Quick highlights
Arrive early on the night bus or train. If the sky is clear, go straight up Fansipan - the cable car runs from about 8am and clouds usually build later in the day (800,000 VND weekdays, 850,000 VND Saturdays and holidays). If it's cloudy, swap: Cat Cat in the morning and Fansipan tomorrow only if it clears. From the top cable station, climb about 600 steps or take the small funicular to the 3,143m summit marker. Afternoon: walk down to Cat Cat Village, about 2km below town (150,000 VND). Evening in Sapa town - the stone church square and the night market for grilled skewers, grilled rice paper and hot soy milk.
Muong Hoa ValleyTả Van Village
The classic Sapa trek: about 10-12km downhill through the terraces of the Muong Hoa Valley to Lao Chai (Black H'Mong) and Ta Van (Giay). A common way to do it: take a one-way taxi down to Y Linh Ho, walk through the terraces to Lao Chai and Ta Van, and get a car back up from Ta Van in the late afternoon. Start by 8am, go with a local guide, and pay the Lao Chai - Ta Van ticket at the checkpoint. A car or motorbike taxi brings you back up to Sapa for the afternoon bus to Hanoi.
