Lord of the streams; a great river; an ancient forest: all are titles which alternately describe the wonders of Khao Luang National Park, one of the world's most important reserves of various living organisms. Here, the land is high and has formed over centuries into multileveled peaks. Khao Luang, at 1,835 metres above sea level, is the highest peak in the South of Thailand and one of the most picturesque. Curved with deep plains, lush valleys, and tiny streams flowing through forests of rubber, Malabar ironwood, and yang rad (local rubber), Khao Luang is home to rare flora species, such as bang-chang fern (the most ancient fern in the world). Others include raya yok, lam tor noi, and konta singhto (rare flora species). The park also shelters over 327 species of wildlife, including some 157 species of tropical birds alone; all of which are near extinction. Apart from its share of tourists, the park also attracts surveyors, tropical botanists, and wildlife researchers year after year.
