Y Foryd (meaning 'the estuary' or 'the inlet'), also known as Foryd Bay, is a tidal bay in Gwynedd, Wales. It is located at the south-western end of the Menai Strait, about two miles south-west of Caernarfon. Several rivers flow into the bay and there are large areas of mudflats and salt marsh. A shingle spit partly blocks the mouth of the bay. At the north-western end is Fort Belan, built during the 18th century. Aerial photography in the drought of 2018 identified rectangular structures possibly of Roman age, at Glan y Mor, on slightly raised ground adjacent to the shoreline. This layout is very unusual in Roman Wales; it is rectilinear but has no defences and is otherwise unlike the military Roman sites in Wales, nor does it resemble the native defended settlements with their roundhouses and irregular outlines, nor the occasional villas. It is similar to the buildings and ditched enclosures excavated on the other side of the Menai Strait at Tai Cochion. To the south is a rectangular ditched structure or possible building, with an internal subdivision, measuring 25 by 13 m. To the north is a pair of almost identical structures; both groups are linked by a linear ditch or boundary. Close by, an early field system runs north-west to south-east between Plas Farm and the shores of the Menai Strait; the fields are rectangular, with at least one visible ditched hollow way.The bay has been designated a Site of Special Scientific Interest and in 1994 it became a Local Nature Reserve because of its importance for wildlife. Many birds visit in winter and during migration, including large numbers of wildfowl and waders such as wigeon which peak at over 3000 birds. Notable species include brent goose, jack snipe, spotted redshank and greenshank. Terns roost at the mouth of the bay.

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 (Y Foryd). 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 name may signify the '(river of) curved places', referencing its meandering course.

Abermenai Point (Welsh: Pwynt Abermenai) is a headland in the southeast of the island of Anglesey in Wales. It is the southernmost point of the island and is the northern point of the western entrance of the Menai Strait. The headland is mainly composed of sand dunes at the end of Newborough Warren and has no road leading up to or onto it. The nearest major public road, along which a public bus runs is the A4080 at Newborough. Due to its exposed location and the nature of the straits the Ordnance Survey map for the point carries a warning "Public Rights of Way to Abermenai Point can be dangerous under tidal conditions." The earliest recorded ferry crossing route from the island to the mainland ran from the point to the site at which Fort Belan now sits. Records in the late 11th century relating to the then King of Gwynedd, Gruffudd ap Cynan state that a ferryman was employed there and ferry houses at both locations have been recorded throughout history. In 1725, Daniel Defoe, the author of novels such as "Robinson Crusoe" used the crossing on his way to Holyhead. The ferry ceased to run in the mid-19th century and by the 1940s almost all trace of it had disappeared. The decline of the ferry service was almost certainly due to the construction between 1846 and 1850 of the Britannia Bridge further up the strait which brought the railway to the island.

Llanfaglan is a parish in Gwynedd, north-west Wales. It lay in the medieval cwmwd of Is Gwyrfai. Llanfaglan is a medieval parish bordering with the parish of Llanbeblig, Caernarfon, on the shore of the Menai Strait and Traeth y Foryd. It is in the modern community of Bontnewydd. The church in Llanfaglan, St Baglan's (Grid reference SH 455 606) stands alone in the middle of a field and is now owned by the Friends of Friendless Churches. In 2005, it was discovered that the church and the older part of the cemetery were part of a pentagonal enclosure. The period of this enclosure is not known as it is the only one of this type known of in Europe up to now. A 5th or 6th Century gravestone inscribed with Fili Lovernii Anatemori, has been reused as a lintel over the door. This was the gravestone of Anatemarios, mab Loverniws. Although the Christian church probably dates from the 13th century, additions date from the 17th century as do the internal fittings. The church remains consecrated and is still in occasional use.

Fort Belan (alternative: Belan Fort; pronounced: Bell-ann) is a coastal fortress in North Wales. It is located opposite Abermenai Point, at the south-western end of the Menai Strait, on the coast of Gwynedd, in the parish of Llanwnda. Situated at the tip of the Dinlle Peninsula, the windblown, north-westernmost point of the Welsh mainland, the fort is cut off twice a day by the incoming tide.
