The Vale extends south-southwestwards from the coast of the Irish Sea for some 20 miles forming a triangle of low ground bounded on its eastern side by the well-defined scarp of the Clwydian Range and to the west by numerous low hills. The River Clwyd which rises within Clocaenog Forest, southwest of Denbigh, runs the full length of the vale. It is joined by the two major left bank tributaries of the River Clywedog and River Elwy and the smaller right bank tributary of the River Wheeler.

Sarn Helen refers to several stretches of Roman road in Wales. The 160-mile (260 km) route, which follows a meandering course through central Wales, connects Aberconwy in the north with Carmarthen in the west. Despite its length, academic debate continues as to the precise course of the Roman road. Many sections are now used by the modern road network while other parts are still traceable. However, there are sizeable stretches that have been lost and are unidentifiable.

It rises where many streams flow down the slopes of Yr Elen, Carnedd Llewelyn and Carnedd Dafydd to join together in the valley below the cliffs of Ysgolion Duon. It is one of several similarly named streams in Wales. The river flows north-west along Cwm Pen-llafar, with Caseg River joining it near Gerlan, and discharges into the River Ogwen in the heart of Bethesda. Afon Llafar has the same etymology as the River Laver in North Yorkshire, England, with both being derived from Brittonic laβar, meaning "talkative, boastful".
The Afon Gwyrfai is a short river in Gwynedd, Wales. For half of its length it flows through Snowdonia National Park. Exiting Llyn y Gader it flows north through the small village of Rhyd-ddu to enter the southeastern end of Llyn Cwellyn. Downstream of the lake it flows northwest past Betws Garmon, leaving the national park and continues to the southern edge of Waunfawr. It then turns slightly west to flow on to Bontnewydd beyond which it turns slightly south to enter Foryd Bay. The tidal channel within the bay flows north into the western end of the Menai Strait. Principal tributary streams include the Afon Treweunydd which contributes water from the reservoir of Llyn Ffynnon-y-gwas and from the lakes of Llyn Glas, Llyn Coch and Llyn Nadroedd in Cwm Clogwyn immediately west of the summit of Snowdon. The tidal channel of the Gwyrfai within Foryd Bay also accepts the flow of the left bank tributaries, the Afon Foryd, Afon Rhyd and Afon Carrog. The river is shadowed by the line of the Welsh Highland Railway for much of its length, and by which it is crossed four times.
