Tay Ninh, near the Cambodian border, is home to the headquarters of 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 odd mix of Buddhism, Taoism and Confucianism and Christianity. The Cao Dai Temple at Tay Ninh has been described as a Walt Disney fantasia of the East and has to be seen to be believed.

The trip to Tay Ninh is combined with a visit to the Cu Chi Tunnels. At the height of its existence the tunnel system stretched over 250 km. from Saigon to the Cambodian border and was three levels deep. The network included 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 the visitor a unique experience and a feel of what underground life in the American war was like.
