Cold, but worth visiting
Bogota is a bit of a shock after other towns in colombia... feels very westernized in most parts! Lots of great shopping malls with character, the Candelaria is cute, monserrate is a must-see, and the museums are excellent! never thought I'd see a picasso in Colombia! As far as walking around and exploring, it's harder to do because things are so far apart, and the bus systems aren't especially intuitive, but if you go to the center, there's lots to see, and people are helpful in pointing you around.
Insider Tip:Make sure you have some ajiaco :) it's delicious!
