Jungle Boss Co., Ltd. announced on June 25 that it had completed an expedition leading to the discovery of an entirely new cave in the Ma Da Valley, located within the strictly protected zone of Phong Nha-Ke Bang National Park.

The cave has been named Hang Thắng (Victory Cave) after the local resident who first identified its entrance.

The expedition team reported that information about the cave was provided by a local resident on June 3. Jungle Boss subsequently coordinated with the park’s management board to organise a six-day survey to explore and document the cave.

Preliminary findings show that Victory Cave extends approximately 3,000m, with an average width of around 70m and several chambers exceeding 100m across. The cave features two entrances and splits into two separate branches. Explorers used rope-access techniques to descend about 20m into the cave.

Inside, researchers encountered a vast underground landscape filled with limestone formations created over hundreds of thousands of years. Nearly the entire cave is lined with massive stalactites, including rock columns reaching approximately 50m in height, along with flowstones, stalagmites and other striking geological formations.

One of the expedition's most remarkable discoveries was the abundance of unusually large cave pearls - rare spherical mineral formations produced as water deposits layers of calcite around small particles over long periods. The cave pearls are smooth, white and highly polished, clustered inside numerous natural rock cavities throughout the cave.

According to Jungle Boss, even experienced cave specialists rarely encounter cave pearls of such size and density during underground surveys.

The company said it believes Victory Cave will provide valuable scientific data for geological research while strengthening conservation efforts for the extensive cave network within Phong Nha-Ke Bang National Park. The discovery also further enhances the significance of the UNESCO-listed natural heritage site.

Following the expedition, Jungle Boss proposed incorporating Victory Cave into its existing Ha Ma Da Valley–Tra Ang Cave ecotourism route as part of a two-day, one-night adventure experience. The proposal has received in-principle approval from the management board of Phong Nha-Ke Bang National Park.

If future scientific assessments and conservation requirements are fully met, Victory Cave is expected to become one of Vietnam's newest adventure tourism destinations, supporting sustainable tourism while offering visitors another opportunity to explore the extraordinary underground world of Phong Nha-Ke Bang.
