It's a quieter and more rural village then Ping'An. No cars in the village. There are 3 peaks to hike and also some small villages around. In the village is also a library building where they sometimes dancing and music events and also a school building where you can watch the pupils through the windows. No ATM in Dazhai - but you can change in Wisdom Inn money, also with credit card.
A short hike through Ping'An to the summit takes about 2 hours to complete, depending on fitness. JinKeng is slightly larger so may take more time. It is possible to hike between Ping'An and DaZhai (JinKeng) in about 3 hours, enquire about guides once at either of the villages. Longer hikes spanning more than one day are possible and will allow you to access more beautiful and less touristy areas of the mountain.
