After hiking the Inca Trail, went on tour while staying in Cusco in 2019; can't remember the company. Picked up early am. Once parked we were given that short speech of what to expect. Hiking in altitude always an adventure, but after the Inca Trail this was second nature. Great views. Main plateau is 16,500 feet according to our guide company. The top of the "general public" crest 17,0010. And yes, the colors are there; though some pics you see on ads have been touched up.

This is a relatively newly discovered site, which was hidden under the perma-ice until quite recently. As far as I've gathered, there is no way to visit independently, without a guide. The drive is a bit exhausting, about 3-4 hours from Cusco centre, so the tours would pick you up very early and return you late in the afternoon. Luckily, most tours include both breakfast (which is very early) and lunch (which is late, so consider bringing a snack if you think you'll need it). The bus will get you fairly close to the site itself, leaving only a short trail and then the way up to the top of the mountain with its stunning 360° view. However, despite the short path, the height makes it a rather strenuous walk. My advice is to leave yourself some time in Cusco to adjust to the altitude before you go on this hike, and perhaps do some easier trekks first. If you're not in the best shape but still wants to enjoy the view at the top, there is the option to be led up on a horse back, or rent a dirt bike or an ATV. Due to the height, you will face both the scorching sun and cold winds, so bring comfortable trekking shoes, a hat, enough water, sunscreen and a warm layer. The guides also recommend a rain jacket, as the weather can be unpredictable and turn in a short span. Note that some tours offer the possibility to continue the treck to the Red Valley. This is at least another 30 min, but seems doable with some time strain. A word of caution: This might well be the most popular site for instagramers, perhaps even more so than Machu Picchu, so be prepared to stand in line in front of the best photographic spots for the opportunity to snap some photos.

The Terra Quechua Peru team not only took us to the Montaña de Colores, but immersed us in a profound cultural experience. Every step to the top was full of discoveries, from the unique flora and fauna to the changes in the landscape that reveal centuries of geological history. I highly recommend this agency not only for their professionalism and knowledge, but for their commitment to sustainable tourism that respects and protects this incredible natural environment.
