Rainbow Mountain (Vinicunca)

Rainbow Mountain, or Vinicunca, offers one of Peru's most striking landscapes, with mineral stripes of red, yellow, green, and pink revealed only after the glacier cap that once covered it melted in the early 2010s. Largely unknown to outsiders until mass tourism arrived in the mid-2010s, the mountain now draws large crowds daily in peak season, reflecting its rapid transformation from a hidden gem to a major tourist destination.
