Start the day with a visit to Ben Duoc original tunnels located a couple of hours vehicle drive to Tay Minh Province. Arrive around 11:30 am, and this is a perfect time to learn about Cao Daism, its history and have time for endless photos before you watch the followers attending noon mass. Cao Daism is a unique religion combined with Catholicism, Buddhism, Confucianism, Taoism and Islam. Then have lunch in the famous restaurant, continue travelling to Cu Chi tunnels, and visit the Ben Duoc original tunnels. Viet Minh dug the tunnels in 1948 when the French were here, then Viet Cong built the tunnels longer and more complicated than when US Army was in South Vietnam until 1975. It is an impressive underground constructed base. You explore these tunnels with your leader and also accompanied by a Viet Cong guide with local knowledge. Then return to Saigon in the late afternoon.
