I was wondering if anyone can recommend or give an insight into a shuttle bus service from Hanoi to Sapa? I have heard that there is new highway (since 2014) from Hanoi to Lao Cai, and that a bus can take between 4 to 6 hours to get to Sapa from Hanoi. Has anyone taken a bus via the new highway? if so, how long did it take? I'd like to find the quickest way to get there and avoid taking a night train. We are planning to be there in June.
