Sông Pha
Lâm Sơn is a commune and village of Ninh Sơn District, Ninh Thuận Province, Vietnam.
The commune lies along Highway 27A on the western side of Ninh Thuận Province, about northwest of Phan Rang–Tháp Chàm. It is located at the foot of the scenic Ngoạn Mục Pass.
Lâm Sơn was once connected to the Vietnamese railway network by the now-defunct Da Lat–Thap Cham Railway. The railway heading seaward to Thap Cham was opened in 1919, and the section inland to Da Lat opened in 1932. Due to the mountainous terrain inland from Song Pha, that section used rack rails, the only such railway in Vietnam.
