"Spoken of in almost reverential terms by people that have traveled there, Sa Pa is often seen as a holy grail of destinations in Vietnam . Part of that is because of the environment—a cool mountain town that has lured visitors with its salubrious air and alpine scenery since the early 20th century, when the French constructed facilities for sick officers to recover—as well as its remoteness, located close to the Chinese border in the country’s extreme north. Most visitors come to Sa Pa for the hiking in the nearby valley peppered with minority-ethnic-group villages, or to climb Mount Fansipan, the country's tallest peak, which is located just southwest of the town. Conquering the summit once required a two-to-three-day hike, but now can more easily be reached with the help of a cable car (opened in 2016) that gets you most of the way."
