Bus to Zengcheng, Baishui waterfall

hi, I was wondering, is there a line that takes tourists from GZ to the Baishui waterfall, Zengcheng?
If there is, could you please let me know about the approximate schedule and price?


Also, is it possible to prebook the sightseeing bus via wechat? or do I have to pay at the bus stop? In case there is a customer service, where can I find it?
