The first thing that everybody comments on about Hanoi is its heavy traffic, and it is true that the mayhem can be intimidating for those with a timid disposition. Nevertheless, enclaves of peace and quiet remain and a number of fascinating bike tours are available. Many operators run trips over the Red River to the rural villages outside Hanoi. Another popular spot, meanwhile, is Tay Ho (or West Lake). Pick up a rental bike at Hanoi Bicycle Collective and saddle up.
