The island is included in the grounds of Glenborrodale Castle and is part of Sunart SSSI. Ross Rock is located about 200 yd from Risga. Risga has at least 60 crotagans along the east coast, used for fishing. Risga is a rocky island.

History
The name "Risga" is Norse and includes the Old Norse word for island. In 1920–21 some Mesolithic materials were recovered during the excavation of a kitchen. They are now in the Hunterian Museum, University of Glasgow and Kelvingrove Art Gallery and Museum. There is a shell midden, a scheduled monument that is at least 30 by, which is visible as a grass-covered mound. The shell heap is on top of a raised beach, similar to those at Oronsay.
