Often called the “Switzerland of Thailand”, Khao Kho provides a perfect escape from the sometimes stifling heat of the plains during the hot and dry season, while during Thailand's cool season it offers exotically wintry temperatures. Mulberry orchards here produce a large proportion of the silkworms that produce the material for Thailand's famous loom-woven silk textiles. The lilting local dialect, called Lao Lom or Lao Neua, blends linguistic influences from Northern Thai, from the Khorat dialect and from Phuan, a Lao migrant group once hailing from Laos' XiengKhuang Province.
