The park has an area of 294 square kilometres (114 sq mi) and covers parts of Narathiwat, Yala and Pattani Provinces.

The Budo mountain range is part of the Indo-Malayan equatorial tropical rainforest that has high humidity because of the year-round rainfall that it gets.

The vine leaves are gold in colour, similar to a hardwood tree of the genus Bauhinia, but considerably larger.

Rare animals in the area are rhinoceros, agile gibbons, tapirs, and Sumatran serows.

The most important animal is the spectacled langur that inhabits Southeast Asia, from the south of Myanmar and Thailand all the way to Malaysia and some islands.
