Fjallabak Nature Reserve: A Self-Drive Guide to Iceland’s Rugged Highlands

Iceland is home to some of Europe’s most wild and untamed landscapes, and few places embody this spirit more than the Fjallabak Nature Reserve. Located deep in the Southern Highlands, Fjallabak—which translates to "Mountain's Back"—is a realm of surreal beauty, defined by its vividly colored rhyolite mountains, vast volcanic deserts, steaming geothermal vents, and hidden lakes. This is not the Iceland of the Ring Road; this is a challenging and profoundly rewarding region accessible only to the well-prepared.

A self-drive journey into Fjallabak is the ultimate Icelandic adventure, a true exploration into the heart of the island’s geological wonders. This guide provides the essential information needed to plan a safe and successful trip, covering road access, vehicle requirements, key attractions like Landmannalaugar, and the best time to visit. With a capable 4x4 rental from Höldur, you can unlock one of the most spectacular destinations on the planet.

What is the Fjallabak Nature Reserve?

Established in 1979, the Fjallabak Nature Reserve covers approximately 47,000 hectares of Iceland’s Southern Highlands. The area is a masterpiece of volcanic artistry, shaped by millennia of eruptions and glacial activity. Its unique geology is the main draw, offering landscapes that feel more like another planet than Earth.

Key features of the reserve include:

• Rhyolite Mountains: The region is famous for its mountains made of rhyolite, a type of volcanic rock that oxidizes to create a stunning palette of red, pink, orange, green, and gold. This is most famously seen in the Landmannalaugar area.
• Geothermal Activity: The ground in Fjallabak is alive. You will find steaming fumaroles, bubbling mud pots, and natural hot springs, a direct result of the area's position on the Mid-Atlantic Ridge.
• Volcanic Landscapes: The reserve is dominated by obsidian lava fields, vast plains of black volcanic ash (sandur), and craters. The nearby Hekla volcano, one of Iceland’s most active, has heavily influenced the terrain.

The centerpiece of Fjallabak is Landmannalaugar, a geothermal oasis nestled among the colorful mountains. It serves as a base camp for hikers and explorers and is the starting point of the world-renowned Laugavegur hiking trail.

Planning Your Self-Drive Expedition into Fjallabak

Reaching the Fjallabak Nature Reserve is an adventure in itself and requires careful planning. The region is accessible only via rugged mountain roads known as F-roads.

The Essential Vehicle: A Capable 4x4

There is no ambiguity here: a 4x4 vehicle is mandatory to enter the Fjallabak Nature Reserve. The F-roads are unpaved, extremely rough, and often involve crossing unbridged rivers. Attempting to drive these routes in a standard 2WD vehicle is not only illegal and dangerous but also voids all rental insurance.

When selecting your vehicle, consider a robust 4x4 with high ground clearance. This will provide the capability and durability needed to handle river crossings and navigate the challenging terrain safely and comfortably. Höldur Car Rental offers a comprehensive fleet of 4x4s suitable for the Highlands, ensuring you have the right equipment for the journey. You can start your adventure fully prepared by picking up your vehicle at our convenient locations, including the arrivals hall at Keflavik International Airport or in Central Reykjavik.

Access Routes and F-Roads

There are three main F-roads that provide access to Landmannalaugar:

1. F208 from the North (Easiest Route): This is the most common and accessible route. It does not have any major river crossings, making it suitable for all types of 4x4s. The road is gravel and can be heavily corrugated but is manageable for any driver comfortable with unpaved roads.
2. F225 from the West (Hekla Route): This scenic route takes you past the mighty Hekla volcano. It involves several small to medium-sized river crossings and offers stunning views of the volcanic landscape.
3. F208 from the South (Most Challenging Route): This section of the F208, coming from the Ring Road near Vík, is one of the most demanding F-roads in Iceland. It involves crossing several deep and dangerous rivers. This route should only be attempted by experienced drivers in a large, highly capable 4x4. This route poses a high risk of water damage and is not recommended for rental cars.

Crucial Safety Note: River conditions can change rapidly depending on rainfall and glacial melt. Always check the water depth and current before crossing. If in doubt, wait for another vehicle or turn back.

Exploring the Wonders of Fjallabak

Once you arrive, a world of geological marvels awaits.

Landmannalaugar

This is the heart of the reserve. Here you will find a campsite, a basic mountain hut, and the "People's Pool"—a natural geothermal river where you can bathe with the colorful mountains as your backdrop. It is the primary hub for information and services in the area.

Hiking Trails

Fjallabak is a hiker's paradise. From Landmannalaugar, numerous trails fan out into the surrounding mountains.

• Laugahraun Lava Field: An easy 1-2 hour loop that takes you through a fascinating obsidian lava field and up to the slopes of Brennisteinsalda, the "Sulphur Wave" mountain.
• Bláhnúkur (The Blue Peak): A steep but rewarding hike to the summit of a blue-black volcanic mountain. The panoramic view from the top, overlooking the multi-colored landscape, is one of the best in all of Iceland.
• The Laugavegur Trail: For serious trekkers, this is the start of the famous 55-kilometer multi-day hike to Þórsmörk.

Other Notable Sights

• Ljótipollur Crater Lake: The name translates to "Ugly Puddle," but it is anything but. This explosion crater is filled with deep blue water, surrounded by striking red volcanic walls. It is a short drive or a longer hike from Landmannalaugar.
• Hrafntinnusker: A remote, obsidian-rich area deep within the reserve known for its ice caves that can sometimes persist into the summer. Hrafntinnusker is typically accessed via the Laugavegur trail. It's important to note that you cannot drive directly to Hrafntinnusker. The area is only reachable by hiking. The journey starts with a self-drive trip to the trailhead, most commonly Landmannalaugar.

Best Time to Visit and Practical Information

The window to visit Fjallabak is very short.

• Best Time to Visit: The F-roads leading into the reserve are typically open only from late June to early or mid-September. This period is entirely dependent on snowmelt and road conditions. Always check umferdin.is for the latest updates before planning your trip.
• Facilities: Services are extremely limited. There are basic toilets and a small "Mountain Mall" bus at Landmannalaugar selling essentials during the summer. You must be self-sufficient and bring all necessary food, water, and supplies.
• Fuel: There are no gas stations in the Highlands. The last place to fill up is on the Ring Road or in the towns leading to the Highlands. Ensure you have a full tank before heading in.

Frequently Asked Questions (FAQs)

Do I absolutely need a 4x4 for Fjallabak?

Yes. It is a legal requirement. The F-roads are specifically designated for 4x4 vehicles only. There are no exceptions.

Is it safe to drive in the Highlands?

It is safe if you are well-prepared. This means having the right vehicle, checking road and weather conditions obsessively, driving cautiously, and never underestimating the power of nature, especially when it comes to river crossings.

Can I visit Fjallabak as a day trip from Reykjavik?

While technically possible, it is not recommended. It involves a very long day of driving (at least 3-4 hours each way) on demanding roads, leaving little time for exploration. It is best to plan for at least one overnight stay, either camping or in the mountain hut (which must be booked far in advance).

What should I pack for a trip to Fjallabak?

Pack for all conditions. This includes waterproof and windproof outerwear, warm layers (fleece, wool), sturdy hiking boots, a hat, and gloves. Even in summer, the weather can be cold, wet, and windy.
