Situated at an elevation of 1,900 metres between two mountains on the northern side of Mount Fansipan, Tram Ton is Vietnam’s longest and highest pass. It connects Sapa to Lai Chau, dividing the regions into distinct climatic zones. Tram Ton spreads over 50 kilometres and overlooks unforgettable views of lush peaks, earning it the nickname “Heaven’s Gate”. One can also stop to swim at Silver Waterfall on the way uphill.
