	The site is located in southern Vietnam; it was initially designated as a nature reserve in 1986, and designated as a national park in 2002 (BirdLife International 2023, [https://www.protectedplanet.net/10380 WDPA]). The park encompasses a range of high mountains in the northern part of Da Lat plateau. Endemic bird species have been recorded at the site, the most important of which, from a conservation perspective, are Grey-crowned ''Crocias Crocias langbianis'' and ''Garrulax yersini'', which are classified as globally endangered. The site was designated an Important Bird Area in 2002 (BirdLife International 2023).
