Hekla Volcano

In the Middle Ages, this volcano was known as the “Gateway to Hell.” It’s one of the most famous volcanoes in Iceland and the most active in the country.

Hiking in this mighty place is not easy, but it’s one of the most rewarding experiences. Here, you can take a look at the raw power of Icelandic nature. From the summit, the views are breathtaking. On a clear day, you can see all the way to the glaciers of Vatnajökull and Mýrdalsjökull.

Eldgjá Canyon

When talking about dramatic landscapes, it’s impossible not to mention Eldgjá. The name means Fire Canyon, and it’s the world’s largest volcanic canyon.

It was formed by a massive volcanic eruption that occurred more than 1,000 years ago. It stretches over 40 kilometers (25 miles) and offers great views full of cliffs and waterfalls. Of the latter, a great recommendation is to hike up to Ófærufoss, a beautiful cascade inside the canyon.

Exploring By Foot or Hoof

The most popular way to visit Fjallabak Nature Reserve is by foot. The many hiking trails in the area make it a great option to enjoy everything that’s in here. But that’s not the only way.

A great way to discover Fjallabak is by riding an Icelandic horse. These magnificent creatures are among the best-known animals in the country. They are small but strong, friendly, and easy to ride. Many horses are domesticated, and tours are available to visit several places in Iceland, including Fjallabak.

You can also encounter them grazing around in the fields. If so, you can get closer and take pictures of them, but try not to pet them. They are calm and nice horses, but you never know how a wild animal can react.

Where's Fjallabak and how to get there?

We’re going to take the capital, Reykjavik, as the starting point in this instance, as it’s the most common beginning of all the routes that lead to the reserve. And that's because getting to Fjallabak is an adventure in itself. Located in the southern highlands of Iceland, the reserve is about a three-hour drive from Reykjavik.

It's important to take into consideration that this journey is not your typical road trip. To reach Fjallabak, you’ll need to tackle Iceland's F-roads. These roads can be rugged, unpaved tracks that go through many places in the country, especially the Central Highlands.

Driving to Fjallabak

The best option for visitors is renting a car to reach Fjallabak. As some parts of the route can be challenging, a 4x4 vehicle is almost mandatory. Apart from the state of the mentioned F-roads, driving there often involves crossing a river. So, a car that can adapt to different conditions can make the difference between a thrilling adventure and a frustrating journey.

If you are going to Fjallabak Nature Reserve from Reykjavik, the most common route is taking the F208 from the Ring Road (Route 1)– This drive offers great views, but you should drive carefully. Alternatively, you can take the F225, which is slightly more challenging but also quite rewarding.

It’s important to remember that the climate can affect the roads in Iceland. Snow and other weather elements can force the authorities to close some roads, especially F-roads. Check the road status before departing for your destination.
