The source and upper course of the Grab watercourse, including the mill area, are protected as a significant landscape. The Mills of Grab are preserved cultural heritage.
Culture
Grab is included in the protected, annually held carnival procession tradition of the villages below Kamešnica. This tradition is registered under the Croatian intangible cultural heritage code Z-4848. The mačkare carnival customs of the hamlet of Vrabač, which belongs to Grab, were documented in 1966. The St. John the Baptist Parish Church in Grab was built in 1874.
The oldest of the Mills of Grab date from the 17th century, and their construction continued until the 19th century. Bugarins Mill has six Kasikara mills that are still occasionally in operation. Ursićs Mill is the oldest of these mills and was built on one of the sources of the Grab River. Samardžićs Mill is a rural mill complex from the 19th century; its mills are still in operation. Ćosićs Mill has horizontal Kasikara water wheels beneath the arches of the building.
Nature
The Grab watercourse divides shortly after its source, forming ponds and several small waterfalls. The Izvori hiking trail is 11.0 km long. A path along the right bank leads to the source of the Grab watercourse. Around ten bird species and around ten reptile and amphibian species occur in the source area of the Grab watercourse.
