Iceland
A wind-battered island where you step across the Arctic Circle among a million nesting seabirds.
The concrete sphere marks the line — the Arctic Circle, 66°33' north — and beyond it there is nothing but nesting seabirds, wind, and the knowledge that you have run out of Iceland. Grímsey lies forty kilometres off the north coast, the only piece of Iceland above the Circle.
Grímsey holds around sixty permanent residents and seabirds in their hundreds of thousands, including one of Iceland's densest puffin colonies on its eastern cliffs. Its defining oddity is the Circle itself: the line drifts north a little every year, so the island's marker — Orbis et Globus, a three-tonne concrete sphere — is rolled to follow it. In high summer the midnight sun still rides clear of the horizon here after it has dipped on the mainland. The Sæfari ferry sails from Dalvík in about three hours, flights from Akureyri take twenty-five minutes, and the whole five-square-kilometre island — church, lighthouse, guesthouse, harbour — walks comfortably in an afternoon.
Solo
Stepping over the Arctic Circle on a tiny island in the open sea, seabirds overhead and nothing else — a geographic solitude nowhere else in Iceland can stage.
Couple
Crossing the line together, watching true midnight sun from Iceland's northern extremity and sharing a guesthouse on a sixty-person island makes a milestone of the trip.
Friends
The ferry out, the Circle crossing and the puffin cliffs give a group bragging rights and wildlife in one day from Akureyri.
