Traveling in Southeast Asia is one of my favorite adventures. I recently got back from a 3 week trip to Vietnam. The people are amazing, the culture is incredible, the history is fascinating and the landscape is simply stunning. There are so many things to do in Vietnam that 3 weeks just touches the surface. Here is a overview of my adventure so when you plan your next trip, you'll know some of the highlights. Day 1. We arrived at the Hanoi Airport in the evening. Getting through customs was simple thanks to the travel company prearranging the visa's.
