Please how do I get from Beijing to the Glass Bridge by public transport?

You can take a flight from Beijing to ZJJ. It takes about 3 hours for a single trip. Generally, there are three flights serving this route. One departs at 06:25 and the other two departs at 18:25. Then you can take bus line 402 to Ganxi Bridge Station. Getting off the bus and walk to south about 900m to get ZJJ Central Bus Station. You can take a bus from here to Wulingyuan Bus Station and then take a bus from Wulingyuan Station to the Glass Bridge.
