Next, visit the extraordinary Cao Dai Temple in Tay Ninh, often described as a “Walt Disney fantasia of the East.” Its exterior dazzles with bright colours, where multi-shaped dragons twist around columns and sacred symbols decorate every corner. Above the main entrance, the striking image of the all-seeing holy eye represents the unity of the Cao Dai faith. Inside, the temple is just as fascinating: statues of Jesus Christ, Buddha, and the Hindu god Brahma stand side by side, reflecting the religion’s unique blend of beliefs. The vibrant mix of colours, elaborate architecture, and spiritual atmosphere create a setting that feels both beautiful and surreal to Western visitors. A highlight not to be missed is the midday service, when hundreds of worshippers in white robes gather in prayer, offering a moving and unforgettable glimpse into the rituals of this remarkable faith.

After lunch, continue to the legendary Cu Chi Tunnels, one of Vietnam’s must-visit historic sites. This vast underground network once played a crucial role in the Vietnam War, showcasing the ingenuity of guerrilla warfare. Discover the smart design of trap doors, hidden entrances, and living chambers that allowed thousands of fighters to survive bombings and remain undetected. Despite heavy attacks, including 30-ton B-52 bombs, the area resisted capture by 30,000 US troops. Here, you’ll have the unique chance to crawl through a section of the 121-kilometer tunnel system, experiencing first-hand the resilience and determination of the Vietnamese. Learn how guerrillas concealed smoke from their cooking, adapted to life underground for days, and turned the jungle into a stronghold. For an extra thrill, you can even fire real AK-47 rifles at the shooting range. The day ends as we return to Ho Chi Minh City around 6:00–7:00 PM, concluding an unforgettable journey of history and adventure.
