Gustavo is a super guide. He was on time for pickup and was engaging and fun to talk with on our trip. We were able to take our time going up and down. Gustavo was supportive and with us every step of the way. I appreciated his focus on health and safety. To me, it was extremely worth it to have a private guide, rather than being on the time of a bus full of people. It was challenging for us, but the accomplishment, views and hot coco were worth every step.
