After you are picked up from  hotel, a short transfer to the pier where you boarding on cruise. Travel to Cu Chi tunnel by speed boat is a truly unique way to observe a different side of Vietnam as you head to the famed tunnel complex where you’ll see an enormous network of underground tunnels used during the Vietnam War. Watch a documentary film then explore the famous fighting tunnels on foot; traps, bunkers, trenches and experience crawling a piece of the underground tunnels. Enjoy lunch before going back to Saigon. Enjoy your own free time the rest of today.
