Gorllwyn is a subsidiary summit of Drygarn Fawr, located on a remote moorland plateau of the Cambrian Mountains. The summit is grassy and is surrounded by peat bog. There is a shelter cairn and a trig point.
To the west is Drygarn Fawr, its large cairns making it a very distinctive feature in an otherwise featureless plateau. Drygarn Fawr is separated from Gorllwyn by the pass of Bwlch y Ddau Faen. To the east the plateau continues towards Y Gamriw.Nuttall, John & Anne (1999). The Mountains of England & Wales - Volume 1: Wales (2nd edition ed.). Milnthorpe, Cumbria: Cicerone. . Radnor Forest lies further to the east.
