Exploring the Icelandic Highlands with a Guide

Navigating the pristine yet rugged terrain of the Icelandic Highlands calls for experience, the right vehicle, and a thorough understanding of the ever-shifting conditions. Many trails involve river crossings, steep mountain roads, and unmarked paths, making it highly advisable to journey with a professional guide.

Experienced guides not only ensure your safety but also enrich your exploration by sharing captivating stories, local legends, and invaluable insights into the region’s geological and cultural significance. Regardless of where you decide to tread in the highlands, a guided tour allows you to fully immerse yourself in this breathtaking landscape while leaving the logistics in capable hands.

Fjallabak Nature Reserve
Untamed Beauty in the Highlands

Located in the heart of the highlands, Fjallabak Nature Reserve is a sanctuary of towering mountains, black sand deserts, and verdant lava fields. The name “Fjallabak,” meaning “behind the mountains,” captures the essence of this wild and remote terrain.

Spanning 47,000 hectares, the reserve showcases an ever-changing landscape sculpted by volcanic activity and glacial erosion over millennia. Among its natural wonders are Mælifell Mountain, with its striking green slopes rising imposingly from the black sands of Mælifellssandur, and the tranquil Álftavatn Lake, a favorite nesting ground for migratory birds in summer.

As you venture into Fjallabak, you’ll discover that the scenery shifts dramatically from day to day, influenced by daily weather and road conditions. Those who dare to explore this remote area are treated to some of Iceland’s most breathtaking and lesser-known gems.

Highlights of Fjallabak Nature Reserve

Mt. Mælifell: This stunningly vivid green peak emerges sharply from the stark black volcanic sands of Mælifellssandur. Shaped by glacial floods and adorned with bright moss, it stands as one of the most photographed landmarks in the Icelandic Highlands.

Álftavatn Lake: A serene glacial-fed lake enveloped by undulating hills and jagged mountains. Renowned for its tranquility, the lake serves as a haven for migratory birds, especially whooper swans, hence its name (“Swan Lake”). It’s also part of the famous Laugavegur Trail, offering stunning reflections of the surrounding peaks on calm days.

Geothermal Hot Springs: Scattered throughout the Fjallabak Nature Reserve, these natural hot springs offer a rejuvenating retreat after a long day of hiking. The region’s geothermal activity brings forth steaming rivers, bubbling mud pots, and soothing warm pools—perfect for relaxing while surrounded by the untouched wilderness of the Highlands.

Þórsmörk
The Valley of Thor & A Hiker’s Paradise

Þórsmörk, a lush, glacial-carved valley nestled between three iconic glaciers—Eyjafjallajökull, Mýrdalsjökull, and Tindfjallajökull—is named after the Norse god of thunder. This verdant valley is a favorite among hikers and nature enthusiasts, boasting a wealth of scenic trails, towering ridges, and moss-covered canyons.

Getting to Þórsmörk is an adventure in itself. The journey requires a 4×4 vehicle to navigate the unbridged glacial rivers and rugged highland roads, but the reward is an undisturbed paradise where birch forests, ancient lava fields, and deep ravines contrast dramatically with the surrounding glaciers.

Þórsmörk’s unique microclimate results in a warmer and greener environment compared to other highland areas, creating a true oasis in the heart of Iceland’s wilderness.

Notable Hikes in Þórsmörk

Stakkholtsgjá Canyon: This narrow, dramatic ravine, carved through towering rock walls, leads to a stunning hidden waterfall. The short but rewarding hike through moss-covered cliffs and unique rock formations makes Stakkholtsgjá one of the most picturesque canyons in Iceland.

Valahnúkur Mountain: A relatively brief yet steep ascent that rewards hikers with breathtaking panoramic views over Þórsmörk, Mýrdalsjökull Glacier, and Eyjafjallajökull Volcano. On clear days, the stunning vistas extend all the way to the Westman Islands.

Fimmvörðuháls Pass: One of Iceland’s most iconic hikes, this demanding trek spans 24 km and connects Þórsmörk with Skógar, passing between the magnificent Eyjafjallajökull and Mýrdalsjökull glaciers. The route takes you past the new volcanic craters, Magni and Móði, formed during the 2010 eruption, before descending past the stunning Skógafoss Waterfall en route to the coast.

Landmannalaugar
A Geothermal Wonderland in the Highlands

Within the Fjallabak Nature Reserve lies Landmannalaugar, often referred to as the jewel of Iceland’s highlands. Its vibrant rhyolite mountains, steaming hot springs, and endless hiking trails present an enchanting landscape. After a day of exploration, visitors can relax in the natural hot spring at the valley’s base—a geothermal oasis with a rich history of use going back centuries.

Top Hikes in Landmannalaugar

Brennisteinsalda (Sulphur Wave): A moderate trek through the steaming fumaroles and vibrantly colored mineral-streaked mountains of Landmannalaugar. The brilliantly hued rhyolite slopes—painted in shades of yellow, red, green, and black—render this one of the most surreal environments in the entire highlands.

Bláhnúkur (Blue Peak): This hike is often paired with the ascent of Brennisteinsalda and presents a challenging climb to one of the most striking summits in Landmannalaugar. The deep blue-grey volcanic peak boasts breathtaking 360° views across the highlands, including views of the Fjallabak Nature Reserve and Hekla Volcano.

Laugavegur Trail: Recognized as one of the world’s premier multi-day treks, this 55 km path leads hikers from Landmannalaugar to Þórsmörk over four days. The journey showcases a breathtaking variety of landscapes, from geothermal valleys and black obsidian lava fields to crystal-clear lakes, vast black sand deserts, and lush birch forests.
