Iceland is experiencing its busiest road traffic weekend of 2025, with congestion peaking on routes in and out of Reykjavík, around Akranes, and along the most-travelled stretches of the Ring Road. Icelandic road and transport authorities have flagged this weekend as a high-alert period for delays, urging drivers to plan ahead before they set out.
Key takeaways
- This weekend marks the single busiest traffic period on Iceland’s roads in 2025.
- Routes near Akranes and Reykjavík — including the Hvalfjörður tunnel approach — are seeing the heaviest congestion.
- Travelling before 8 a.m. or after 8 p.m. significantly reduces the chance of delays.
- Road conditions and live traffic updates are available at road.is, run by the Icelandic Road and Coastal Administration (Vegagerðin).
- Tourists and residents heading to popular destinations should expect longer journey times and consider alternative routes.
Which roads in Iceland are most congested this weekend?
The heaviest congestion is centred on western Iceland, particularly the approaches to Akranes and the western entrance to Reykjavík. The road corridor running from the capital out past Hafnarfjörður and along Route 1 — the Ring Road — toward the south coast is also under significant pressure, as tourists head toward Selfoss and the Golden Circle.
Reports indicate that the Hvalfjörður tunnel (Hvalfjarðargöng), the toll tunnel linking Reykjavík to Akranes, is among the flashpoints. The tunnel, which cuts roughly 60 kilometres off the old coastal route around the fjord, typically moves traffic efficiently — but during peak holiday weekends, queues build at both portals. Drivers heading to Snæfellsnes and the Westfjords are routing through the same bottleneck, compounding the pressure.
The Golden Circle route — which takes visitors past Þingvellir National Park, Geysir, and Gullfoss — is also heavily loaded this weekend. The section of Route 36 from Mosfellsbær toward Þingvellir is particularly slow in the mid-morning hours when tour buses and private vehicles converge simultaneously.
In the capital itself, the roads in and out of Reykjavík’s western suburbs and the highway junction near Kópavogur are reporting slower-than-normal flow, especially on Saturday and Sunday afternoons when day-trippers return to the city.
When is the busiest travel weekend in Iceland in 2025?
Multiple Icelandic traffic and travel sources have identified this current weekend — in early-to-mid July 2025 — as the peak congestion point of the year. Iceland’s summer travel season runs broadly from June through August, but the specific combination of school holidays being fully under way, long daylight hours (Iceland experiences near-continuous daylight in July), and a high volume of international tourists arriving at Keflavík Airport creates a brief window when roads are under maximum strain.
Historically, the weekends immediately surrounding the Icelandic national holiday on 17 June and the height of July have produced the worst congestion. This year, officials say demand has remained consistently high throughout July, with rental car return traffic and new arrivals overlapping on the same routes at the same time.
Are there road closures or delays near Akranes or Reykjavík?
No major scheduled road closures have been confirmed for the Reykjavík metropolitan area this weekend, but unplanned delays are a near-certainty given current volumes. Akranes — a town of roughly 7,500 people on the Akranes peninsula, about 45 kilometres northwest of Reykjavík — is a popular day-trip destination, and all access routes into the town are experiencing slower travel times.
Construction works ongoing on stretches of the greater Reykjavík road network have reduced lane capacity at certain points and are contributing to queue formation even outside peak hours. Drivers should check road.is before departure for the latest status on any active works or closures. The site publishes real-time information in both Icelandic and English.
Anyone driving toward the Reykjanes Peninsula — where Keflavík International Airport sits, roughly 50 kilometres southwest of Reykjavík on Route 41 — should allow extra time, particularly during late morning and late afternoon slots when airport transfer traffic is highest.
How can tourists avoid traffic jams in Iceland this summer?
The single most effective step is adjusting departure times. Iceland’s long summer daylight means there is no logistical reason to drive at peak hours. Leaving before 8 a.m. or waiting until after 8 p.m. puts drivers ahead of or behind the main flow on almost every major route.
Beyond timing, the following practical measures make a significant difference:
- Use road.is for live updates. The Vegagerðin (Icelandic Road and Coastal Administration) updates conditions in real time and flags incidents within minutes.
- Consider the Hvalfjörður coastal route. While longer than the tunnel, the old road around the fjord is scenic and often completely free of congestion — it adds roughly 30–40 minutes but removes the tunnel queue entirely.
- Break up Golden Circle visits. Arriving at Þingvellir before 9 a.m. or after 6 p.m. dramatically reduces parking pressure and road congestion on Route 36.
- Avoid the Ring Road south on Friday evenings. The outbound flow from Reykjavík toward the south coast peaks between 3 p.m. and 7 p.m. on Fridays throughout July.
- Use safetravel.is for broader conditions. The Icelandic Association for Search and Rescue (ICE-SAR) and emergency services publish safety advisories at safetravel.is, covering weather, road conditions, and highland access.
Tourists hiring rental cars should also confirm whether their rental agreement covers the F-roads (highland interior tracks), which are strictly four-wheel-drive only and legally off-limits to standard vehicles. Taking an F-road shortcut in a two-wheel-drive car is both illegal and genuinely dangerous — and no shortcut at all if the vehicle becomes stuck.
What time of day is best to drive in Iceland during peak season?
Early morning is consistently the best window. Roads between Reykjavík and the major tourist corridors are quietest between 6 a.m. and 8 a.m. Traffic builds sharply from around 9 a.m. as day-trippers depart and tour buses begin their routes.
The second-best window is the late evening — from around 8 p.m. to midnight. Because Iceland has nearly 24-hour daylight in July, driving at 10 p.m. is visually and practically no different from driving at midday, but traffic volumes drop substantially. Many experienced Iceland travellers deliberately schedule their longest drives for the evening hours precisely for this reason.
The worst periods are Saturday and Sunday mid-mornings (9 a.m. to noon) and Friday late afternoons. If a journey can be moved by even two hours in either direction, the difference in travel time can be significant — particularly on single-lane sections of the Ring Road in the east and on the approaches to ferry terminals.
Drivers should also monitor the weather forecast from Veðurstofa Íslands (the Icelandic Meteorological Office) at vedur.is, since wind and rain can reduce safe driving speeds on exposed coastal and highland roads even in summer, adding further time to journeys already slowed by congestion.
Why this weekend is different
Iceland’s tourism numbers have returned to and in some measures exceeded pre-pandemic levels. The country received over two million visitors annually before 2020, and 2025 figures are tracking comparably. With a resident population of around 380,000, the ratio of visitors to locals during peak summer weekends places extraordinary pressure on infrastructure designed for a much smaller user base.
The road network outside Reykjavík remains largely single-carriageway — one lane in each direction — which means a single incident or slow-moving vehicle can create a queue stretching several kilometres with no overtaking opportunity. Road widening and bypass projects are ongoing but will not be complete this season.
Residents, particularly those in the greater Reykjavík area making routine journeys, are advised by local authorities to postpone non-essential trips this weekend where possible, or to use departure times outside the peak windows identified above.
Frequently asked questions
Is the Hvalfjörður tunnel the only route to Akranes?
No. The older coastal road around Hvalfjörður fjord remains open and offers a scenic alternative. It adds approximately 30 to 40 minutes to the journey compared to the tunnel route but avoids the toll fee (currently around 1,500 ISK for a standard passenger vehicle) and any queue at the tunnel portal. During peak weekends, the coastal route can actually be faster door-to-door.
Do I need a four-wheel-drive vehicle to drive in Iceland in July?
For the main paved roads — including the Ring Road, the Golden Circle, and routes to Akranes, the South Coast, and the Snæfellsnes Peninsula — a standard two-wheel-drive vehicle is sufficient in July. However, any road marked with an F prefix (F-roads into the highland interior) legally requires a four-wheel-drive vehicle. Driving a standard car on an F-road is illegal and voids most rental insurance policies.
Where can I check live road conditions in Iceland?
The authoritative source is road.is, operated by Vegagerðin, the Icelandic Road and Coastal Administration. The site provides real-time road status, construction updates, and closures in English and Icelandic. For weather-related hazards, check vedur.is (Veðurstofa Íslands). For general travel safety advisories, safetravel.is is the recommended resource.
How long does it take to drive the Golden Circle from Reykjavík on a busy weekend?
The Golden Circle loop — covering Þingvellir, Geysir, Gullfoss, and back to Reykjavík — is roughly 230 to 300 kilometres depending on the exact route taken, and normally takes around five to six hours including stops. On peak summer weekends, allow an additional 60 to 90 minutes for parking delays and slower road speeds. Departing before 8 a.m. is the most effective way to keep the journey close to the standard duration.
Is it safe to drive in Iceland at night during summer?
In July, Iceland does not get dark — the sun dips briefly toward the horizon around midnight but does not set, so visibility is not an issue. Fatigue can be, however, since the constant light disrupts sleep patterns for visitors not accustomed to it. Roads are significantly quieter between 10 p.m. and 6 a.m., making evening and early-morning driving both safer in terms of congestion and often the most rewarding experience of the trip.
