A friend and I are going to be travelling around Colombia for roughly 5 weeks from the start of August until the 9th of September, we have some basic ideas about what to see - Bogota, Medellin, Cartagena etc, but I was wondering what people's must sees are, and also if there is anything you would avoid. I have heard the flower festival is worth seeing, and my friend and I would love to do some diving or beach activities on the coast. We are also interested in the coffee plantations, and possibly the Amazon basin also. Any possible routes are much appreciated (we fly into and out of Bogota) and generally any suggestions! the trip is hopefully going to be a good mix of cultural sight seeing, relaxing, a few nights out and some activity based excursions! once again any advice is most welcome.
