What is Cat Ba Hospital Cave?

Hospital Cave is one of the most unique historical attractions on Cat Ba Island, hidden inside a limestone mountain just outside the town center.

Despite the challenging conditions, daily life continued with structured routines, medical care, and strategic planning taking place within the cave’s walls.
