Grótta lighthouse and coast
Find open sea, birdlife and a lighthouse at the edge of Seltjarnarnes, with a mainland walk that works without crossing to the island.
Plan a real visit
Your visit at a glance
- Time on site
- 45–90 min on site · editorial estimate; travel extra
- Start
- The western end of Seltjarnarnes at Grótta’s mainland approach; follow the signed coastal paths.
- Island closure
- The island is closed to visitors from 1 May through 31 July for nesting birds. Follow the marked closure boundary; mainland viewpoints avoid the island crossing.
- Tides
- The connecting spit floods at high tide. Use the local tide table and allow a return margin; mainland views avoid the crossing.
- Choose the visit
- Daylight coast and birdwatching; after dark, aurora viewing only when darkness and sky conditions suit.
The city feels farther away at Grótta. The lighthouse, low shore and open horizon make a simple coastal outing, especially when you want space after the busy centre.
You do not need to reach the lighthouse island to enjoy the view. The mainland coast is the sensible starting point, and the island has both a tide constraint and a seasonal nesting closure.
- A useful time allowance
- 45–90 minutes at the coast, plus travel — our allowance
- Season and conditions
- Year-round, subject to current access and conditions
- Getting there
- The municipality lists Strætó route 11 to Lindarbraut/Hofgarðar, followed by about 15 minutes on foot to Grótta. Check the Strætó planner for the service and return journey on your visit date.

Plan your next step
Start with the option that matches how you will visit Grótta lighthouse and coast. The alternative is useful only if it fills another gap in your plan.
These parts of your trip are already arranged. Keep the guide handy and check conditions before you go.
A mainland-first walk
Begin with the lighthouse view from the mainland and choose a short out-and-back on the signed shore path. Our 45–90-minute visit allows for watching the water and birds, without assuming access to the island.
Outside the nesting closure, crossing still depends on the tide. The municipality links its tide table; being able to walk out does not establish that the return will stay dry. Skip the crossing if you cannot judge the safe return window.
Grótta by bus: include the walk and the return
The municipality lists route 11, Lindarbraut/Hofgarðar, then about 15 minutes on foot to Grótta. Check the Strætó planner for your date and both directions before leaving the centre; this is an arrival guide, not a promise of a particular departure.
For a 60-minute mainland coastal visit, our sample budget is 15 minutes walking out + 60 minutes at the coast + 15 minutes back = 90 minutes between arriving at the stop and being ready for the return bus. Add bus travel, waiting and a margin for weather or a slower group.
Choose the return connection first if visiting after dark. The island is closed 1 May–31 July; outside that period, use the official tide table for your visit date. A low-tide arrival does not guarantee a safe return. The mainland viewpoint is a complete visit when the crossing or wind is unsuitable.
A possible evening, not a promise
Grótta can be an aurora-viewing location, but darkness, cloud cover and activity determine whether there is anything to see. A clear horizon is useful; no location guarantees a display.
Compare an independent mainland outing with the organised options in our northern-lights guide. Transport home and warm clothing matter more than reaching the island in the dark.
