The Afon Mawddach is a river in Gwynedd, Wales, which has its source in a wide area SH820300 north of Dduallt in Snowdonia. It is 28 miles (45 km) in length, and is much branched; many of the significant tributaries are of a similar size to the main river. The catchment area is bounded to the east by the Aran Fawddwy massif and to the west and north by the Harlech dome which forms a watershed just south of Llyn Trawsfynydd.

The Vale of Clwyd is a tract of low-lying ground in the county of Denbighshire in northeast Wales. 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.

The River Elwy is a river in Wales forming a tributary to the River Clwyd. The source of the river is sometimes said to be on the northern flank of Moel Seisiog, south-east of Llanrwst, at Ordnance Survey grid reference SH 853593. However the river only receives the name Elwy at the village of Llangernyw, where three rivers, Afon Cledwen, Afon Collen and Afon Gallen, meet to form the Elwy. It flows eastwards through Llanfair Talhaiarn and a few miles downstream from this village it is joined by a tributary, the River Aled which has its source in Llyn Aled.

Drum is a summit in the Carneddau mountains in north Wales, 2 km north-east of Foel-fras. It is 771 m (2,526 ft) high. It is also known as Carnedd Penyborth-Goch.
Carnedd y Ddelw is a summit in the Carneddau mountains in north Wales, north-east of Foel-fras. It is the Nuttall top of Drum (Wales). Its eastern slopes are drained by the Afon Tafolog, a tributary of Afon Roe that flows through the village of Rowen before joining the River Conwy. It is also the final top on Carnedd Llewelyn's long northern spur. To the north-west is Tal y Fan, the most northerly 2000 foot tall mountain in the Carneddau and Wales. The summit has two large shelter cairns, hollowed out from a large Bronze Age burial cairn.
Afon Cych is a tributary of the River Teifi in south-west Wales. It is 13 km long, passes through a number of small settlements on the border between Pembrokeshire and Carmarthenshire, and is significant in Welsh legend.
The River Brenig is a tributary river of the River Teifi and runs through the market town of Tregaron in Ceredigion, Wales. It is formed from the confluence of the Afon Groes and Afon Berwyn in the foothills of the Cambrian Mountains.
The Afon Aber is a small river in Gwynedd that enters Liverpool Bay on the coast of North Wales at Abergwyngregyn, 53.242°N 4.027°W. It rises in the Carneddau mountains on the northern watersheds of Drum, Foel Fras and Garnedd Uchaf and the eastern watersheds of Drosgl and Moel Wnion. It is principally noted for the spectacular waterfall of one its principal tributaries, the Aber Falls, where it leaves the hills and descends in a single drop to the valley floor. The river, joined by the other main tributary, the Afon Anafon, then flows through a densely wooded valley which is now a nature reserve before entering the sea just north of Abergwyngregyn.
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.
The Afon Ffraw is a short river on the Isle of Anglesey, Wales. It arises at Llyn Coron and flows southwest for two miles along the northwestern margin of Twyn Aberffraw via the village of Aberffraw to Aberffraw Bay on the island's west coast. The river is tidal to a point just northeast of Aberffraw and is accompanied by the Wales Coast Path and Isle of Anglesey Coastal Path. Llyn Coron is fed by the Afon Gwna which rises near to Llangefni in the centre of Anglesey. The flow of the Ffraw is bolstered by the left-bank tributary, the Afon Frechwen and a larger, though unnamed right-bank tributary which rises near Gwalchmai. Pont Aberffraw is a bridge spanning the river constructed as a single stone arch in 1731. When the A4080 main coastal road was diverted onto a new line, the old bridge closed to traffic.
