The scenery of Swallow Ditch is good. There are not many tourists in early June. It takes a long time to wait for sightseeing cars. Few tourists in the off-season should allow private cars to drive in, saving mutual waiting time. It is said that the last bus out of the scenic spot at five o'clock, but several other tourists have already waited in the car at 4 o'clock, and the family is embarrassed to stay more. From two o'clock, take the car (1:40 ticket) to 4 o'clock to take the return car, the play time is actually only 1.5 hours. If the off-season tourists are less allowed to drive in by themselves, they can play for at least 2 hours.
