Many come to Ho Chi Minh City without missing visit the world-known Cu Chi Tunnel, one of the most famous battle grounds of the Vietnam War and today, the top tourist attraction.
The tunnel, a 75-mile-long underground maze, was originally built in the time of French occupation in the 1940s. It was enlarged during the American presence in the 1960s, providing refuge for Vietnam citizens and defensive fortification against invading forces. Village to village and passing beneath American bases, the tunnel was also a center of community life: in here, people ate, sleep and planned attacks; hospital to heal the sick and welcome the newborn; schools and dating/wedding venues; small theaters for performance, etc..
Having a guide by side is quite necessary for there're lots of stories regarding the war that you won't want to miss. A veteran who lived in the tunnel for years will lead you down the tunnel network and show you around, represent how their people struggled and won the hard battle. You can get through by a 30-meter section of tunnel, but claustrophobic may find it horrible. Put yourself into small ventilation holes to take a picture, which is quite popular with travelers.
Ho Chi Minh City is a hub of war tourism: Reunification Palace and War Remnants Museum are good for further exploration. For culture lovers, Notre Dame Cathedral, Jade Emperor Pagoda, Thien Hau Pagoda, History Museum and Cao Dai Great Temple will not let you down.
