The Breidafjordur is a vast shallow bay on the west coast of Iceland between the wilderness of the North-West Peninsula to the north and the Snaefellsnes to the south. The bay has numerous islands with grassland and marshes and extensive intertidal areas along its deeply indented coastline. Snaefellsnes is a long and narrow peninsula with rocky sandstone cliffs holding important seabird colonies on the southern side and rocky shores and sandy lagoons on the coast of the bat to the north. The Breidafjordur is famous as the last resort of most of Iceland's remaining White-tailed Eagles and the islands of the bay support a few pairs of Grey Phalarope, a very rare breeding bird in the Western Palearctic. Harlequin Duck, an Icelandic speciality, can be seen both within the bay and on the southern side of the Snaefellsnes. Gyrfalcon breeds on the peninsula and the seabird colonies include Shag and Cormorant, Black, Common and Brunnich's Guillemot, Razorbill and Puffin, Glaucous Gull and Fulmar. Divers, Whooper Swan, Greylag Goose, Scaup, Long-tailed Duck and Eider also breed as well as Arctic Skua and Arctic Tern, Ptarmigan and Snow Bunting. Red-necked Phalarope, Purple Sandpiper, Whimbrel and Golden Plover are among the waders present in summer. Brent Goose occurs on passage and huge numbers of Knot and other waders visit the intertidal areas on migration. Iceland Gull is present in winter. Common and Grey Seals are commonly seen and in recent years the area has become an important base for whale-watching trips. These can be arranged at either Stykkisholmur or Olafsvik on the northern coast of the peninsula and cetaceans to be seen include White-beaked Dolphin, Killer and Pilot Whales with the possibility of Sperm and Humpback, Fin, Sei, Minke and even Blue Whales on the longer trips. There are roads around the perimeter and across the centre of the peninsula and also along the shore of the Breidafjordur enabling the entire area to be easily explored and there is regular public transport from Reykjavik. Accommodation is available in Stykkisholmur, Borganes and elsewhere and camping is possible at Olafsvik. There are regular boats across the bay from Stykkisholmur to Brjanslaekur on the North-West Peninsula which stop at some of the many islands including Flatey which has breeding Grey Phalarope and Black Guillemot.
