In the morning you will drive to the Cao Dai Temple in Tay Ninh and witness the noon service. The temple is decorated with colorful kites in all shapes and sizes and fitted inside with a series of Buddhist symbols and the sacred all-seeing eye, the symbol of the Cao Dai sect. This religion is a mixture of Buddhism, Taoism, Confucianism and Christianity. Next, you will take a half-day private excursion to the Cu Chi Tunnels. At its height, the tunnel system stretched over 250km, 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 you a unique experience and a feel of what underground life during the U.S.-Vietnam War must have been like. Then relax in your hotel and fall restfully asleep.
