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.

Caernarfon Airworld Aviation Museum is an air museum located on the former Royal Air Force station at Llandwrog, near Caernarfon in North Wales.

Groeslon railway station served the village of Groeslon, Gwynedd, Wales. It operated first as part of the Nantlle Tramway and afterwards as a railway under the auspices of several different companies. The station and line closed on 7 December 1964 as recommended in the Beeching Report.

Groeslon (Welsh pronunciation; Welsh: Y Groeslon, "the crossroads") is a small village in the community of Llandwrog in the Welsh traditional county of Caernarfonshire. Groeslon is administered by Gwynedd Council. The population was 880 at the 2011 censusNearby villages are Penygroes, Carmel and Dinas. The village lies approximately five miles south of Caernarfon. It has one primary school in the centre of the village and no secondary schools. Most secondary school age pupils go to Ysgol Dyffryn Nantlle in Penygroes. Groeslon was by-passed in 2002 by the A487 road, a trunk road which cost around £12 million to complete. A bat bridge was constructed in 2010 to guide lesser horseshoe bats across the road. Formerly an agricultural and slate mining village, Groeslon is now expanding as a commuter village for the surrounding towns, especially Caernarfon and Bangor. Its initial growth came as a result of the construction of the LMS railway in 1867. Groeslon railway station closed in December 1964. The railway line is now part of the national cycle route. In the village there is one pub called the Penionyn. At the bottom of the village, bordering the A487, a huge wall becomes visible. This is the wall to the Glynllifon estate, formerly the seat of Lord Newborough, which is now a country park and college (Meirion Dwyfor) specialising in land based industries, e.g. agriculture, equine studies and arboriculture. Groeslon is covered by a Neighbourhood Policing Team based in Penygroes.

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.

Llanwnda railway station served the village of Llanwnda, Gwynedd, Wales.

Royal Air Force Llandwrog or, more simply, RAF Llandwrog is a former Royal Air Force station located at Llandwrog, southwest of Caernarfon, Gwynedd, Wales. The site opened in January 1941 as a RAF Bomber Command airfield for training gunners, radio operators and navigators and closed after the end of the Second World War in 1945. It reopened in 1969 and remains in civil operation today as Caernarfon Airport.

Penygroes railway station was located in Penygroes, Gwynedd, Wales.The narrow gauge, horse-drawn Nantlle Railway had a station near the site from 1856. From the outset timetables appeared regularly in the "Carnarvon & Denbigh Herald" and in Bradshaw from October 1856. In 1865 the narrow gauge line was closed, to be replaced and updated to standard gauge with contemporary facilities. It reopened in its eventual form in 1867 and closed in December 1964. The station served as the junction station for the short branch to Nantlle which was overlain in 1872 on part of the former Nantlle Railway route, but its main purpose was for traffic on the former Carnarvonshire Railway line from Caernarvon to Afon Wen and beyond.When the line and station were first opened in 1867 a locomotive was hired from the Cambrian Railways. A Cambrian driver, who had never been over the line before, was retained to drive the first directors' inspection special from Afon Wen to Carnarvon (Pant). On the return journey the loco ran short of coal and ran out of steam at Penygroes. There was some peat in a nearby field, which the crew dug and the directors carried to the engine enabling steam to be raised.The passenger service along the Nantlle Branch was withdrawn in 1932, though excursions continued until 1939. The station and line closed on 7 December 1964 as recommended in the Beeching Report. The station building and footbridge remained in place, but increasingly derelict, until at least 1970.

The Afon Llyfni is a small river in North Wales which arises as Nant Drws y Coed between Mynydd Mawr and Mynydd Drws-y-Coed just to the west of Snowdon. The main river forms at the outlet of the Llyn Nantlle Uchaf and flows past the great slate workings of Nantlle picking up drainage from the very deep flooded quarries. It then passes to the south of Talysarn and Penygroes before eventually discharging to the sea at Pontllyfni. For a number of years there were concerns that the quality of the river might be polluted because of illegal and historical dumping of industrial waste in one of the deep, water-filled quarries. However, it appears that there has been little or no detectable quality shift.
