How Many Islands Does Quảng Ninh Have?
Quảng Ninh Province is home to over 2,000 islands, making it Vietnam’s most island-rich region and a paradise for nature lovers. These islands form a breathtaking ecological mosaic divided into Hạ Long Bay, Bái Tử Long Bay, Vân Đồn, Cô Tô, and the northern coastal districts.
In Hạ Long and Bái Tử Long Bays, you’ll find more than 1,969 limestone karst islands, many of which are UNESCO-protected and largely untouched. Iconic spots include Cái Bầu Island, Tuần Châu, and Bản Sen. Moving south, Vân Đồn District boasts 600+ islands like Quan Lạn and Ngọc Vừng, famed for white sands and historical allure, while Cô Tô District shelters 50 islands centered around eco-tourism hubs like Cô Tô Island.
Interestingly, only a small fraction of Quảng Ninh’s islands are inhabited. Larger islands like Cái Bầu (~100 km²) are urbanizing, while countless smaller islets remain pristine, accessible only by private boat. Over the past 20 years, human activities and climate change have caused visible shifts—90% coral loss around Cô Tô and 50% seagrass decline elsewhere.
Today, conservation efforts such as "Hạ Long Bay Free of Plastic" and expanded marine protected areas are underway, but growing tourism (from 4.4M visitors in 2019 to 19M in 2024) keeps pressing the region’s fragile ecosystems. Whether you seek wild adventures or eco-certified tours, understanding Quảng Ninh’s island diversity helps you travel more responsibly — and preserve these wonders for future explorers.

Wild & Untouched: Islands Perfect for Nature Lovers
If you dream of untouched beauty, Quảng Ninh is home to over 2,000 islands, offering pristine landscapes perfect for nature lovers. Bai Tu Long Bay shines with over 2,400 species and hidden caves, while Quan Lan’s white sands and ancient temples tell quiet stories of time.
Co To Island, guarded by permits, offers coral-rich waters and peaceful beaches lined with casuarina forests. Vinh Thuc and Cai Chien remain largely off-the-grid, rewarding eco-travelers with untouched beaches, coastal forests, and authentic fishing tours.
For the best experience, visit from September to November or March to May, when the weather is dry and mild. Respect local conservation rules—your thoughtful travel helps protect these rare ecosystems for generations to come.
