Located over 2.5 miles above sea level in the Andes mountains, Humantay Lake is one of Peru’s most unique natural wonders. With turquoise water you’d expect from the Caribbean and beautiful rugged terrain, it’s a favorite amongst photographers and outdoors enthusiasts. Don’t forget to keep an eye out while hiking to the top as you might see condors flying above. You can hop on a day-long private tour from Cusco or the Sacred Valley to reach the lake, or opt to complete the Salkantay Trek, which will take you from Humantay all the way to Machu Picchu. – Tripadvisor
