A Self-Drive Guide to Visiting Askja

Deep within the remote, lunar-like landscapes of the Icelandic Highlands lies Askja, a destination that promises one of the most profound and unforgettable adventures Iceland has to offer. This massive volcanic caldera, home to a serene lake and the otherworldly Víti crater, is a place of raw, untamed beauty. Reaching it is a challenge, but the reward is an experience that connects you directly to the powerful geological forces of our planet.

A self-drive journey to Askja is not for the faint of heart, but with careful planning and the right vehicle, it is an achievable and incredibly rewarding expedition. This guide will provide the essential information you need to plan your trip, covering everything from navigating the formidable F-roads to understanding the unique wonders that await. Discover how a capable 4x4 rental from Höldur can be your key to unlocking this remote corner of Iceland.

What is Askja?

Askja is a complex of nested calderas located in the Dyngjufjöll mountains, part of the vast Ódáðahraun lava field—the largest in Iceland. The area is a result of immense volcanic activity over thousands of years. The main caldera was formed during a massive eruption in 1875, an event so powerful its ash traveled as far as mainland Europe.

Following this eruption, the caldera floor collapsed and began to fill with water, creating Öskjuvatn, one of Iceland’s deepest lakes. Beside it is Víti, a smaller explosion crater whose name translates to "Hell." Despite its name, Víti holds an ethereal, milky-blue geothermal lake that has become one of the most iconic sights in the Highlands.

The Challenge and Reward of a Self-Drive Trip

The journey to Askja is as much a part of the adventure as the destination itself. Located deep in the interior, it is accessible only via Iceland's rugged F-roads (mountain roads). These are unpaved, often rough tracks that involve multiple unbridged river crossings. This is not a journey for a standard car; it requires skill, preparation, and a capable vehicle.

The reward for undertaking this journey is access to a landscape that feels truly removed from the modern world. The solitude, the vastness of the volcanic desert, and the sheer scale of the caldera create a humbling and awe-inspiring experience. A self-drive tour gives you the freedom to travel at your own pace, stopping to absorb the stark beauty of the Highlands along the way.

Mandatory Vehicle: The 4x4

Let's be clear: a 4x4 rental in Iceland is not just recommended for a trip to Askja—it is a legal requirement. F-roads are legally off-limits to all 2WD vehicles. You need a robust 4x4 with high clearance to safely handle the rough terrain and, most importantly, the river crossings.

Höldur offers a wide selection of powerful 4x4 vehicles specifically suited for Highland adventures, such as the Toyota Land Cruiser or Dacia Duster. By picking up your vehicle from our convenient locations at Keflavik International Airport or in Central Reykjavik, you can begin your expedition fully equipped for the challenge ahead.

Planning Your Journey to Askja

A trip to Askja requires more planning than a typical day tour. The Highlands are an unforgiving environment, and you must be self-sufficient.

When to Go: The Short Summer Window

Askja is only accessible during a brief period in the summer, typically from late June or early July until late September or early October. The exact opening and closing dates of the F-roads depend entirely on snowmelt and weather conditions. Always check the official road status on umferdin.is before and during your trip.

The Routes: F88 and F910

Two primary F-roads lead to Askja from the Ring Road (Route 1):

• F88 (Öskjuleið): This is the more direct northern route. It is known for its challenging river crossings, including a formidable ford across the Grafarlandaá river. This route should only be attempted by experienced drivers in large, high-clearance 4x4s.
• F910 (Austurleið): Approaching from the east, this route is longer but is generally considered the "easier" of the two, with river crossings that are typically less deep than those on the F88. However, conditions can change rapidly, and it still presents a significant challenge.

For most self-drive travelers, the F910 is the more prudent choice. No matter which route you take, a full day is required for the round trip from the Ring Road.

What to See and Do at Askja

Once you arrive at the Vikraborgir car park, a 2.5-kilometer (1.6-mile) walk across a stark lava field brings you to the edge of the caldera.

Öskjuvatn Lake

The first sight to greet you is the vast, deep-blue expanse of Öskjuvatn. This lake fills the main caldera and, with a depth of over 220 meters, is the second deepest in Iceland. Its serene surface stands in stark contrast to the violent eruption that created it.

The Víti Crater

Nestled beside Öskjuvatn is the main attraction for many: the Víti crater. This smaller crater holds a geothermal lake with an opaque, turquoise-blue color and a temperature of around 25°C (77°F). A steep, sometimes slippery path leads down to the water's edge.

On calm, warm days, it is possible to bathe in Víti's mineral-rich waters. However, be aware that the path down is very steep, and the mud at the bottom can be slippery and hot in places. There are no changing facilities, so this is a truly wild bathing experience.

Essential Safety Precautions

Safety is paramount when traveling in the Icelandic Highlands.

• Check Conditions Daily: Before you set out, check road.is for road status and vedur.is for the weather forecast. Conditions can change in an instant.
• Know How to Cross Rivers: Never cross a river without first assessing its depth and current. If you are unsure, wait for another vehicle to cross. Cross slowly, in a low gear, and aim slightly downstream.
• Travel with a Full Tank: There are no fuel stations in the Highlands. Fill up your tank before you leave the Ring Road.
• Pack Accordingly: Bring warm, waterproof layers of clothing, sturdy hiking boots, food, and water for the entire day. The weather at Askja can be cold and windy even in summer.
• File a Travel Plan: For added safety, file your travel plan with SafeTravel.is. This allows authorities to know your intended route and schedule.

FAQs About Visiting Askja

How long does it take to drive to Askja?

Plan for a full day (10-12 hours) for the round trip from the Ring Road. The driving is slow, and you will want several hours at the caldera itself.

Can I drive to Askja in a small SUV?

While some small 4x4 SUVs can handle easier F-roads, the routes to Askja, with their significant river crossings, demand a large, high-clearance 4x4. It is essential to choose a vehicle from the appropriate category.

Is it safe to swim in Víti?

While many people do, it comes with risks. The path down is very steep, and high levels of sulfur gas can occasionally accumulate near the water's surface, which can be dangerous. Assess the conditions carefully before entering.

Are there any facilities at Askja?

There are basic toilet facilities at the Dreki huts (located along the F910) and near the main car park at Askja. There are no shops, restaurants, or fuel stations.

 

A journey to Askja is the ultimate Icelandic road trip, an expedition that rewards preparation and a spirit of adventure with an unparalleled connection to nature. With a reliable 4x4 from Höldur, you can confidently embark on this journey into the heart of Iceland’s volcanic wilderness.
