Customer service! Customer service! Customer service! We reserved with a different company another tour and had to cancel it due to lack of communication and a good customer service. With Viaja Medellin you won't have to worry about it. Sergio and Celene will always be there to take care of you and answer the questions and doubts you may have about how the tours work. They assigned us Natalia as a guide to do the Guatape tour which was just amazing, we had fun and an awesome time from the beggining to the end. Natalia is very knowledgeable about anything you want to know about the Guatape Dam, towns around and Medellin in general. We loved her positive and enthusiastic attitude all the time. We can't wait to come back with more friends. Go to the Guatape Dam and climb the Peñol rock if you think Switzerland is too far and expensive, you won't regret it. Private tours are the best. Thanks to "Viaja Medellin" for the great communication you offer to your clients, it's really appreciated.
