After having an interesting experience getting to Sapa with our train catching on fire, we were very ready to relax. We were hoping for something much less hectic than Hanoi and could not have been happier with Sapa. It's a small town, situated in the Hoàng Liên Son Mountains, with the tallest mountain in Vietnam, Mount Fan Si Pan, hovering in the distance at 3,143 meters (10,311 feet).
