Milk Cave, also known as Stone Milk Cave, is a natural cave located in the Postăvarul Massif, about 3 km from Poiana Brașov. Its name comes from the white mineral deposits known as montmilch ("mountain milk"), which coat the walls and resemble yogurt or milk. Stretching for approximately 175 meters, the cave features a spacious main chamber, limestone formations, and a small bat colony near the entrance. It is a popular destination for nature lovers and cave enthusiasts.
