I participated in this tour hoping to go during my stay in Cusco. I was picked up around 4 AM near my hotel, and the tour ended around 3 PM. The guide explained things in both Spanish and English. At the site, I paid about 70 soles one way to go up near the summit by horse or motorcycle. I was told it would take about 1 hour and 20 minutes even walking slowly, but since the ride from Cusco to the trailhead was very bumpy and I felt carsick on the mountain roads, I chose the motorcycle. On the way back, I walked, but I don't think it took even an hour. Some tour participants were suffering from altitude sickness and seemed to be struggling, and another person vomited in the car on the way back. Honestly, it's not a clean road like in Japan for 4 hours one way, and I can't lie and say I was perfectly fine. The tour itself was reasonably priced, and the guide was good, but I think it's something you should seriously consider before going.
