Op Luang National Park

Op Luang National Park is a national park in the Hot District of Chiang Mai Province, Thailand. It is home to a scenic river canyon, waterfalls, and caves. The park's area is 553 square kilometres and is contiguous with Doi Inthanon National Park, as both are in the Thanon Thong Chai Range. Prehistoric paintings and other artefacts have been found in Op Luang National Park. The Doi Pha Chang area has a cliff painting of an elephant. Near Op Luang Canyon, there are more rock paintings, ancient jewellery and tools. Carbon dating has indicated these relics to be about 28,000 years old. In 1991 Op Luang became Thailand's 68th National Park. Waterfalls include Mae Bua Kham, about 50 metres high; Mae Chon, about 80 metres wide and the year-round Mae Tia, about 80 metres high. Thep Thanom is a hot spring in the west of the park. Tham Tong is a granite and limestone cave leading to long tunnels. Tham Tu Pu cave features stalagmites and stalactites. The park features forest types including mixed deciduous, deciduous dipterocarp and evergreen. [Source: Wikipedia]
