Cu Chi Tunnels Discover one of Vietnam’s most remarkable historical landmarks, an extensive underground network used during the Vietnam War. This complex system once functioned as living quarters, supply routes, hospitals, and command centers. During your visit, you’ll watch an introductory documentary before exploring the site with your guide.
