The biggest city in Vietnam, Ho Chi Minh City is a sprawling feast for all the senses—especially for those who love street food and historical attractions. While Ho Chi Minh City tours can be a great way to make the most of your time here—be it on the back of a scooter, in a US Army jeep, or aboard a riverboat—they’re also a convenient and easy way to get out to the nearby Cu Chi Tunnels or the Mekong Delta, whose floating markets and lush greenery offer a welcome respite from the colorful chaos.
