This place is a favourite day trip for tourists. You get to see first hand what it was like to live in the famous Cu Chi Tunnels and learn about their history as they were not only built during the American conflict, but also for the French as well.
There are two types of tunnels. Those widened for us slightly big boned westerners and the original size for locals. Either way they are both just as fun.
If you make it down to Ho Chi Minh City definitely make a day trip to view this amazing feat of engineering and resilience.
