Breakfast at hotel. Morning pick up at hotel and join tour to visit Cu Chi Tunnels, one of the few remaining monuments to the Vietnam War. Beneath the ground lie 200 km of tunnels, dug by hand and inhabited by the forces of the Vietnamese guerillas during the conflict. At its peak, prior to the Tet Offensive in 1968, the tunnel complex was base to almost 10,000 troops. To this day, it remains one of the most impressive examples of how fierce the war used to be. You even can try to crawl some dozens of m on the tunnel underground to have the real experience. Return to Saigon and head to the Reunification Palace, the witness of the fierce Vietnam War ended in 1975. The grand building today is a Museum and Hall of official receptions. Nearby the Palace are the colonial-styled Central Post Office and the Notre Dame Cathedral, built between 1877 and 1883 and one of the city’s major landmarks. Have a walking tour on Nguyen Hue street to take the photos of the Opera House and the Ho Chi Minh Committee (outside). Then continue to the War Remnants Museum, one of the most historically important attractions in the city, where features graphic photographs, military vehicles, and various weapons related to the Vietnam War and in part, the first Indochina War. Overnight in Saigon.
