Can I leave the airport on a layover in Reykjavik?

Here is where the six hours go. Passport control at Keflavík tends to take 15-30 minutes when the morning wave of transatlantic flights lands between 06:00 and 07:30, and longer when two US arrivals land together. The Flybus to BSÍ currently costs about ISK 4,000 one way, around $33 at 121 ISK to the dollar, with departures timed to arrivals. Strætó route 55 is cheaper, but it runs far less often and stops early in the evening. A taxi runs ISK 20,000 or more, and on your own nobody splits it. Catch the return Flybus at least 2.5 hours before departure, because the ride back plus the non-Schengen passport desk on the way out can take over an hour. That leaves roughly two hours in Reykjavik. If your ticket is with Icelandair, its Stopover programme lets you break a transatlantic trip in Iceland for up to seven days at no extra airfare, which is often the better plan.

Two hours in Reykjavik covers the walk up Skólavörðustígur to Hallgrímskirkja, where the tower lift costs around ISK 1,400 and looks out over the red and teal roofs of Þingholt. Sundhöllin, the 1937 public pool on Barónsstígur, is five minutes downhill, and its rooftop hot tubs are where Reykjavik residents grumble about the weather and the government, steam rising off the water into cold air. We rate it the best social hour in the city for anyone travelling alone, at about ISK 1,300. One rule at Sundhöllin is strict: Icelandic pool attendants expect you to shower naked before you swim, and they will send you back if you skip it. Finish at Bæjarins Beztu Pylsur near the Old Harbour, where a hot dog with crunchy fried onions and sweet brown remoulade costs about ISK 800 and a table for one draws no looks.

For a shorter connection, the Blue Lagoon in the Reykjanes lava field is the more practical stop, with coaches running directly from the terminal. Book a timed entry online before you fly: walk-ups get turned away on busy mornings, and the cheapest Comfort tickets have recently cost more than ISK 10,000. The milky water smells faintly of sulphur and the silica mud feels gritty on your face. Our honest view is that it is expensive and crowded, and yet one ticket costs the same whether you go alone or as a couple, which is rare in Iceland. Eruptions on the Sundhnúkur crater row near Grindavík closed the lagoon several times between November 2023 and 2025, so check its status on the morning you land. The entrance building stores carry-on bags for a small fee.

Reykjavik scores 9.3/10 for solo-traveler safety (see the TTDI Solo-Safety Index), and in our experience the real layover risks here are weather and timing, not crime. On 19 October 2026 the city was at 7.5°C under overcast skies, and the wind brought the feels-like temperature down to 1.3°C. In late October the sun rises around 08:50 and sets around 17:35, so after an early arrival you will walk Laugavegur in the dark. It is safe, but wet pavements and wind-driven drizzle make it slow going, so keep a windproof shell and a hat in your carry-on. Austurstræti gets loud and drunk after 01:00 on Friday and Saturday nights, and that is the one time we would keep a phone in an inside pocket. Almost every Icelandic business takes cards, so you do not need cash krónur.
