Eight Ladies Cave (Hang Tam Co)

Eight Ladies Cave (Hang Tam Co) is a small limestone cave in Phong Nha-Ke Bang National Park in Tan Trach, Bo Trach District, Quang Tri Province. It is known as a war memorial where eight young volunteers died in 1972 when a bomb blocked the cave entrance. Set in dense jungle along historic Road 20 Quyet Thang, the site features a memorial temple and altar inside the cave, attracting visitors interested in history and remembrance within the national park landscape.

Visitors can expect a small, shallow cave set on a forested hillside along Road 20 Quyet Thang inside Phong Nha-Ke Bang National Park. Access involves climbing steep concrete steps to the cave mouth. Inside is a simple memorial altar with incense, statues and plaques commemorating the eight youths. The surroundings are dense jungle and limestone karst. The site is quiet and commemorative, typically visited as a short stop on guided tours of the national park.

On 14 November 1972, eight youth volunteers (four men and four women) who were working on Road 20 Quyet Thang took shelter in the cave during bombing. A bomb struck the cave entrance, blocking it and trapping them inside. The site was later recovered and established as a memorial to their service on this strategic supply route during the war.

The cave is a memorial and place of remembrance honoring youth volunteers. Visitors often offer incense and pay respects. It is maintained as a commemorative site within Phong Nha-Ke Bang National Park and is visited for its historical and educational value.
