Cusco is a destination that you can visit in it year-round. During the dry season, which lasts from May to October, it is recommended to hike and explore certain mountains. Those mountains include Rainbow Mountain, Humantay Lake or Inca Trail. During each rainy season, from each November to each April, it is often advisable to remain prepared for more occasional rain. If you would like to enjoy consistently good weather and travel at a more relaxed pace with considerably fewer crowds, we recommend visiting during the shoulder seasons, from April to May and September to November.
