Visit to Nanning and Deitan Falls in Oct

To Detian Fall, there is only one direct bus at 08:30 at Langdong Bus Station. The bus ticket is 60RMB. I think for the water fall, you need one day.
Spending the other day for visiting the city is suggested. Qingxiu Mountain and Guangxi Museum can be arranged on the second day.

Thank You Peter... Now the bus is one way i assume for 60RMB? Does it stop right in front of the waterfall park or we have to walk very far. Same bus will take us back to NN city? What time does the bus leave Detian Fall?

It will arrive at the entrance of the park and the bus leaves from Detian at 15:00 in the afternoon.

Thank you Peter.
What about Bei Hai, is it worthwhile to go there from Nanning ? How long should we stay in Beihai.
