Visit to the Cu Chi Tunnels, an extensive underground network used during the Vietnam War for an interesting look into how people lived and operated underground, with tunnels connecting meeting rooms, kitchens, and even air-raid shelters. Back in the city, explore sights like the Jade Emperor Pagoda, a richly decorated temple, and the Reunification Palace, which has its own piece of history as the former presidential residence. The experience also includes visits to the iconic Notre Dame Cathedral and the Central Post Office, designed by Gustav Eiffel. It’s a day filled with history and culture, giving a well-rounded feel of Ho Chi Minh City.
