A morning drive will take you to Tay Ninh to visit the Cao Dai Holy See in time to watch the mid-day ceremony.

After lunch, you’ll visit the famous Cu Chi tunnels, a Byzantine maze of underground passages, chambers, rooms and booby traps used by both the Vietminh and the Viet Cong to suddenly materialise as if from nowhere, launch a lightning ambush, and vanish equally rapidly. You’ll spend the night in Ho Chi Minh City.

Cao Dai is a ‘new’ religion unique to Vietnam with around a million followers. Both its creed and its architecture are remarkable and exotic. The service lasts about half an hour – the rituals are based upon an eclectic mixture of Catholicism, Hinduism, Buddhism and Taoism. Discreet photography is OK, but shoes must be left outside
