Location: Sichuan Province, Aba Tibetan Prefecture, Lixian County 四川省 阿坝藏族羌族自治州 理县
The official website www.bipenggou.net is down, not sure if it’s temporary or permanent.
How to get here: 4 hours by bus from Chengdu Chadianzi Bus Station 成都茶店子客运站 to Lixian 理县. Our hotel sent a car and picked us up at the bus station. We stayed in Bipenggou Hotel 毕棚沟宾馆 (info in English and in Chinese), close to the entrance.
Time needed in the scenic area: one day. Shuttle buses run between the entrance and Shanghaizi 上海子. Small open battery buses run from Shanghaizi to the end of the valley at Yanziyan 燕子岩.
It’s best to hike all the way, the hiking path is separate from the road, but the last section (4 kilometers) from Shanghaizi to Yanziyan is a bit annoying, hikers and battery buses share the same rather narrow road.
I strongly recommend staying one day extra in the area, just 20 minutes away from Bipenggou by car lies a lesser known valley with very few tourists. It’s called Liangtaigou 凉台沟. If I had to choose between either Bipenggou or Liangtaigou, but not both, then I would choose Liangtaigou. See this post for more info.
Time of visit: October 2015
