Vinicunca, also known as Winikunka, mountain of seven colors, rainbow mountain or mountain of colors (Cerro Colorado for the locals), is a mountain in Peru that reaches an altitude of 5,036 meters above sea level. It is located on the way to the snow-capped Ausangate, in the Peruvian Andes, specifically in the Cusco region, between the districts of Cusipata (province of Quispicanchi) and Pitumarca (province of Canchis).

Since the mid-2010s, the mountain has experienced a boom in tourism, attracted by its distinctive stripes of colors, the result of its mineralogical composition on the slopes and summits.

The Red Valley connects Pitumarca with Vinicunca. To get there, leave Cusco and take the Longitudinal Highway of the Southern Peruvian Sierra (PE-3s) to Checacupe, where you turn towards Pitumarca. From this town, you follow a road that passes through several rural communities, such as Ocefina, Japura and Hanchipacha, until you reach Pampa Chiri, the point where the road ends and a hike of approximately 5 kilometers begins to the Vinicunca pass, where you can appreciate the natural formation in the shape of a rainbow.

The entrance to the Rainbow Mountain is from Pitumarca, two hours from Cusco. After a hike by vehicle or on foot through the foothills of the mountain, you can continue on horseback or on foot to the summit.

Research by the Cultural Landscape Office of the Decentralization of the City of Cusco indicates that the colors of the mountain are due to its mineral composition. The pink color comes from red clay and fangolites, while the whitish color is due to quartz sandstone and marls rich in calcium carbonate. The red color is the result of claystones (iron) and clays from the Upper Tertiary, the green color is from phyllites and clays with ferro magnesian, the earthy brown color is from fanglomerate rock with magnesian from the Quaternary era, and the mustard yellow color is from calcareous sandstones rich in sulfide minerals.

On March 30, 2015, the mining company Minquest Peru S.A.C, owned by the Canadian Camino Minerals Corporation, applied to the Geological, Mining and Metallurgical Institute (INGEMMET) for a mining concession in the area known as Red Beds, which covers 400 hectares of the Mountain, overlapping the communities of Chillihuani and Pampachiri, as well as the Ausangate Regional Conservation Area. On March 16, 2018, INGEMMET granted the metallic mining concession title.

In the face of public outrage and rejection, the company relinquished the concession on May 21, but the Regional Government of Cusco indicated that the Ministry of Energy and Mines should take the necessary actions to recover possession of the land. The National Chamber of Tourism (Canatur) expressed concern about the management of Vinicunca, a key component of the country's new tourism offer.
