Afon Menai is a picturesque sea inlet located in the county of Anglesey, Wales. It separates the island of Anglesey from the mainland of Wales and is an important waterway connecting the Irish Sea to the larger Menai Strait. The name "Afon Menai" translates to "River Menai" in English.

This estuary stretches approximately 25 kilometers in length, with its mouth opening into the Irish Sea near the town of Beaumaris. The waterway is characterized by its strong tidal currents, which can reach speeds of up to 8 knots during peak times. These currents make Afon Menai a popular destination for watersport enthusiasts, such as sailors, kayakers, and windsurfers, who enjoy challenging themselves in its dynamic environment.

The estuary is also home to a diverse range of wildlife. Its shores are lined with saltmarshes, mudflats, and sandbanks that provide important habitats for various bird species, including oystercatchers, curlews, and herons. Seal sightings are not uncommon in the area, as they are known to frequent the estuary's waters.

Afon Menai has played a significant role in the history of the region. It has served as a strategic waterway for trade and transportation, allowing ships to access the important port of Caernarfon. The iconic Menai Suspension Bridge, built in 1826 by Thomas Telford, spans the estuary, connecting the Isle of Anglesey to the mainland. This architectural marvel is a popular tourist attraction, offering stunning views of the surrounding area.

Overall, Afon Menai is a beautiful and dynamic waterway that combines natural beauty, recreational opportunities, and historical significance, making it a significant part of the Welsh landscape.
