A layover in Iceland is one of the few stopovers actually worth planning around — Icelandair and Play both route huge numbers of transatlantic passengers through Keflavik (KEF), and the airport sits close enough to both Reykjavik and the Blue Lagoon to make a long layover genuinely worthwhile. How much you can see comes down almost entirely to how many hours you have.

How Much Time Do You Need?
| Layover Length | What’s Realistic |
|---|---|
| Under 5 hours | Stay at the airport — not enough time to leave and safely return |
| 5–6 hours | Keflavik town itself, or a quick taxi loop nearby |
| 6–8 hours | The Blue Lagoon (bare minimum for this) or the wider Reykjanes Peninsula |
| 8+ hours | Reykjavik itself, with time to spare |
Build in roughly 30 minutes for passport control, 25–45 minutes of travel time each way, and standard re-check-in buffers — Iceland’s changeable weather can also slow down transfers, so don’t cut it too close.
Visiting the Blue Lagoon on a Layover
The Blue Lagoon is about 20 minutes from Keflavik Airport, closer than Reykjavik itself, which is why it’s the go-to stop for a mid-length layover. Plan on roughly 2–2.5 hours at the lagoon plus transfer and re-entry time — six hours total is the realistic minimum, and book your entry slot in advance, since it frequently sells out, especially in summer.
Visiting Reykjavik on a Layover
Reykjavik is about an hour from the airport by Flybus or taxi. With 8–9 hours total, you can comfortably fit a return trip plus a few hours to explore the compact city center — Hallgrímskirkja church, the harbor, and the main shopping street Laugavegur are all within easy walking distance of each other.
