Conwy RSPB reserve is a nature reserve of the Royal Society for the Protection of Birds situated on the east side of the Conwy estuary in Conwy county borough, North Wales. It covers 47 hectares (114 acres) and protects a variety of habitats including grassland, scrubland, reedbeds, salt marsh and mudflats. It was created as compensation for the destruction of areas of wildlife habitat during the construction of the A55 road tunnel under the estuary between 1986 and 1991. Waste from dredging was dumped onto the site which was later landscaped to create two large pools and several smaller ones. The reserve opened to the public on 14 April 1995 and facilities for visitors now include a visitor centre, café and three hides.
