It is worth the visit. - We really enjoyed the tour. Although it started late due to a public employee strike, that did not affect our itinerary. We had enough time at each stop. Both are very unique places and are worth a visit.

Incredible ! - Hiking the mountain was nice to experience such a high altitude and being so close to Huayna Potosí and see how beautiful is, was such an experience.

Great tour!!1 - Our guide Israel was very helpful and knowledgeable. He answered everyone’s questions and gave a perfect amount of history of both sites.

Unmissable for mountaineers - An unmissable tour for mountaineers, but we must be warned: the altitude of Chacaltaya makes each step a challenge to reach the top, which is more than 5,400 meters. The wind is freezing up there, so be protected. The visit to Vale da Lua is calmer, as it is around 3 thousand meters, but it is unmissable. The geological formation is incredible. The only warning is regarding the sun, which is inclement. Don't forget to bring a hat or cap.

Chacaltaya resort with Buho - No issues at all booking with Buho Tours. Juan was a great guide & the driver carefully made his way up the very poor road to Chacaltaya ‘ghost’ ski resort & we made our way to the top. Be aware that the ‘toilet’ has not been flushed since 2005 & is literally the worst thing ever! Views from the top of the mountain are well worth the huffing to get there (but a fairly easy walk - we are mid fifties & had no problems). Take extra warm clothes obvious. We had a great time

Moon valley and chacaltaya - Amazing landscape!! If you are afraid of heights or have problems breathing in high altitudes, don’t go

Bumpy ride - I won't suggest for anyone who has weak stamina and can't tolerate altitude sickness. Driving all the way to Chacaltaya is very narrow and bumpy and when you arrived to the base line of Chacaltaya, you have to hike it by foot to the top. Valley of the Moon is a different story. The formation of the rocks are unique and I wish we were able to stay longer.

Nice views but lacking information from the guide - The views on this tour were quite nice. The group was nice as well, so overall I had a good time. However I didn't feel like the guide was particularly eager to share any information, and most of the day the group wandered alone in the locations (which is generally not a problem, but then I'd rather not pay for a guided tour).

Terrible - don’t do moon valley tour with them - We were picked up at our hostel, after an hour driving we got way outside of La Paz and we stopped and the tour guide told us moon valley was closed due to flooding of a river blocking the pass. They deliberately didn’t tell us this prior to driving us 1 hour outside of town (they knew the road had been closed for days) so that they could avoid refunding the tour and instead take us on a useless alternative day tour which was a waste of everyone’s time. The day got worse. We went to Chacaltaya mountain as planned, the guide sent a few of us on our way to do a harder walk than the rest of the group. This was extremely irresponsible and dangerous, the walk required crampons and sticks at the minimum, which we did not have. We very easily could have slipped and fallen to our peril. The guide was not there to offer support. We were then driven around aimlessly for the entire afternoon along horrible roads, people got very car sick. We made random and repetitive stops on treacherous roads to look at random useless things. Everyone was fuming and just wanted to go home. We were not given lunch or taken anywhere for lunch despite this being a full day tour, everyone was hungry. When we complained we were patronisingly told “sorry it rained” as if that was the issue. We should have been given the choice as to whether to do the tour or not given they’d known for days the path to moon valley was closed. Instead they drove us to an undisclosed location to take the choice away from us and keep our money too. One slight redeeming quality is we were given half our money back once we went to the office to complain - as far as I’m aware no one else on the tour did because they did not go to the office to complain.

It's a scam! - Worst trip we did in our 3-month tour in South-America. Started with the morning. When the 2 vans are full and we're outside the city, Leo then tells the group that the Moon valley is closed, not reachable by car because of a flood (which they knew for weeks). The tour then changed by visiting a snowy mountain (nobody had clothes or shoes for it, nor gloves). We did a lot of dangerous things in our lives but this was the worst! He "leads" you to a mountain which was so slippery and steap it was actually life threatening. By "leading" i mean he points where to go and then stays behind at a safe place. The 1,5h drive to the mountain was as safe and irresponsible as the hike. No seatbelts and very unsafe. Now that everybody's shoes and socks are wet, we go visit some other places to fill up the time. The guide Leo had 2 stuffed vans to guide, which was way to much to have oversight on everybody on the mountain. We still don't understand why we had to pay 15 bob cash in the busdrive for the entrance of the Moon valley when we didn't even visit it. Also, the 'what to bring' are totally wrong. Here's for you who still choses this company (reminder, don't!): Bring: your lunch (instead of snacks), 1 hiking tenue that you wear, sunscreen and -glasses and especially coca leaves. They don't foresee it and just casually mention that it's best that you had brought some (which indeed would help for the nausia on top of the mountain at 5300m). Tip: if they say to you the Moon valley is closed that day, step out of the car and take a uber home. What a waste of a day, useless... Do not take this company!
