description Hang Trong Overview
Hang Trống, known in English as Drum Cave, is a notable geological formation located within Hạ Long Bay in the Gulf of Tonkin, Vietnam. The sea cave's Vietnamese name is derived from the acoustic phenomenon created when strong winds blow through its interior caverns and against its stalactite formations, producing a resonant, drum-like booming sound. Hạ Long Bay is recognized as a UNESCO World Heritage site, and its numerous caves, including Hang Trống, are frequently visited by tourists on guided boat tours exploring the region's limestone karst landscape.
