Birdwatchers should head 3km northwest of Eyrarbakki to Flói Nature Reserve, an important estuary and marshland on the eastern bank of the Ölfusá. It’s visited by many wetland birds – common species include red-throated divers and various kinds of ducks and geese – most present during nesting season (May to July). There’s a 2km circular hiking trail through the marshes. For more information, contact the Icelandic Society for the Protection of Birds .
