Take a bus from Chengdu to Shuimo Ancient Town.

There is a through train at Chadianzi Bus Terminal, which runs twice a day. There is one at 9: 00 a.m. and one at 3: 30 p.m., and the travel time is about 1 hour and 30 minutes. The fare is 28 yuan. You can book tickets two days in advance. The express train can only go to Dujiangyan, and then change to a bus. It takes about 20-3 hours to travel in 25 yuan.

Shuimo accommodation is probably around 80 yuan every night, depending on the type of accommodation. You can book online in advance, or you can look for it later. There are many hotels.

I hope I can help you. Have a nice trip.
