Hi - We recently had Juan Eduardo guide us on the W circuit . He was an excellent guide  - very knowledgable ,helpful and a really nice person .  Juan was always contactable prior to the hike and gave us some good advice about packing etc..he met us for a final catch up before the hike began and organised a private transfer for us at a great rate. We had originally considered doing the hike without a guide but we were all so pleased that we changed our plans and chose Juan - I do not think we could have had a better guide.
