One of the top attractions in southern Vietnam near the city of Saigon (Ho Chi Minh City), is the Cu Chi Tunnels.  This labyrinth of tunnels and traps was carved out by the Viet Cong during the Vietnam war with the United States.  It was used as a way to ambush approaching US troops, move supplies, deliver information and even as living quarters.  The Cu Chi Tunnels are part of a much larger network that spans much of the southern part of the country.
Today the Cu Chi Tunnels are the most easily accessible part of the greater tunnel network that exists in Vietnam and can be visited on a day trip from Saigon.  These days it’s set up as a proper tourist attraction complete with demonstrations, guided tours, displays and crawlable tunnels.  They’ve even been so kind as to enlarge portions of the tunnels to fit the typical “American physique”.  Although its still quite uncomfortable!

Within the Cu Chi Tunnel complex is an additional treat…The Cu Chi Tunnel Shooting Range.  Despite being fairly expensive it will give you the chance to shoot guns that you rarely come across.  Keep in mind that prices are By-The-Bullet, so it can get expensive quickly…especially if you choose to shoot a machine gun.  Here’s the price list:
