Pai County is located in Mae Hong Son, north of Chiang Mai, about a 3-hour drive from Chiang Mai. Pai County has attracted countless tourists with beautiful rural scenery, because the county is surrounded by mountains, and Pai County is also known as Northern Switzerland. The low consumption here and the lazy atmosphere make it ideal for killing time. Yunlai Observation Deck is located on a hillside behind Yunnan Village next to Pai County. It was originally a tea garden. Due to the high openness of the terrain, it has gradually become a place for tourists to enjoy the panoramic view of Pai County and meet the Chaoyang Cloud Sea. Yunlai has a teahouse opened by the tea garden owner on the viewing platform. The tea leaves are all grown by the back mountain. Its very pleasant to have a cup of tea and snacks while waiting for the sun to jump out of the sea.
