The project, themed 'Eco-tourism, Resort and Entertainment in Phong Nha-Ke Bang National Park', is expected to cost VND1,253 billion (US$49.2 million).

It aims to develop the park's main tourism area, which covers 124,832 hectares including the entire national park and part of the adjacent protected forest, which has been assigned to the board for management and protection until 2030.

The project proposal was released along with a plan to enhance and promote investment in tourism development in 2024 at a conference held this past weekend by the provincial People's Committee and the park's management board.

Aside from existing tourism routes and sites, the project outlines 20 new service areas in need of investment, including nine new spots and 11 routes with potential.

The new tourism routes will help visitors explore forests, caves and rivers within the park, as well as historical sites along the Ho Chi Minh Highway in Bo Trach district.

New tourist spots include the Tourism Management and Operations Centre; an eco-tourism spot in the zoo along with a visit to a wildlife rescue area; a high-quality resort at 20 Quyet Thang street; the Nui Doi wildlife breeding and rescue area; a high-class resort in the U Bo U mountain area; eco-tourism sites at Chay Waterfall and Stream 40; and the Ba Tay Hill and Tram Na resort areas.

Meanwhile, the 11 new routes with unique potential will focus on tours exploring Re Forest to the Máy Bay ravine; the Ca Roong and Kling Acuc caves; Vom Cave to Vooc Well; the caves of Chi Huy, Cay Sanh and Bai; the U Bo peak; a spruce forest; Hoa Huong Cave; Khe Ry Cave; the culture and history of Cong-Nong-Binh Cave; the western part along the Ho Chi Minh Highway, inter-province road 562; and the Hung Lau area.

Speaking at the conference, Vice Chairman of the Quang Binh Provincial People's Committee Hoang Xuan Tan emphasised the importance of the project, saying it has affirmed the province's "determination, vision and target orientation" to further improve the management, conservation and sustainable development of Phong Nha-Ke Bang National Park and its value as a world natural heritage site.

He asked that the Phong Nha-Ke Bang National Park Management Board urgently set up a specific detailed plan for the project's implementation.

The board should update, evaluate and detect inadequacies and potential problems to promptly coordinate with relevant authorities to create the best conditions for investors, according to the provincial authority official.

He also assigned the province's Department of Planning and Investment to coordinate with the board to select priority investment items and add them into the province's investment promotion list to call for investments from both domestic and global businesses.

Relevant departments and local authorities should also closely coordinate with the park's management board in implementing the project and continue to promote the region's heritage, he said.

According to a representative from Phong Nha-Ke Bang National Park, the park has become an attractive destination for both domestic and foreign tourists since it was recognised by UNESCO more than 20 years ago.

However, its tourism offerings are not commensurate with its potential, and the quality of some services remains low.

National park Director Pham Hong Thai said he wanted enterprises to invest in new tourism routes and areas to offer visitors the best experience of the world heritage site’s unique landscapes.

The Phong Nha-Ke Bang National Park is aiming to welcome 1.5 million visitors through 2025, with expected revenues of VND500 billion, and three million visitors in 2030, with expected revenues of VND1,500 billion.

The Quang Binh Province development master plan has highlighted Phong Nha-Ke Bang national tourist area as a high-quality tourism centre in Southeast Asia.

The plan also identifies it as one of the province's two main "growth driving centres" in the period 2021-2030.

Phong Nha-Ke Bang National Park was twice recognised as a World Natural Heritage site by UNESCO.

In 2003, UNESCO recognised Phong Nha-Ke Bang National Park according to geological and geomorphological criteria and in 2015, the park was again honoured as a World Natural Heritage site for the second time, based on biodiversity criteria.
