Nguyễn Minh Tâm, deputy director of Củ Chi Tunnels Relic, said that the first three night tours in March had 350 visitors.

After receiving much positive feedback from visitors, the relic site will continue to open ticket sales for three more night tours in April.

Củ Chi Tunnels expects to welcome about 400 visitors for these tours.

According to Tâm, the relic site will continue to keep track of customer feedback and may open more tours in the near future.

The night tour recreates the nightlife of the Củ Chi people in the liberated area during the anti-American resistance war, including activities such as digging tunnels, and milling and pounding rice in the paddy fields.

Through the tour, visitors will gain greater insights into the life and heroic spirit of the Củ Chi people during this period, as well as their role in the fight for both national liberation and unification.

The night tour in Củ Chi will take place from 6:00 pm to 8:40 pm at a price of VNĐ399,000 (US$15.96) per person.

Representatives of the relic site said the tour targets domestic tourists. Currently, domestic tourists visit the tunnels mainly during the day, and the number of visitors is less than 50% of international visitors.

The tunnels welcome an average of 3,000 international visitors per day, and about 1,000 domestic visitors.

Located some 70 kilometres from downtown HCM City, the tunnels served as living quarters and weapon stores of Vietnamese soldiers during the wartime.

More than 120km out of the 250km of the tunnels' length have been preserved for tourism purposes.

In 2016, the historic site was recognised as a special national relic.

Despite repeated attempts by the enemy to destroy the tunnels, they survived and are now maintained as memorials by the Vietnamese Government.

The tunnel system runs in a zig-zag shape underground, with the main route branching out in multiple directions that connect together in certain areas, depending on the terrain.

Some tunnels have structures that include two to three floors. Stairs between floors have trap-doors that lead to secret vaults.

Most foreign travelers like the tours because they have opportunities to learn more about Việt Nam’s history. VNS
