GLYNCAERYG (GLYN-CAERIG), a township, in the parish of LLANWRIN, hundred of MACHYNLLETH, county of MONTGOMERY, NORTH WALES, 2 miles (N. N. E.) from Machynlleth. The population is returned with the township of Llanwrin. This place forms the south- western portion of the parish, and is situated on the right bank of the Dovey, near the confluence of two streams, each called Dulas, which meet here from opposite directions, and join that river. A winding and beautifully romantic valley, through which one of these streams flows, and separates this township from Merionethshire, commences here. This river has a great variety of character, presenting at intervals foaming cascades and tranquil pools, and is enclosed between lofty and partially wooded precipices, at the foot of which passes the road from Machynlleth to Dolgelley, along the left bank of the river. The road from the former town to Dinasmowddwy also proceeds through the vale of the Dovey, which here exhibits some cheerful corn-fields and meadows, and verdant hills.
