Do I need to book in advance to take a hot air balloon in Tengchong Volcano Park? How to book?

See if there are tickets for attractions on Ctrip, and then search for this volcano park in WeChat to see if there are hot air balloon tickets.

There is no need to book a hot air balloon, just buy a ticket on the spot.

I just went there. During the epidemic, the hot air balloons were not open yet.
