Cat Ba Island

Island in Ha Long Bay

Cat Ba Island, the largest within the 367-island Cat Ba Archipelago, covers an impressive 262.41 square kilometers and forms the southeastern edge of Lan Ha Bay in Northern Vietnam. Known for its dramatic and rugged features reminiscent of the famed Ha Long Bay, Cat Ba Island and its surrounding archipelago have been recognized as a UNESCO Biosphere Reserve since 2004. More recently, in 2023, it became a part of the Ha Long Bay – Cat Ba Archipelago World Heritage Site, underscoring its global ecological and cultural significance. This distinction highlights not only the island’s breathtaking natural beauty but also its importance as a natural habitat, preserving a diverse range of flora and fauna.

The history of Cat Ba Island is rich and storied, intertwining natural history with human civilization. Known historically as “Women’s Island,” local legend says that centuries ago, three women from the Tran Dynasty perished and washed ashore on different beaches of Cat Ba. Locals, moved by their story, built a temple on each beach to honor them, leading to the island’s name. Archaeologically, Cat Ba has proven significant as well, with evidence of human settlement dating back nearly 6,000 years. In 1938, French archaeologists uncovered remnants of the Cai Beo people, linking the island to some of the earliest known cultures in northeastern Vietnam, which thrived from 4,000 to 6,500 years ago.

During the more contemporary history involving conflicts like the Vietnam War, Cat Ba Island played a strategic military role due to its location and terrain. The local population, mostly composed of Viet-Chinese fishermen, frequently utilized the island’s numerous caves as bomb shelters during wartime. These historical sites, including the remarkable three-story Hospital Cave which served both as a bomb-proof hospital and a VC leaders’ safe house until 1975, have since been converted into tourist attractions. Another notable site is Cannon Fort, which offers not only historical artifacts like old bunkers and helicopter landing stations but also panoramic views of the surrounding seascape and the island itself.

Today, Cat Ba Island is a thriving hub of adventure tourism and biodiversity conservation. The island’s infrastructure has developed significantly since the 1990s, improving accessibility and supporting a growing tourism industry that attracts over 350,000 visitors annually. With activities ranging from kayaking and cruising through Lan Ha Bay to exploring numerous caves and trekking in Cat Ba National Park, the island offers a wealth of natural and cultural experiences. Efforts continue to balance tourism growth with environmental sustainability and conservation, ensuring that Cat Ba remains a pristine natural sanctuary for future generations.
