That sounds like a pretty interesting plan! Ili is indeed a beautiful place, with many scenic spots such as the Nalati Grasslands, Sayram Lake, and so on. But if you don’t plan to return with the tour group, you’ll have to plan your next itinerary well, such as arranging accommodation in advance and familiarizing yourself with local transportation. Also, let your family or friends know your plans so they won’t worry. Do you plan to stay in Ili for a while longer? Is there anywhere specific you want to visit??
