Con Co Island: Why is it known as the 'Pearl of the East Sea' of Quang Tri?

Con Co Island is located in the East Sea, belonging to Quang Tri Province – the Central region of Vietnam, with geographical coordinates around 17°10′ N latitude and 107°20′ E longitude. The island lies about 30 km (equivalent to 15–17 nautical miles) from the mainland, holding an important position in both the maritime economy and national defense.

Based on popular starting points, the distance to the island is determined as follows:

• From Cua Viet Port (Gio Linh District): about 17 nautical miles
• From Mui Lay (Vinh Linh District): about 13 nautical miles – the shortest route
• From Cua Tung: about 15 nautical miles

The island has a nearly circular shape, with a modest area of about 2.3 km² (according to data from the Quang Tri Department of Tourism). Formerly an island district, in June 2025, Con Co was upgraded to a special zone directly under Quang Tri Province, opening up many opportunities for tourism and infrastructure development. Currently, the main means of transport to the island is by high-speed boat departing from Cua Viet Port, with a travel time of about 1.5–2 hours. Boat schedules usually operate on Mondays, Tuesdays, Thursdays, and Saturdays, departing in the morning.

The name “pearl of the East Sea” or “green gem” of Con Co Island stems from a special blend of untouched natural beauty, a diverse ecosystem, and profound historical values. Despite its compact area, the island maintains its distinct charm thanks to nearly intact preserved landscapes and a rich ecological environment.

• Rare primeval forest: More than 70% of the island's area is covered by three-canopy tropical forest with rich flora and fauna, making it one of the few places in Vietnam that still retains an almost original natural ecosystem.
• Turquoise sea and diverse coral ecosystem: The waters surrounding the island stand out with clear blue water, a rich marine ecosystem, and beautiful, relatively pristine coral reefs in the Gulf of Tonkin area.
• Unique geology and beaches: The island features basalt rock formations created by volcanic activity alongside natural beaches with white sand, coral fragments, and seashells, creating a very characteristic landscape.
• Special historical value: Beyond its attractive nature, Con Co is also a landmark closely associated with the history of safeguarding island sovereignty and important historical footprints during the resistance war against America.

It is the combination of lush nature, a unique ecological environment, and deep historical significance that makes Con Co Island a compelling destination for travelers who love exploration, island travel, and seeking out the authentic values of Vietnam's nature.

Con Co Island is likened to a “natural museum in the open sea” thanks to its diverse ecosystem, pristine landscapes, and harmonious combination of forests, sea, and unique geological values. Though not overly large, the island gives visitors a sense of closeness to nature and experiences distinct from many other island tourism destinations.

• Lush primeval forest: Most of the island's area is covered by primary tropical forest with rich flora and fauna. Fresh and cool air year-round makes Con Co known as the “green lung” of Quang Tri's sea area.
• Beaches retaining natural features: Areas such as Bai Tranh, Ben Dinh, or Ben Nghe stand out with crystal-clear waters, bright sandy shores, and calm ocean waves. Along the coast are unique basalt rock shelves formed by volcanic activity millions of years ago.
• Lighthouse with panoramic views: From the lighthouse – the highest point on the island, visitors can enjoy a sweeping view of the vast sea and island landscape. This is also an ideal spot to watch stunning sunrises and sunsets over the sea.
• Relaxing space close to nature: With low population density and a well-preserved ecological environment, Con Co Island brings a sense of relaxation, suitable for vacationing, exploring nature, and recharging energy.

The combination of primeval forest, blue ocean, volcanic geology, and characteristic island ambience creates a distinct beauty for Con Co that is both majestic, peaceful, and rich in ecological value.

Con Co Island is one of the areas with the richest and most strictly protected marine ecosystems in the Gulf of Tonkin. The Con Co Marine Reserve (area of over 4,500 ha) includes coral reefs, seagrass beds, and rare biodiversity.

• Coral reefs: Recorded around 113-114 hard coral species belonging to 41 genera. Notable species include red coral, black coral, staghorn coral, branching coral, and table coral. High coral coverage and vibrant colors make it considered one of the most beautiful coral reefs in the region.
• Seaweed and seagrass system: Over 96 species of seaweed and 1 species of seagrass, forming the foundation of the marine food chain.
• Aquatic animals: Hundreds of species of reef fish, crustaceans, benthic organisms, along with rare dolphins and sea turtles.

Thanks to strict conservation efforts (the Reserve was established in 2009), the ecosystem still retains its integrity. Visitors are advised not to touch the coral and not to litter to preserve this “green gem”.

Con Co is not merely a travel destination, but also a place preserving the pristine beauty of Vietnam's sea and islands, from primary forests and colorful coral reefs to historical landmarks that built the resilient spirit of the nation. Setting foot here, you can not only breathe in fresh air and immerse yourself in wild nature, but also have the opportunity to learn about heroic stories associated with the island during the resistance war.
