Set in the peaceful pastures of the Sacred Valley lie several enormous circular, terraced depressions in the earth, whose purpose remains uncertain. Although their crop circle-like appearance invites otherworldly hypotheses, we think these unusual Inca ruins were actually a sophisticated crop laboratory designed to study the optimum growing conditions for different species. Continue on to the salt mines of Maras, where seeing the locals mine for salt by hand is truly a unique experience. You will have the option to buy some salt directly from the source, supporting the local economy and making an excellent souvenir. 

Please allow approximately four hours for the entire experience.
