Tunnel Vision: Iceland’s Most Spectacular Underground Roads
If you are planning to visit Iceland for the first time, you’re in for a treat because driving there is a once-in-a-lifetime experience. Iceland’s roads are unlike any you’ll find across the world. But not all interesting things are seen above ground, and nestled beneath the surface, you will find some very interesting tunnels in Iceland, and one of them even features a crossroad in its depths! These make getting around Iceland that much easier, but it’s important to know what you’re getting into with each one.
There are currently 14 operating road tunnels in Iceland, with the 10 major ones listed below. Experience a novel side to Icelandic roads as you drive through them on your travels. Here, we’ve put together a guide to Iceland’s tunnels, including maps to highlight locations and other key information to bear in mind about each tunnel.
Map of Tunnels in Iceland
If you’re planning a road trip around Iceland, it’s helpful to know if you’ll encounter any tunnels on your route. This map of Iceland’s tunnels should help you get an idea of whether or not your planned route will lead you through any of these tunnels.
1. Héðinsfjarðargöng – The Longest Tunnel in Iceland
Iceland’s longest tunnel offers an easy drive from Ólafsfjörður to Siglufjörður. It was finished in 2010 and is 11,000 meters long (6.83 miles). You can find it north of Akureyri in North Iceland. The tunnel opens up in Héðinsfjörður after 7.1 kilometers (4.4 miles) and then continues another 3.9 kilometers (2.4 miles) to Siglufjörður.
Driving through the tunnel is toll-free, like all tunnels in Iceland (except for Hvalfjarðagöngurinn and the new tunnel north of Akureyri).

2. Breiðadals and Botnsheiði Tunnels – The Crossroads Wonder
Officially opened in 1996, the Breiðadals tunnel is 9.120 m long (5.66 miles). Only 2 kilometers of the tunnel have two lanes going in each direction. The rest is only one lane wide.
Located west of Ísafjörður in the Westfjords, this is the Icelandic tunnel with a crossroad set inside it. You might encounter traffic going south from Suðureyri while driving through this magnificent tunnel. It’s a well-lit tunnel and paved all the way, so just enjoy the ride in your Iceland rental car. When meeting oncoming traffic in a one-lane tunnel, don’t worry – there will be passing places. If the passing place is on your side of the tunnel, you are obligated to turn in and let oncoming traffic pass you. Speed limits are in effect in the tunnels, with cameras being well-marked to prevent any speeding offenses.

3. Bolungarvíkurgöng – The Fjord Connector
This tunnel north of Ísafjörður opened in 2010 and is 5.400 meters long (3.36 miles). It is a two-lane tunnel with traffic going both ways. It’s well-lit and easy to drive. If you are in Ísafjörður, you can drive north to Hnífsdal, where you enter the tunnel to Bolungarvík.

4. Arnardalshamar – Iceland’s Oldest Tunnel
The first tunnel ever built in Iceland, Arnardalshamar, is 30 meters (98 feet) long and has two lanes. You will pass through it when you drive between Ísafjörður and Súðavíkur, which will allow you to enjoy a stunning journey.

5. Strákagöng – The Short Sprint
Strákagöng lies in the north of Iceland. This tunnel opened in 1967 and is 800 meters long (1/2 mile). It is a single-lane tunnel, and the same rules apply as in all single-lane tunnels in Iceland; if you meet oncoming traffic and the passing place is on your side (your right), you are required by law to stop and let the oncoming traffic pass by.

6. Múlagöng – The Arctic Gateway
Múlagöng is located north of Akureyri. It’s the tunnel connecting Dalvík to Ólafsfjörður. It opened in 1990 and is 3,400 meters long (2.11 miles). This is a one–lane tunnel with passing places.

7. Hvalfjarðargöng – The Seabed Serpent
Hvalfjarðargöng, just north of Reykjavík, is a tunnel that goes under the fjord Hvalfjörður. It’s 5,770 meters long (3.59 miles), with 3,750 meters (2.33 miles) of the tunnel lying beneath the seabed. There are two lanes on the south side (closer to Reykjavík) and three lanes going north. The deepest part of the tunnel reaches a depth of 165 meters (541 feet).
There are lay-bys in the tunnel, but those are only for emergencies. There are also speed cameras in the tunnel to catch any speeding offenses, so make sure to drive carefully at all times. About a decade ago, it was the only tunnel in Iceland where you’d have to pay a toll. The toll booth is on the north side of the tunnel, so when heading north, pay your toll upon exiting the tunnel. Information about toll prices can be found below.

There are over 80 cameras guarding the tunnel 24/7, and you have both FM (RÚV on 93.5 & 90.1 Bylgjan on 98.9) and mobile phone reception in the tunnel. Just to mention a few more safety features:
- There are fire extinguishers and emergency phones every 125 m (410 ft).
- The tunnel has 40 powerful fans to blow out exhaust gases.
- The staff in the toll booths guard all aspects of the tunnel at all times.
- There are safety lights on the ceiling every 50 meters (164 feet).
- There are emergency lights every 62.5 meters (205 feet) that turn on if there is a blackout.

8. Oddsskarð – The Mountain Tunnel
Oddsskarð tunnel lies north of Eskifjörður and leads to Norðfjörður. It is 640 meters (0.4 miles) long and only has one lane. The tunnel is free of charge and has plenty of passing places. It opened in 1977 and is 600 meters above sea level.

UPDATE: This tunnel has been decommissioned for day-to-day use. A new tunnel has been opened just northwest of Eskifjörður.
8b. Norðfjarðargöng – The New Frontier
Norðfjarðargöng is 7.5 kilometers (4.66 miles) long. It is taking over the traffic that previously passed through Oddsgarð. It is very well-lit, has lanes in both directions, and the feeling while driving it is something unique.

9. Fáskrúðsfjarðargöng – The Eastern Artery
Fáskrúðsfjarðargöng is 5.900 meters (3.67 miles) long and opened in 2005. It has lanes going in both directions.

10. Almannaskarðsgöng – The Southern Connector
Almannaskarð tunnel opened in 2005 and is 1.300 meters (0.8 miles) long. This one also has lanes going in both directions. This tunnel connects the south side of Iceland with the East side. There used to be a difficult connecting road, but with the opening of this tunnel, driving to the east side has become so much easier. The south entrance is located 39 meters (128 feet) above sea level, whilst the north entrance is 82 meters (269 feet) above sea level, giving the tunnel an incline of 4.6%.

We are sure you will enjoy the ride through many of these tunnels. When you rent a car with Go Iceland Car Rental, each rental car contains a map of where you can find these tunnels. We also sell a much more detailed map at our offices. Please let our staff assist with any questions you might have about your drive around Iceland, from recommendations to directions.
