Yun Lai Viewpoint is located about 5 km to the West of Pai town centre above the Chinese Village. See below for a location map. The views are spectacular.
Most visitors rent an automatic motorbike (scooter) when they come to Pai and you will need one of these, or a car, to get here. The journey is easy and relatively safe if taken slowly, from Pai town it should take no more than 15 minutes to get there.
Entry to the viewpoint costs 20 THB a person. I initially objected to paying this when I went, however, I relented and paid the fee when they explained to me that the entrance fee included a free pot of green tea and two cups.
There are toilets here and a few bungalows to rent and not much else. I am not sure that I would want to stay up at the Viewpoint but I did enjoy visiting for half an hour.
