Khao Soi Dao Wildlife Sanctuary is a wilderness area, located 70 kilometres north of Chanthaburi. Its ornithological interest lies in it being the western most extent of the Cardamom Mountains stretching into Cambodia that are an important endemic bird area, holding a number of distinct species and forms, many of which in Thailand can only be found at this locality. However, birding at Khao Soi Dao is very tough, with the specialities only readily found at altitude, that basically requires undertaking a major hike and camping.
Two peaks can be contemplated – Khao Soi Dao North (Neua in Thai) and Khao Soi Dao South (Dtai in Thai). At 1,630 metres the southern peak is the higher. Any trek here is best attempted in the drier period from November to March as a trip outside this period risks being washed out in this high rainfall area. In addition to birds, many interesting butterflies can be found at Khao Soi Dao.
From Chanthaburi take Highway 317 north toward Sa Kaew and Soi Dao. About 20 kilometres north of Pong Nam Ron the sanctuary and Khao Soi Dao waterfall are well signposted. If coming from the north or west from Bangkok, Chonburi or Prachinburi, a variety of routes are possible; either via Sa Kaew and then onto Highway 317 southward, or through Tha Takiap on Highway 3259 joining Highway 317 north of Soi Dao.
