Borgarvirki, Iceland: Complete Guide to the Natural Basalt Fortress

Picture a rocky stronghold rising out of Iceland’s rough landscape, where old stories and volcanic rock come together in a place most people drive right past. Borgarvirki is where real battles once happened, where well-known legends took shape, and where you can step into Iceland’s past without the noise of the more crowded sights.

This volcanic plug on the Vatnsnes Peninsula isn’t just a cool formation. It’s a place where history feels close, and the views stretch out in every direction.

What is Borgarvirki?

Borgarvirki means “citadel” and rises 177 meters above sea level on the Vatnsnes Peninsula. It is the hard core of an old volcano, shaped into tall basalt columns that form natural walls 10 to 15 meters high. Early Icelanders added stone walls, a gate, and small living areas. Inside is a grassy hollow with the remains of two huts and a small well.

The History and Legends of Borgarvirki

Borgarvirki dates back to the Settlement era between 870 and 1030 and appears in old Icelandic stories. It was likely used as a defensive stronghold during the violent Age of the Sturlungs in the 13th century. Its steep sides and single main entrance made it easy to defend. One famous saga tells of a siege around the year 1000 that later inspired an Icelandic saying.

Geological Wonder: A Natural Fortress

Borgarvirki formed when magma cooled inside a volcano and the softer rock around it eroded away. This left behind strong hexagonal basalt columns stacked into steep cliffs. The shape created a naturally raised and protected site. Inside are stone remains, a well, and open space once used for shelter.

Location and How to Get to Borgarvirki

Borgarvirki is on the Vatnsnes Peninsula in northwest Iceland, about 10 kilometers off Route 1. It is around 218 kilometers from Reykjavik and 182 kilometers from Akureyri. Reaching it requires a short drive on Routes 716 and 717. The final stretch is gravel but usually manageable in summer.

What to Expect When You Arrive

There is a small parking area and an information sign, but no services. The walk to the top is short, about 200 to 300 meters, and takes 5 to 10 minutes. The ground inside is uneven, and the edges are steep with no barriers. The nearest town with facilities is Hvammstangi, about 30 kilometers away.

Best Time of Year to Visit Borgarvirki

Summer is the easiest time to visit, with mild temperatures around 10 to 15°C and long daylight hours. Spring and autumn are quieter but colder and less predictable. Winter travel can be difficult due to snow and road conditions. Clear winter nights can offer good chances to see the northern lights.

Visitor Tips and Practical Advice

Weather can change quickly and there are no nearby services. Warm layers, waterproof clothing, and sturdy shoes are important. The cliffs drop sharply, so visitors should stay well back from the edges. Bringing water and snacks is recommended.

Top Things to Do at Borgarvirki

From the top, you get wide views over Lake Vesturhóp, the Víðidalur valley, and Húnaflói Bay. Visitors can explore the interior and see the stone outlines of huts and the small well. The basalt formations and open landscape are great for photos. A short walk along the inner rim gives different viewpoints.

What is Borgarvirki?

Borgarvirki means “citadel,” and you’ll understand the name as soon as you see it. It stands 177 meters above sea level and overlooks much of the Vatnsnes Peninsula in northwest Iceland.

The formation is the solid core of an old volcano, built from tall basalt columns that look a lot like walls someone decided to stack on purpose. These cliffs rise 10 to 15 meters high, and early Icelanders took full advantage of that natural shape by adding stone walls, a gateway, and simple living spaces.

Inside, there’s a round depression with the remains of two huts and a small well. The entrance is on the eastern side and leads you into a grassy interior where people lived and tried to protect themselves centuries ago.

The history and legends of Borgarvirki

Borgarvirki shows up in several old Icelandic stories, which makes sense since the site traces back to the Settlement era between 870 and 1030.

Viking-age and medieval significance

People believe Borgarvirki was used as a real defensive site during the Age of the Sturlungs in the 13th century, a time when Iceland was filled with conflict. From the top, you could easily see anyone approaching, and the steep sides gave natural protection. Only the eastern entrance needed careful guarding.

Settlers built up the weak spots with more stone walls and added small shelters inside. Up to 150 people could stay here during a siege.

Folklore and saga connections

One of the most well-known stories comes from the Heiðarvíga Saga and involves Víga-Barði (Killer-Barði). Around the year 1000, he and his men were said to have held out here during a two-week siege.

When they were almost out of food, they threw their last piece of sheep fat over the wall to trick the attackers into thinking they had plenty left. It worked, and the attackers left. That moment inspired an Icelandic saying, “að kasta út mörsiðrinu,” which means taking a bold gamble when you’re nearly out of options.

Restoration and preserved archaeology

Borgarvirki became one of the first places in Iceland to be officially protected in 1817. Larger repairs happened in 1949 and 1950, when workers rebuilt sections of the stone walls and added a granite lintel above the entrance. Today, you can still see the old foundations, the restored walls, and the small well that shows how people survived here during long standoffs.

Geological Wonder: A Natural Fortress

Understanding how Borgarvirki was formed makes it easier to see why people chose it as a stronghold and why it appears the way it does now.

What a volcanic plug is

Long ago, magma rose through a volcano and cooled inside the central vent. Over thousands of years, wind and rain wore away the softer outer rock, leaving behind the rigid core. As the lava cooled, it cracked into hexagonal basalt columns that stacked neatly into tall, geometric shapes.

Basalt columns forming “castle walls”

These columns rise 10 to 15 meters high and create steep walls that are hard to climb. The entire formation gives you a naturally raised platform with steep sides and only one sensible way in.

Interior features: stone remnants, old well, panoramic lookout

Inside the walls, the depression provided shelter for huts and storage. Archaeologists have found the outlines of two dwellings and a small well that would have been essential during sieges. On top, you’ll also find a viewing dial added in 1990 that points out the major landmarks in the distance.

Location and How to Get to Borgarvirki

Borgarvirki sits on the Vatnsnes Peninsula in northwest Iceland, about 10 kilometers off the Ring Road (Route 1). It’s roughly 218 kilometers from Reykjavik and 182 kilometers from Akureyri.

Short detour from Route 1 via Routes 716 and 717

From Reykjavik, take the Ring Road (Route 1) north for about 3 hours, pass through Blönduós, and follow the signs for Borgarvirki. Turn left onto Route 716, drive about 7 kilometers, then switch to Route 717.

From Akureyri, head west and south on Route 1 for about 2.5 hours. Turn right onto Route 716 around 15 kilometers after Víðidalstunga.

Accessible for most cars in summer; gravel road conditions noted

The last 3 kilometers on Route 717 are gravel. In dry summer weather, most cars can handle it. In wet conditions or if you’re driving a campervan, a 4WD is safer. Drive slowly, be ready to move aside for oncoming cars, and check winter road conditions since snow can block access.

What to Expect When You Arrive

Borgarvirki is quiet and straightforward. There’s no visitor center, no shop, and usually not many people.

A small parking area and an information board sit at the base. The walk to the top is short, around 200 to 300 meters, and most people reach the summit in 5 to 10 minutes. The steps and rocks are uneven, so good shoes help.

Walking through the old gateway feels like you’re stepping into a different moment in history. Inside, the ground is uneven, and the edges are steep with no barriers, so move carefully and watch your footing.

There are no restrooms or services. Hvammstangi, about 30 kilometers away, is your closest option for food or facilities.

Best Time of Year to Visit Borgarvirki

The time of year makes a big difference in how easy it is to reach the site and what kind of conditions you’ll find.

Summer: ideal weather and long days

June through August gives you the easiest visit, with mild temperatures around 10 to 15°C and long daylight hours.

Spring and Autumn: quieter seasons with cooler weather

April to May and September to October have fewer visitors and pretty seasonal colors. Weather can be cooler and more unpredictable, so check road conditions and dress warmly.

Winter: only for prepared travelers, possible aurora views

Winter visits require caution. Temperatures usually range from -5 °C to 5°C; snow is common, and the road may not be drivable. On clear nights, though, this remote spot is great for seeing the Northern Lights.

Visitor Tips and Practical Advice

Borgarvirki sits in a quiet, wide-open part of Iceland where the weather changes quickly, and there are no services nearby. A little preparation goes a long way here, especially if you’re not used to hiking on uneven volcanic rock. With the right layers and some basic supplies, the visit is simple, safe, and much more fun.

Clothing and layering for wind and weather

Bring layers, even in summer. A waterproof jacket, a warm layer, a hat, and gloves make a big difference at the top, where it often feels colder.

Footwear recommendations

Wear sturdy shoes or hiking boots. The rocks can shift a bit underfoot, and the path gets slippery when wet.

Safety on steep edges

The drop-offs around the edges are sharp. There are no railings, so keep a safe distance and stay close to children.

Bring water and snacks

There’s nowhere nearby to buy anything. Bring water, snacks, and maybe a warm drink if the weather is chilly.
