This was a great experience throughout. The professionalism and quality was beyond expectation. It was very difficult for me at 65 years of age. My guide, Carlos was very helpful and was able to get me a horse for a portion of the way, however, at 6' 4", I looked like Don Quixote on his horse.
I can recommend any of the staff that either directly assisted my group, as well as any other guides, chefs and horsemen. Make certain to train beforehand as it is very difficult for older persons to complete, but surely ok if you train. Have fun.
