The private tour to Cu Chi Tunnels and Cao Dai is a great day trip from Ho Chi Minh. Visit Tay Ninh, home of the unique Cao Dai sect which is a mix of Buddhism, Taoism, Confucianism and Christianity. After lunch, visit the famous Cu Chi Tunnels, an amazing underground labyrinth from which the Vietnamese fought during the American/Vietnam war.
