I will arrive at 8:00 from Guangzhou to Shaoguan Railway Station.

How often buses are leaving from the station to the Danxia mountain?
Can I go there by myself or should I book a guide/join a group? And how often/from where at Danxia buses leave back to the SG Railway Station? If I arrive early in the morning and explore the mountain for 4-5 hours, is it possible to reach a train back to Guangzhou in the same evening?

Thank you for your help! <3
