Grindøysundet naturreservat

Grindøysundet naturreservat stretches across a coastal landscape in Norway, with low islands, tidal flats and shallow, shimmering water. The reserve covers roughly 7,987 decares, most of it sea, while Grindøya carries old hayfields, marshes and rocky heath. Saline meadows and reed beds meet low ridges, creating varied habitats within a compact island setting.

Eider ducks, long-tailed ducks and black guillemots use the surrounding waters. Shorebirds and gulls nest along beaches and tidal flats, while raptors and terns sometimes pass through. Protection began in 1995 to preserve feeding grounds, nesting areas and botanically rich sites. Scientific monitoring of eiders has continued since 1984, forming one of Norway’s longest studies of sea ducks.

Three seasonal cabins mark the limited human presence among occasional boat and kayak visitors. Motorised travel on land and camping are forbidden, while much of the island closes during the spring breeding season. Watch the tidal edge for an oystercatcher probing the mud, or a flock lifting suddenly from the water.
