My friend and I are traveling to South America for 2 months this summer, beginning in Bogota on July 1. We can spend about a week in Colombia and would like to know what are the best places to see. So far we know we'd like to see cartagena, but are open to suggestions.
Also, we plan to travel mostly by bus, but the bus routes in Colombia seem particularly long. We would appreciate advice about where it is really important to fly. We are on a budget but also don't want to waste all our time on busing.
Thank you in advance!
