This morning you will visit to the Cu Chi Tunnels. At its height, the tunnel system stretched over 250 kilometers, from Saigon to the Cambodian border, and was three levels deep. The network included innumerable trap doors, specially constructed living areas, storage facilities, weapons factories, field hospitals, command centers and kitchens. Today the remaining tunnels have become a major tourist attraction giving the visitor a unique experience and a feel of what underground life during the U.S.-Vietnam War must have been like. After lunch, you will drive to Vung Tau beach city for short beach escape. Free at your leisure time to relax on the beach. Overnight in Vung Tau.
