I have used Tours By Locals on many trips. Gustavo was one of the best guides I have had the pleasure of spending time with. He was very attentive to my interest and several times recommended something that I had not even thought of and every time it turned out great. I cannot imagine having anywhere near the amazing experience I had on this trip without Gustavo as my guide. It felt like I was hanging out with a very good friend that was showing me a part of his country he is very proud of. I definitely plan to be back to summit Cotopaxi and experience some of the other wonderful adventures in the surrounding area...with Gustavo once again as my guide and friend.
