Shidu (ten ferries) is a spectacular place, which can be reached by taking a sleeper train from beijing which only takes over an hour. You can buy a ticket for 180RMB which is a combo ticket and allows you to do all the activties e.g climbing mountain, glass bridge, go kart, boating etc. It is worth spending the day there and buying the ticket as there is so much you can do. Would highly reccomend to all
