The sights on the northern tip are ancient Inca sacred sites. The Rock of the Puma, or Titi Kharka, after which the lake is named, is a large formation that will probably look nothing like a puma until the guide points it out. Your reaction will likely either be "Ah, there it is!" or "That's it!" A short distance from the rock is the Inca Table, a low platform fashioned of stone. You may just be imagining a red tint on it, but it was supposedly used for human sacrifices. The Footsteps of the Sun nearby are a set of natural (or supernatural) impressions in rock.
