Núi Chúa National Park is situated on a wide, mountainous promontory, which projects into the South China Sea between Cam Ranh and Phan Rang bays.

It is one of the few remaining sites in Southeast Asia where the coastal and marine habitats are still in relatively good condition, and it protects an impressive and largely intact biodiversity.

It contains unique semi-arid vegetation and sea turtle nesting beaches, and is located on a promontory bordering a marine park with coral reefs.

This habitat type is only found at sites with hot and dry climates and is under-represented within Vietnam's protected areas network.

The park also supports a number of mammal and bird species of global conservation concern, including the black-shanked douc Pygathrix nigripes, pygmy loris Nycticebus pygmaeus, Asian black bear Ursus thibetanus, sun bear (U. malayanus), large-antlered muntjac Muntiacus vuquangensis and siamese fireback Lophura diardi.

Núi Chúa National Park is now an "island" of natural forest surrounded by agricultural land to the north and west, and sea to the south and east.

The socioeconomic level of many of these people is quite low, especially the inhabitants of the National Park, who experience an average of six months of food shortages per year.

Agricultural products such as rice, banana, cashew nuts, papaya, jackfruit and pineapple can secure the livelihood of the Raglay for a maximum of four months.

Recent studies by Oxfam Great Britain and Kyoto University have highlighted that climate change is already having a profound impact on the intensity of droughts making local livelihoods even more marginal.

As the droughts become more frequent and intense, there has been greater reliance and pressure on certain resources from within the Park, particularly wood for charcoal production, as other forms of livelihoods reliant on good water sources become less viable.
