We mainly went through Hanoi as a gateway to get to Sa Pa and Halong Bay but got plenty of time to explore Hanoi.. It's full of culture and history from the war.. We went to the Hanoi Hilton which was waaaaay more creepy than Alcatraz! There were rooms I didn't even want to go into.. We also went to a women's museum to learn about Vietnamese women's history and also a museum about all the tribes of Vietnam which was really interesting.. They had tribal houses we could go into which was pretty cool to see how different tribes and regions built their houses.. We also went to a water puppet show that dates back about 1000 years, a night market, and beer street where the locals sit on teeny tiny plastic stools on the sidewalk and drink beer..
The city is full of incredible foliage and incredible traffic! There are really no traffic laws from the way it looks.. Tons of cars and motorcycles pack the streets, and you just walk slowly and pray they dodge you..
All in all, we're happy we saw Hanoi.. It's beautiful, and the people there are so kind!
