The Trascău Mountains are crossed by the picturesque Arieș River valley.

The highest elevation in the massif is Dâmbău Peak, at 1,369 metres (4,491 ft).

The northern sector runs for 25 km (16 mi), from the Arieș River, at Buru, to the Rimetea River, with tallest peaks (Iaru, Cireșu, Bedeleu, Prislop, Secu, Geamănu, Tarcău, etc.)

The middle sector continues to the Galda River, with peaks barely reaching 1,100 meters.

The southern sector, which contains the Ciumerna Plateau (with an altitude of 1,200 meters) and the Dâmbău and Piatra Caprii peaks, ends at the Ampoi River.
