Its opening to visitors at the Thung Ui Cultural Tourism Area in Tay Hoa Lu ward marks a new step in linking archaeological heritage with tourism development.

Beyond its appeal as a tourist destination, Hang Boi provides valuable evidence of early human life in the region, contributing to a deeper understanding of prehistoric communities and their relationship with the natural environment. Integrating archaeological discoveries into tourism also creates opportunities to preserve and promote local heritage in a more accessible way.
