The Menai Strait is a strait which separates the island of Anglesey from Gwynedd, on the mainland of Wales. It is situated between Caernarfon Bay in the south-west and Conwy Bay in the north-east, which are both inlets of the Irish Sea. The strait is about 25 km (16 mi) long and varies in width from 400 metres (1,300 ft) between Fort Belan and Abermenai Point to 7.5 kilometres (4.7 mi) between Puffin Island and Penmaenmawr. It contains several islands, including Church Island, on which is located St Tysilio's Church.
Menai Bridge is a town and community on the Isle of Anglesey in north-west Wales. It overlooks the Menai Strait and lies by the Menai Suspension Bridge, built in 1826 by Thomas Telford, just over the water from Bangor. It has a population of 3,376.
The Menai Suspension Bridge is a suspension bridge spanning the Menai Strait between the island of Anglesey and the mainland of Wales. Designed by Thomas Telford and completed in 1826, it was the world's first major suspension bridge. The bridge still carries road traffic and is a Grade I listed structure.

A fishing weir, fish weir, fishgarth or kiddle is an obstruction placed in tidal waters, or wholly or partially across a river, to direct the passage of, or trap fish. A weir may be used to trap marine fish in the intertidal zone as the tide recedes, fish such as salmon as they attempt to swim upstream to breed in a river, or eels as they migrate downstream. Alternatively, fish weirs can be used to channel fish to a particular location, such as to a fish ladder. Weirs were traditionally built from wood or stones. The use of fishing weirs as fish traps probably dates back prior to the emergence of modern humans, and have since been used by many societies around the world.

It carries both the North Wales Coast Line for trains, which runs from Crewe to Holyhead and the A5 road between London and Holyhead. The embankment was designed by, and its construction overseen by, Thomas Telford and was named after the Stanley family who were significant benefactors to the area.
The Menai Strait fish weirs are historically important fishing traps used in the fast-flowing tidal waters of the Menai Strait, which separates Anglesey from the rest of North Wales. The strait was particularly well suited to utilising fish weirs. The tidal waters pull huge volumes of water past the coastline with every tide, and the weirs and traps enabled fish to be concentrated into small holding areas from which they can be readily caught. Such methods are thought to have been used from earliest times, but the submerged and standing remains along both the Anglesey and Gwynedd coasts are from medieval and post-medieval periods, and in some cases were still in use into the 20th century.
Llanddona fish weir is a post-medieval fish trap sited in Llanddona, on the Isle of Anglesey. The fish weir is a scheduled monument.

There is a two-storey house on the island with three outbuildings and a boathouse.
Lavan Sands is an intertidal sandbank found in the Menai Strait between Bangor, Gwynedd and Llanfairfechan, Wales. Totally underwater at high tide, at extreme low tides it measures 5.5-mile (8.9 km) east-west and 3.25-mile (5.23 km) north-south. At the western end is found another sandbank Bangor Flats and just north is the sandbank Dutchman's Bank. At low tide the Lavan Sands make the narrowest part of the Menai Strait, at Beaumaris, a mere 237 m (778 ft). The area is designated as an SSSI due in part to the large numbers of Eurasian oystercatchers that migrate there due to the freshwater streams that flow across it.
