Grótta Lighthouse

Reykjavik's Edge of the World

Grótta sits at the westernmost point of the Seltjarnarnes peninsula, the very tip of the Reykjavik capital area. Beyond the small white lighthouse, there is nothing but the North Atlantic stretching toward Greenland. On a clear evening, the sun sets directly behind Snaefellsjokull glacier across the bay, painting the sky orange and pink. It is the most accessible place in the Reykjavik area to feel like you have left the city behind.

The lighthouse stands on a small tidal island — a flat rocky outcrop that connects to the mainland by a narrow causeway. At low tide, you can walk across and explore the island. At high tide, the sea covers the path and the lighthouse becomes an island in the truest sense. This rhythm of access and isolation is part of what makes Grótta special.

Visiting the Lighthouse

The lighthouse itself is not open to visitors, but the island around it is worth exploring at low tide. The rocky shore is strewn with seaweed and shells, and the views are panoramic — Mount Esja to the north, Snaefellsjokull to the west, and the Reykjavik skyline to the east. On a calm day, the reflections in the tidal pools are beautiful.

Check tide tables before visiting. The causeway can flood quickly as the tide comes in, and being stranded on the island until the next low tide is a real possibility. Local tide information is available online and posted at the parking area.

Birdwatching

Grótta is designated as a nature reserve and is one of the most important bird nesting sites in the Reykjavik area. Arctic terns, eider ducks, and various wading birds nest in the area during spring and summer. The entire island and shoreline are closed to visitors from May 1 to July 15 to protect the nesting birds.

Outside nesting season, the area attracts wintering birds and is a pleasant spot for birdwatchers. The flat terrain and open views make it easy to spot species along the shore.

Northern Lights and Sunsets

Grótta's western exposure and distance from the worst of Reykjavik's light pollution make it the go-to spot for Northern Lights viewing within the capital area. On clear autumn and winter nights, the aurora dances above the lighthouse and the bay. The lighthouse provides excellent foreground for long-exposure photographs.

Sunset watching is equally rewarding. From late spring to midsummer, the sun barely dips below the horizon, creating extended golden-hour conditions that photographers treasure.

The Hot Foot Bath

Near the parking area, a small geothermal foot bath offers a simple pleasure — warm water for tired feet. The concrete basin is filled with naturally heated water from a geothermal source beneath the beach. It is free, open year-round, and surprisingly satisfying after walking along the cold, windswept shore.

Getting There

From central Reykjavik, drive or cycle west through Seltjarnarnes to the end of the road. The drive takes about 15 minutes. Free parking is available near the shore. Bus route 11 runs from the city centre to Seltjarnarnes, from where it is a short walk to the lighthouse area.
