I don't have much time to stay here, so would you recommend me several spots to visit?
There are many beautiful spots worth visiting at the Sun Moon Lake Scenic Area. But if you don't have enough time to visit all of them, I would suggest you visit at least one pagoda, one hiking trail and one temple. The Ci-en Pagoda is the spot that you have to visit. You can enjoy the panoramic view of Sun Moon Lake from the top of the pagoda.
