I was hesitant because there were no reviews, but I really wanted to visit Vinicunca, so I applied with some doubt, but I had a great time. I suffered from altitude sickness, so I checked whether there were oxygen cans, and I was able to get quick answers via WhatsApp. And our guide! Humberto was so great that I really wanted to leave a review. He switched between English and Spanish, and his quick and clear explanations, headcount checks, and schedule checks were all professional (thumbs up x3). Breakfast and lunch are both served as buffets. Be sure to drink coca tea. The weather is so unpredictable that it was often hard to see, but we still reached the 5,036m summit. You can rent poles or ride horses back and forth (120 soles round trip) from where the ATVs can't go, and I highly recommend horseback riding if you can afford it. Because of the high altitude, you get out of breath after just 5 steps, but the horse handlers pull the horse with me on it and run (thumbs up). And it's cold! We had experience from a previous trip, so we went armed, so it was okay, but other foreigners struggled a lot with the cold. Gloves are a must. Sunglasses are also essential as you ride through snow and rain. Near the summit, many people bring out llamas wearing sunglasses so you can take pictures with them, but I don't know how much it costs. I don't think it's 10 soles... And they also sell alpaca scarves and snacks. Bring extra money in addition to the 30 soles entrance fee.
