Ynys Moelfre is a small island off the coast of Anglesey, Wales.[1] At low tide it has a maximum length of 261 metres and a maximum width of 121 metres with a maximum area of 6.6 acres (27,000 m2). The nearest settlement to the island is the village of Moelfre, and the two are separated by a shallow channel called Y Swnt (The Strait or The Sound), which is never more than 194 metres wide and can at low tide only be waist-deep all the way across. At extreme low Spring tides, it is possible to walk across to the island on dry ground all the way. Due to its proximity to the mainland there are grasses found on the island and a few wild flowers. Species of birds that can be found on the island include gulls, terns, gannets, fulmars, and Great/Arctic skuas. Porpoises are occasionally seen also. There are, however, no man-made structures. It is referred to by some locals as Rat Island.
