how to do boat trip to leshan buddha. how and where to get boat ticket and entrance ticket?

To appreciate the buddha by boat, you need to get onboard at LS Port and the boat ticket is sold there too. The port can be reached by bus 4, 9, 12 and 13. But please note that by this way, you won't be able to enter the scenic area, hence saving the admission fee.

The entrance ticket are sold at all the entrances. After, you can go to visit the buddha at a close distance.

It's no big difference as for which comes the first. But I personally prefer the climbing first.
