Nestled within the Bai Tu Long Bay complex, Da Dung Island, located in Dam Ha commune (Quang Ninh province), stands out with its towering limestone formations, diverse marine ecosystem, pristine mangrove forests, and long stretches of white sandy beaches.

Bai Tu Long Bay currently boasts over 600 islands, with Da Dung Island being one of the highlights of this coastal region. Located approximately 12km northeast of Dam Ha commune (formerly Dam Ha district), the island covers an area of ??about 63.3 hectares, encompassing rocky mountains, earthen hills, and pristine forests. Its crescent-shaped beach, nearly 800m long, is an ideal spot for visitors to immerse themselves in the fresh, unspoiled nature.

The rich marine and forest ecosystem, clear blue seawater, and tranquil landscape offer rare value for the development of high-end resort tourism, linked with exploration and conservation.

With the goal of diversifying and developing ecotourism and introducing high-quality tourism products in Bai Tu Long Bay, Quang Ninh province has recently realized this by announcing tour itineraries in Bai Tu Long Bay and itineraries connecting Ha Long Bay and Bai Tu Long Bay; organizing workshops on tourism development in the bay; and introducing high-quality cruise ships to welcome tourists to experience services in the bay.

In June 2025, the People's Committee of Quang Ninh province officially announced Da Dung Island (Dam Ha) as a provincial-level tourist destination. This event contributes to increasing the number of high-quality eco-tourism and resort products, giving tourists more options when visiting Quang Ninh. The area has suitable infrastructure for relaxation, experiential tourism, and organizing events and weddings, catering to high-spending tourists.

This tourism product is oriented towards developing a model for the high-end customer segment. It has the potential to become an ideal destination for those seeking pristine nature and high-quality resort experiences. All development must prioritize the preservation of ecological values, environmental protection, and a harmonious integration of infrastructure and nature.

Da Dung Island is part of Quang Ninh province's regional tourism development plan. Connecting tourist routes from Ao Tien to Da Dung, or from Da Dung to neighboring islands, will create an attractive tourism chain, maximizing the potential already planned by the province. This is a long-term approach that will help exploit natural advantages and create unique tourism products for Quang Ninh.

The recognition of Da Dung Island as a provincial-level ecotourism destination by the Quang Ninh Provincial People's Committee is not only an honor and source of pride for the Party Committee, government, and people of the former Dam Ha district, but also an acknowledgment from all levels and sectors of Quang Ninh province of the beautiful natural landscape, clean climate, and ecological and tourism value of Da Dung Island.

Besides its natural advantages, the Da Dung Island tourist destination also needs improved transportation links and a well-known route map to facilitate visitor access. Furthermore, due to its isolation, the island currently lacks access to the national power grid, has an unstable telecommunications network, and only has a limited supply of fresh water. If it were to accommodate a constant influx of tourists and operate at full capacity, it would face difficulties.

According to the investor of the tourist area on Da Dung Island, tourism products on the island include relaxation, experiential tourism such as being a fisherman, squid fishing... The company is collaborating with neighboring fishing villages, connecting tourist routes to open a center for displaying OCOP products, creating opportunities for economic development for local people.

Along with Co To Island, Ngoc Vung Island, Quan Lan Island..., Da Dung Island is expected to add unique marine ecotourism products and serve as a new model for exploiting the marine economy while preserving the environment, contributing to making Dam Ha a new destination on Quang Ninh's tourism map.

Bai Tu Long Bay cruise - Renowned as one of the most beautiful bays in Southeast Asia, has long been a must-see destination on Vietnam's tourism map. With over 600 islands of varying sizes, numerous beautiful beaches, and a vast system of pristine forests, it is considered a promising area for tourism development.
