Vjetrenica Cave is a karst cave system in southern Bosnia and Herzegovina near the village of Zavala, often described as the largest cave in the country and noted for its rich subterranean biodiversity.

The show section contains chambers and passages with visible speleothems and an underground stream; limited guided tours run into the developed parts of the cave. The site is valued by biologists for numerous endemic cave-dwelling species and by spelunkers for its karst formations.

Exploration and scientific study of Vjetrenica expanded in the 20th century; the cave has been subject to conservation efforts because of its unique fauna and geology. Management has focused on protecting habitats while allowing controlled public access to selected chambers.

The cave sits in the Popovo Polje karst plain in southern Herzegovina, close to the border with Montenegro and near the village of Zavala.

• Visiting access: Access is by guided tours only; parts of the system are closed to independent exploration to protect fragile cave habitats.
• Biological importance: The cave is noted for a high number of subterranean and endemic species, making it important for biospeleology research.

Vjetrenica is in southern Bosnia and Herzegovina near the village of Zavala in the Popovo Polje region. Road access is via regional roads from nearby towns such as Trebinje or Mostar; local signage and guides are recommended for the final approach.
