Iceland in Autumn: What Changes and What It Costs

When autumn actually starts — and where it hits first

Autumn in Iceland runs roughly from the first week of September to the end of October, with the shift most obvious in the Westfjords and the highlands. By mid-September, roads into Landmannalaugar and the F208 to Þórsmörk close for the season, and the ferry to Hornstrandir stops running. Along the south coast, Seljalandsfoss and Skógafoss stay open year-round, but the 2.5-hour drive from Reykjavík to Vík gets darker earlier — sunset drops from 20:30 on 1 September to 18:00 by 10 October.

The upside is space. In July, the Þingvellir car park fills by 10:00; in late September you can arrive at noon and still find a spot. The Golden Circle loop — Þingvellir, Geysir, Gullfoss — takes about 6 hours with stops, and the 300 km round trip from Reykjavík is comfortable in a day. If you want fewer coaches, go after 15 September, when many package tours stop.

What it costs: accommodation, car hire and fuel

Hotel prices fall noticeably after 15 September. A double room in central Reykjavík (101 or 105 postcodes) that costs 30,000–40,000 ISK in July drops to 20,000–28,000 ISK in October. Outside the capital, expect 18,000–25,000 ISK for a guesthouse room with shared bathroom in Vík or Höfn, and 25,000–35,000 ISK for a private cottage near Húsavík. Hostel dorms run 6,000–9,000 ISK. These are typical ranges — check the booking site for live rates, since aurora season pushes some dates up again in late October.

Car hire also gets cheaper: a compact 2WD that costs 12,000–15,000 ISK per day in August falls to 8,000–11,000 ISK in October. A 4WD for highland F-roads costs 20,000–25,000 ISK in summer and 15,000–18,000 ISK in autumn, though most F-roads are already closed. Fuel is around 300 ISK per litre for petrol; a Reykjavík–Vík–Höfn–Reykjavík loop of about 800 km will use roughly 60–70 litres, so budget 18,000–21,000 ISK.

Weather, roads and the northern lights

September is still mild: Reykjavík averages 8–10°C, with wind and rain. October drops to 3–6°C, and the first snow often dusts the roads over Hellisheiði (the pass on Route 1 between Reykjavík and Selfoss) by mid-month. Check road.is and vedur.is daily — closures on Route 1 near Vík or on the Eastfjords passes can add hours. Daylight shrinks fast: on 1 September you have about 13 hours of light; by 31 October, only 8. That means shorter driving days and more time in the evenings for aurora hunting.

The northern lights become visible again from late August, but the real season starts in mid-September when nights are dark enough. Head away from Reykjavík's light pollution: the Grótta lighthouse at Seltjarnarnes is 10 minutes from downtown, but for darker skies drive 45 minutes to Þingvellir or 1 hour to the Reykjanes Peninsula. A clear, moonless night between 22:00 and 01:00 gives the best odds. Book a hotel with a aurora wake-up call — many countryside guesthouses offer this.

What to book, what to skip, and where to stay

For a 5–7 day autumn trip, I'd book a night in Reykjavík (101 Hotel or Kex Hostel for budget), then two nights around Vík (Hotel Kría or a guesthouse like Puffin Hotel Vík), and one or two nights near Höfn or the Jökulsárlón lagoon. Skip the highlands and the Westfjords unless you have a 4WD and flexibility — roads close without warning. Also skip the Blue Lagoon at peak times (11:00–14:00); go after 16:00 when it's quieter and cheaper. The Sky Lagoon in Kópavogur is a good alternative and closer to the city.

If you're basing yourself in Reykjavík, stay in 101 or 105 for walkability to Hallgrímskirkja, Harpa and the harbour. For aurora, book a countryside hotel like Hotel Rangá (2 hours from Reykjavík) or Fosshotel Glacier Lagoon (5 hours). My pick: three nights in Reykjavík at a mid-range hotel (20,000–25,000 ISK per night), then two nights near Vík to combine south-coast sights with dark skies. Book by early September — autumn weekends fill up fast, especially around the first week of October. Details were verified in September 2026.
