Vatnafjöll Volcano System

Vatnafjöll is a volcanic system tucked away in south Iceland, next to the more famous Hekla volcano. Its name, which translates to "Water Mountains,"  is actually a contradiction because the area is characterised by a lack of water; there are no lakes and no rivers or streams. Every drop of rain disappears into the porous bedrock and merges with the groundwater.

Stretching roughly 40 kilometres in length and around 9 kilometres wide, Vatnafjöll is composed of a long fissure system and over twenty volcanic craters, most of them now quiet, but the entire region is still considered active.

Where is Vatnafjöll Located?

You’ll find Vatnafjöll in Iceland’s southern Highlands, a wild and scenic region filled with lava fields. The volcano system sits just southeast of Hekla, about 130 kilometres from Reykjavík. It’s also around 40kilometres northeast of Hella, a small town that serves as a base for exploring this part of the country.

While it’s not as easy to access as other popular sites like the Golden Circle or South Coast attractions, Vatnafjöll rewards those who make the effort. The area feels remote and untouched, offering panoramic views, silence, and space to breathe.

Why a Visit to Vatnafjöll is Worth it

Vatnafjöll offers something that many other sites in Iceland don’t: seclusion. Here, there are no tour buses, no crowds, and no souvenir stands. Just volcanic ridges, dormant craters and windswept lava plains.

While it's off the beaten path, Vatnafjöll pairs well with a visit to Perlan in Reykjavík, where you can learn more about Iceland's volcanoes and how they shape the land. To explore more about Iceland’s volcanic activity, check out this article about active volcanoes in Iceland.

What to Do in Vatnafjöll

Unlike many other nature spots in Iceland, Vatnafjöll has no visitor centre, gift shop, or paved trails. What it does have is space, silence, and volcanic beauty. Hiking is the main draw here. You can explore craters, ridgelines, and lava fields at your own pace, often without seeing another person for hours.

Photographers will appreciate the dramatic contrasts of black lava, green moss, and distant snow-capped peaks. The terrain can be challenging, so sturdy shoes and weatherproof gear are a must. And since there’s no shelter or services, bring everything you’ll need, including food, water, and warm clothing.

The area is also interesting for anyone who wants to get a close look at Iceland’s geological features. You’ll see how past eruptions shaped the land, with some lava flows still looking as fresh as if they cooled yesterday.

Learn More at Perlan Before You Go

If you’re in Reykjavík, a visit to Perlan is a great starting point to learn about Volcanoes like Vatnafjöll. Perlan features hands-on exhibits and immersive experiences that help explain Iceland’s volcanic systems, including how places like Vatnafjöll and Hekla were formed.

At Perlan, you can step into a real ice cave, watch a volcano erupt in a 360° show, or learn about tectonic plates and magma chambers. It’s a fun and educational way to get a deeper understanding of what you’re seeing when you visit Iceland’s volcanic landscapes.

Before You Go

Vatnafjöll isn’t polished, and that’s part of its charm. There are no marked trails or man-made paths, just the raw landscape and the freedom to explore. This makes it an excellent spot for seasoned hikers and curious travellers looking to get off the main tourist track.

The best time to visit is during the summer, from late June to early September. During this period, the roads are open, the weather is more stable, and you’ll have more daylight to explore. Just remember to leave no trace and respect the delicate highland ecosystem.

You can learn more about how Iceland’s volcanoes form and erupt at the Volcano Show, an immersive exhibit that explains the forces shaping the island.
