Sapa and Sìn Hồ are two small towns high up on the slopes of the Hoàng Liên Sơn Range, known in French colonial times as the Tonkinese Alps. Sapa is a famous mountain retreat, enormously popular with Vietnamese and foreign tourists. Sìn Hồ, on the other hand, is hardly ever visited by travellers. These two highland towns are connected by lofty mountain passes which afford spectacular views, on a scale not found any where else in Vietnam. Take a motorbike tour from Sapa and spend 2 days on the Sapa - Sin Ho Scenic Loop, you’ll be rewarded with some of the grandest alpine scenery is Southeast Asia.
