Where is Þórsmörk and Why is it so Special?

Have you ever dreamed of standing in a hidden valley surrounded by glaciers, volcanic mountains, and endless hiking trails? Welcome to Þórsmörk (pronounced Thorsmörk), one of Iceland’s most treasured nature reserves and a true paradise for adventurers. 

In this article, we’ll uncover where Þórsmörk is located, why it’s so unique, the best ways to get there, and the unforgettable experiences you can have—whether you’re hiking from Seljalandsfoss, joining a guided tour, or spending the night under a sky of countless stars.

Where is Þórsmörk?

Þórsmörk – meaning Thor’s Valley – lies in the southern Highlands of Iceland, tucked between three mighty glaciers: Eyjafjallajökull, Mýrdalsjökull, and Tindfjallajökull. This dramatic location creates a sheltered microclimate where lush birch forests, moss-covered lava fields, and winding glacial rivers flourish. It’s one of the rare places in Iceland where green valleys meet icy peaks, creating a landscape that feels both otherworldly and welcoming.

This remote area is part of the Icelandic Highlands, which means it’s only accessible via mountain roads (F-roads) during summer, usually from late May to early September. In winter, heavy snow and swollen rivers make it nearly impossible to reach without specialized vehicles – Super Jeeps, as we call them.

Why is Þórsmörk so Special?

The magic of Þórsmörk lies in its contrasts. You can hike through gentle birch forests, hear birdsong echo across green meadows, and then look up to see towering ice caps and jagged volcanic ridges. The area is known for:

  • Stunning panoramic views over glaciers, volcanoes, and valleys.

  • Unique microclimate, often warmer and sunnier than surrounding regions.

  • Rich biodiversity, with many plants and birds not commonly found in other parts of Iceland.

  • Folklore and legends, especially stories tied to Norse mythology and Thor, the god of thunder.

It’s also a beloved destination for Icelanders themselves, it is a wonderful area for locals and tourists! 

Hiking Trails in Þórsmörk

If there’s one thing that defines Þórsmörk, it’s hiking. The valley is the endpoint of some of Iceland’s most famous trails, and a starting point for many more.

1. The Thorsmork Hike from Skógafoss

One of the most epic routes to Þórsmörk is the Fimmvörðuháls trail, starting at Skógafoss waterfall and ending in Þórsmörk.

  • Distance: ~25 km (15.5 miles)

  • Time: 10–12 hours for a full-day hike, or split into two days with an overnight stay.

  • Highlights: Dozens of waterfalls along the Skógá river, crossing between Eyjafjallajökull and Mýrdalsjökull glaciers, and walking past the newly formed craters Magni and Móði from the 2010 eruption.

This hike offers constantly changing landscapes—from lush lowlands to volcanic deserts and then into the green oasis of Þórsmörk.

2. Shorter Local Trails

If you’re not ready for a full-day trek, Þórsmörk has plenty of shorter hikes:

  • Valahnúkur – A short, steep climb with panoramic views over the valley.

  • Stakkholtsgjá Canyon – A stunning walk through a narrow canyon ending at a hidden waterfall.

  • Tindfjöll Circle – A longer loop with glacier views and river crossings.

No matter your fitness level, you’ll find a thorsmork hike that suits you.

How to Get to Þórsmörk

Reaching Þórsmörk is an adventure in itself. The valley is surrounded by unbridged rivers and rough mountain roads, so planning ahead is essential.

1. By Hiking from Skógafoss

As mentioned earlier, the Fimmvörðuháls trail from Skógafoss is a challenging but incredibly rewarding way to arrive. You’ll need to be prepared for a full day of trekking and river crossings. Many hikers choose to arrange transport for their luggage or a bus ride back afterward.

2. Bus from Hvolsvöllur

During summer, highland buses run from towns like Hvolsvöllur and Seljalandsfoss directly into Þórsmörk. These buses are equipped for river crossings and offer a scenic, relaxed way to get there.

3. Guided Tour in a Super Jeep

For the easiest and most adventure option, join one of the guided Super Jeep tours. You will experience the tricky river crossings and navigate the rough F-roads while you sit back and enjoy the views. Plus, the local guides share insider knowledge about Þórsmörk’s history, geology, and hidden spots that most visitors miss.

Spending the Night in Þórsmörk

One day is often not enough to fully enjoy this huge valley. Staying overnight gives you the chance to explore trails at a slower pace and experience the serenity of Þórsmörk when most day visitors have gone.

Accommodation options:

  • Mountain huts – Basic but comfortable, often with bunk beds, cooking facilities, and heating. Booking ahead is essential.

  • Camping – The Þórsmörk campsite is a fantastic base for hiking, with access to facilities and surrounded by breathtaking views.

  • Multi-day tours – Some guided trips include overnight stays, making logistics easy while still giving you the full experience.

At night, the valley becomes peaceful and quiet, and on clear evenings you can enjoy stargazing—or, later in the season, even the Northern Lights.

Folklore of Þórsmörk

The name Þórsmörk comes from Thor’s Valley, and Icelandic folklore says this dramatic landscape was blessed — and fiercely protected — by Thor, the Norse god of thunder. According to the sagas, Thor battled frost giants in the highlands, striking the ground with his hammer Mjölnir and splitting the earth to form the valley. The surrounding glaciers — Eyjafjallajökull, Mýrdalsjökull, and Tindfjallajökull — were said to be ice fortresses he raised to shield the valley from invaders.

Thor’s Watch

Perhaps the most enduring legend is that Thor still watches over his namesake valley. Some say sudden changes in the weather — a protective fog, a warm burst of sunshine, or a rumble of thunder in clear skies — are signs of Thor’s presence, guarding travelers from harm. Whether it’s divine protection or simply Iceland’s unpredictable climate, there’s no denying that Þórsmörk has a powerful, almost mystical energy.

The Hidden People (Huldufólk)

The Krossá River is more than just a waterway; in folklore, it’s the home of the huldufólk — the hidden people. Travelers were warned never to cross without asking permission or leaving a small gift, like a smooth stone or a pinch of food. Those who disrespected the river spirits risked sudden floods or becoming lost in a thick, disorienting fog. Some guides still greet the river quietly before leading tours across it.

The Small Demon of the Highlands

One lesser-known tale speaks of a mischievous small demon who once lived near the Krossá River. Unlike the terrifying devils of other myths, this one was more of a trickster — stealing supplies from travelers, untying their horses at night, and luring them toward the wrong trails with ghostly lights. According to legend, a passing priest eventually trapped the demon inside a boulder using holy runes. Some hikers claim that when the wind is right, you can still hear faint scratching from inside the stone.

Unicorn Mountain (Einhyrningur)

Near Þórsmörk rises a distinctive peak locals call Unicorn Mountain, or Einhyrningur. The name comes from its sharp, horn-like summit, but folklore says it was once a real unicorn who roamed the valley. When hunters came too close, the unicorn fled to the mountains, where a sorcerer turned it to stone to protect it from harm. On misty days, the “horn” seems to pierce the clouds, making it easy to imagine the creature frozen mid-run.

The Cave Elf Church

Deep in one of the surrounding ridges lies a cavern that locals call the Elf Church. This natural lava cave has smooth walls and a dome-like ceiling that make it look like a tiny cathedral. Folklore says it’s where elves gather for important ceremonies, safe from human eyes. Travelers who enter are advised to be respectful and quiet — some say those who make too much noise inside hear whispers in the dark or feel a cold breeze with no source.

The Cave of the Fugitive

One of Þórsmörk’s most dramatic stories is about a man who fled into the highlands to escape justice. He found a hidden cave high above the valley, where he lived for months, surviving on river fish and the occasional sheep he stole from nearby farms. Some say the man eventually disappeared into the glacier itself, swallowed by an ice cave during a summer melt. Today, adventurous hikers sometimes try to find the Cave of the Fugitive, but it remains elusive — as if the valley still protects its secrets.

Must-See Spots in Þórsmörk

Even if you have just one day, don’t miss these highlights:

  • Valahnúkur viewpoint – Possibly the best panoramic spot in the valley.

  • Krossá River crossings – Thrilling to watch (and cross) with the right vehicle.

  • Stakkholtsgjá Canyon – A fairytale-like walk ending at a hidden waterfall.

  • Eyjafjallajökull volcano views – Best seen from high ridges on clear days.

  • Seljalandsfoss – While technically outside Þórsmörk, this waterfall is often included on the journey there and is a must-see.

Þórsmörk is more than a hiking destination—it’s a living piece of Iceland’s natural and cultural heritage. Whether you’re drawn by the challenge of the thorsmork hike from Skógafoss, the beauty of Seljalandsfoss along the way, or the peace of camping in a birch forest under glacier peaks, this valley will stay with you long after you leave.

Plan your trip, pack your hiking boots, and let Þórsmörk reveal its wonders—one trail, river, and breathtaking view at a time.
