Ben Loyal is composed chiefly of granite, and has a distinctive shape due to the four rocky peaks, the highest of which is called An Caisteal. To the north of An Caisteal is the 712 m Sgòr Chaonasaid, to the south is Bheinn Bheag (744 m), which cannot be seen in the photograph opposite, and to the west is the ridge of Sgòr a Chèirich, 644 m at its highest point. The fourth peak in the picture is the 568 m Sgòr Fionnaich.
Ben Loyal is a part of Ben Loyal Estate, owned by the Chamberlain Count Adam Knuth of Knuthenborg, Denmark. Access is by a farm track which approaches from the north, starting at a farm called Ribigill (rented until the early 20th century by the family of British actor David Mitchell.)
