The Rainbow Mountain, also called Montaña de Siete Colores (Mountain of Seven Colors), is located in the Andes in the Cusco region of Peru. It is a unique sight and a definite must-visit location when in Peru.
It was formed by weathering, environmental conditions, and sedimentary deposits over time. The mountain’s unique mineralogy created a marbling effect, with layered hues of gold, lavender, red and turquoise towering into the sky.
The best time to visit is between March and November, or from June to August when blue skies are likely, and the weather is pleasant — making the trail easier to hike.
