In the morning you will be driven to to Cao Dai Temple in Tay Ninh.  Tay Ninh, near the Cambodian border, is home to the unique Cao Dai sect, whose patron saints include Joan of Arc, Victor Hugo and Winston Churchill, to name a few. The religion is a hybrid of Buddhism, Taoism, Confucianism and Christianity. The Cao Dai Temple has been described as the Disneyland of the East. The trip to Tay Ninh is combined with a visit to the Cu Chi Tunnels. At its height, the tunnel system stretched over 250km.  Going from Saigon to the Cambodian border, it was three levels deep, including a network of innumerable trap doors, specially constructed living areas, storage facilities, weapons factories, field hospitals, command centers and kitchens. Today, the remaining tunnels have become a major tourist attraction, giving you a unique experience and a feel of what underground life during the U.S.-Vietnam war must have been like.  Then it’s an overnight stay back in HCMC.
