Da Bia hamlet, now Duc Phong, in Tien Phong commune, Da Bac district, was once almost isolated from the outside as the only way to the hamlet was to get a boat ride across the Hoa Binh reservoir. However, as its tourism potential has been unleashed, the hamlet has established itself as one of the most attractive destinations on the tourism map. It has even received the ASEAN Community-Based Tourism Awards in 2019.
