Various tour lengths are available – thank goodness we had more than one day! Even four days was too short in this amazing part of the world. It’s a difficult place to explore on your own so a tour was perfect for us and Orlando’s company suited us perfectly – a reasonable price, an excellent local Aymara guide (Enrique), not luxurious but comfortable accommodations and so many things to see. In this time frame you can experience some altitude issues but Enrique kept a good eye on us. The cost was all inclusive – no hidden surprises.
