In Saigon there are tons of tour agencies, so you have your share of tours you want to do around the areas. Jamie and i found a 1 day tour that included the Cao Dai Temple and Cu Chi Tunnels for only $7. The bus ride to the temple took a little over 2 hours and we were able to witness the 12 noon service. Very colorful place with a variety of religions all rolled into one(Buddhism/Taoism/Hinduism/Islam/Christianity). Prayer worship is 4 times a day and is usually consisting of older people. The priest that represent the different parts of the religion are dressed in white, yellow, red and blue. You are allowed to watch the service from the balcony and take pictures. This was a nice and interesting stop.
The 2nd leg of the tour was at the Cu Chi tunnels. This is one of the most famous battle grounds of the Vietnam/American war that had about a 75 mile long maze where thousands of fighters and villagers hid and fought back. We first watched a 20 minute video on Cu Chi that consisted of B52's bombing the area, villagers running for cover and communist guerrillas fighting back. After the film we walked into the forest where they had a few boobytraps on display and secret entrances into the tunnels. We were able to go through about 100 meters of the tunnel(the bigger part) and a few places I was on my hand and knees or I kept scraping my shoulders. After the tunnel we wiped off our sweaty bodies and sat for some tea and tapioca root(cassava). You also had the choice to shoot an AK 47 or M60 magnum for a little over $1 a bullet, but I declined. All in all it was an interesting place, but every group was just rushed through so quickly that you didn't have much time to ask questions or get some great snap shots. Well what can you expect for a tour under $10?!
