This was one of the things that I really wanted to do before I left Vietnam. I knew about the tunnel system that the Viet Cong fighters had to survive the bombing of south Vietnam and I insisted that we go see them. We were ina group of 35 or more and i was afraid that the tour would be crap but it was anything but. We first saw a Viet Cong propaganda film which was brilliantly biased against the US. Then we headed out to see the tunnels and how the soldiers lived. There was a demonstration of just how small the tunnels really were (some of the tunnels have been enlarged so tourists can go into them) and how cramped the living conditions were. It was incredible just how small and dark and hot it was inside them. While walking around we could see craters the size of swimming pools all around the place made by the US B-52 bombers. It must have been a terrifying time to be alive in Vietnam. Very randomly there is a firing range there where you can buy live rounds for AK47's and go fire a few shots. I didn't do it. I just have no interest in shooting a gun to be honest. The noise out of them is really deafening, even from 15 or 20 metres. I didn't realise how loud they were. our guide told us that only 6 months ago a guy went to shoot some guns but instead of aiming at the proper targets he aimed at his own head and blew his brains out. it was quite a shocking story, all the more shocking that the range is still open after something like that happening. But I guess that is Asia for you. There is no sense of safety around these parts. After a break at the firing range we actually got to go down into the tunnels and travel around 100 metres along them. It was so stuffy and dark in there. I came out the other end dripping in sweat. Some people didn't make it to the end and gave up halfway through it. It was tough getting through it. At one stage I was on all fours shuffling along. And these tunnels have been enlarged 40% for tourists. I can only imagine how small the originals were. A super experience all the same.
