The Small Wild Goose Pagoda is definitely a highlight of Xi'an. It costs 30 yuan to climb it and it is absolutely worth it. At the top of a dark and winding staircase is a trapdoor that you climb out of onto the top viewing platform of the pagoda. It is a really lovely view and a fun way to spend 320 minutes or so. The grounds of the temple are a little unloved, but it adds to the feeling of the place.
