the downtown area that bears the same name, but it turned out that there is a neighborhood on the outskirts of the city that is called the same and we went to take it by sack. Then we took a feeder - free blue buses that take you to the main exits of the TransMilenio - that left us at one of the main stations of the TransMilenio. From there we planted downtown in less than 15 minutes.
The ticket leaves by 1,600 pesos and its operation is very similar to that of the Metro. It has different lines and the articulated bus moves through a network of double lanes - there is a TransMilenio Express that uses the fast lane - reserved for service only. The interior is quite modern and reminded me a lot of the service of Luas from Dublin.
I advise you as the best of the three options to move around the city if you connect areas that suit you.
During the day we moved by bus but at night, when we were leaving and returning from the march, the taxi is what I whistled. The taxis in Bogotá they are yellow and all have a taximeter that prevented us from having to bargain prices before getting on, as I had to do in Ecuador, Peru or, sometimes, in Argentina.
Of course, as always, note that the driver has the license in sight when you get on because there are illegal taxi drivers, but come on, as everywhere. The truth is that almost everyone who touched us was very nice and advised us places to visit both in the city and in the rest of the country. There was only one who did not like the way to close the door that, according to him, we had all the Spaniards and the colleague did not speak to us all the way. There is work.
Taxi prices are more or less decent but, as usual, compared to buses or TransMilenio is much more expensive. However, it is worth the expense if you move around the city late in the morning or are loaded with your backpack.
To get to the airport there is a bus that makes the journey that leaves much cheaper than the taxi, which pays a fee for entering the airport and the fare does not fall from the 27,000 Colombian pesos.
Nothing like getting on a bus in Bogotá to take your morning hangover after a good farra. They drive like crazy!
