Travelers seeking to escape to a more natural setting often choose Vietnam, but Hanoi offers plenty of a bustle to counterbalance that. Because the tourism industry is so important to the local economy, retailers provide everything you could possibly need, including flip-flops and towels.

For a mere $1, you may purchase not one, not two, but three pairs of flip-flops from the nearby vendors. That should be plenty to keep you nice and cozy during the sweltering Vietnamese summer if you’re traveling with friends or family. Is there anything more you could ask for?
