Herdla

Herdla is a small island and surrounding islets off the coast of Vestland county in western Norway, within Askøy municipality. It is notable for its seabird populations and visible Second World War fortifications.

The island group provides shoreline and marsh habitats that attract migratory seabirds and waders, with boardwalks and vantage points for birdwatching and nature photography. Remains of wartime concrete gun emplacements and bunkers are accessible on walking routes and are a frequent point of interest.

Herdla was militarised during the Second World War when occupying forces built coastal defences and related infrastructure on the island; these concrete structures remain as ruins. The island has long been used for fishing and grazing, and more recently for nature conservation and recreation.

Herdla sits off the coast of Askøy in Vestland, on Norway’s western seaboard, within the archipelago near the mouth of nearby fjords. It is reached from the mainland by road and short boat links from the surrounding shoreline.

• Birdwatching season: Best visited during spring and autumn migration when numbers of seabirds and waders concentrate along the shores, and bring binoculars for close-up viewing.
• Access and facilities: Simple waymarked paths and a small visitor facility make the island suitable for day visits, but check local boat or ferry schedules if not walking from the mainland.
