Malahide Bay is a coastal bay north of Dublin Airport, forming the outer estuary of the Malahide River. The bay is a designated Special Protection Area for its birdlife. For paddlers, the primary access is from Malahide Beach, which provides a launch point into the bay. The area experiences significant tidal influence, and the entrance to the Malahide River is a historical wreck site, indicating potential navigational hazards. The bay is exposed to the Irish Sea, so wind and wave conditions can develop, particularly on the open water side. A railway line, the DART, crosses the bay on a viaduct, creating a notable landmark during a paddle. The water quality in the outer estuary has been assessed as potentially eutrophic, representing a decline in status, which may affect general water clarity and ecological balance. The surrounding area includes the village of Malahide, which likely offers amenities, and the vista from the water includes views of the coast and the airport flight path. The bay's historical significance includes its ancient name, Inber Domnann, and its mention in medieval apocalyptic literature as a prophesied invasion site.
