The network of underground walkways, three storeys deep in places, once served as the hideaway of the Viet Cong guerrillas during the Vietnam conflict.
History and war fanatics are likely to be chomping at the bit to visit the site, which spans over 200 kilometres and once connected countless villages and underground communities to the North of Saigon.
Visitors will also have the opportunity to fire M-16s on a specially constructed target range at the Cu Chi site.
Tour guides are dressed as guerrillas to add to the effect while traversing the tunnels, previously only large enough for a 40 kilogram person, which have been widened to accommodate tourists.
Preserved mine fields, bamboo-stake pits and tunnel ramparts are all still intact, with more adventurous visitors able to crawl through some sections at Ben Dinh for maximum effect.
