Grótta Lighthouse

Gróttuver

Reykjavik Area

Grótta sits at the tip of the Seltjarnarnes peninsula, less than 20 minutes from central Reykjavík, and it's probably the easiest place in the capital region to feel away from the city. The lighthouse — first built in 1897, rebuilt in 1947 — stands on a small tidal islet accessible across a sandy causeway at low tide. The crossing window is only a few hours, so check tide tables before going. From September through April, dark skies and unobstructed ocean views make Grótta one of the better aurora spots reachable from Reykjavík. The area also holds Kvika, a small geothermally heated seawater foot pool on the coast at around 39°C — warming your feet while watching for lights is a legitimate use of a winter evening. Parking is free and the site is open at any hour. Between May 1 and July 15, the islet itself is closed during the bird nesting season — Arctic terns, eiders, and other seabirds breed here. You can still walk the coastal path on the peninsula during this period. The rest of the year it is a calm, uncrowded spot that most visitors to Reykjavík never find.
