Hanoi is hot in the summer time

We're talking 30 to 35 degrees Celsius at a very, very high humidity, so for a walking tour take lots of water and expect to sweat. The sweating is worth it, as the view of street life you get by covering the district on foot is fantastic. The neighborhood has over 1,000 years of history coursing through its meandering street veins, pumping with life representing both the past and present.
