Fimmvörðuháls Pass: Laugavegur's Natural Extension

The Fimmvörðuháls Pass stands as one of Iceland's most spectacular mountain crossings, threading between the ice caps of Eyjafjallajökull and Mýrdalsjökull whilst connecting the famous Laugavegur trail to the coast. This 25-kilometre trek from Skógar to Þórsmörk offers hikers an extraordinary journey through landscapes shaped by recent volcanic activity, cascading waterfalls, and dramatic glacial formations.

A Path Between Fire and Ice

The name Fimmvörðuháls translates to "five cairns pass," referring to the ancient stone markers that once guided travellers across this challenging mountain route. At 1,116 metres above sea level, the pass creates a natural corridor between two of Iceland's most prominent ice caps, offering unparalleled views of both volcanic and glacial landscapes.

The trail gained international attention in 2010 when the Eyjafjallajökull eruption created new craters directly along the hiking route. The Magni and Móði craters, named after Thor's sons in Norse mythology, now provide hikers with the rare opportunity to witness geology in action, walking past lava fields that are barely a decade old.

The Complete Highland Experience

Skógar to Baldvinsskáli

The journey begins at Skógar Museum (elevation 60 metres), where hikers can park for 1,000 ISK per day. The trail immediately ascends alongside Skógafoss, following the Skógá River through a series of increasingly dramatic waterfalls. This first section gains 900 metres of elevation over 8 kilometres, passing more than 20 significant waterfalls carved into the basalt cliffs.

The path winds through birch scrubland before emerging onto the highland plateau, where the landscape transforms into a moonscape of black volcanic sand and scattered volcanic bombs. Weather conditions can change rapidly at this elevation, with visibility dropping to mere metres during cloud cover or storms.

The Volcanic Theatre

Between kilometres 12 and 16, hikers traverse the fresh lava fields created during the 2010 eruption. The Magni crater rises 60 metres above the surrounding terrain, whilst Móði crater appears as a perfect volcanic cone against the ice cap backdrop. Steam still rises from these formations on cold days, particularly noticeable during winter months.

The area presents unique photographic opportunities, with the contrast between black lava, white ice, and often dramatic cloud formations creating an otherworldly atmosphere. The trail here follows marked paths to prevent damage to the fragile new ecosystem beginning to establish itself on the cooling lava.

Descent to Þórsmörk

The final 9 kilometres descend 800 metres through increasingly green terrain as the trail drops into the sheltered Þórsmörk valley. This section requires careful navigation, particularly in poor weather, as the path switches between rocky terrain and loose scree slopes. The reward comes in panoramic views of the valley's birch forests and the surrounding glacial peaks of Katla, Tindfjallajökull, and Eyjafjallajökull.

Practical Considerations

Accommodation and Logistics

The Baldvinsskáli hut, operated by Útivista, sits at the halfway point and provides essential shelter for overnight hikers. Accommodation costs 9,500 ISK for a bed in shared dormitories, with sleeping bag rental available for 2,500 ISK. The hut features basic cooking facilities, though all supplies must be carried in.

Many hikers combine Fimmvörðuháls with the Laugavegur trail, creating a 4-6 day highland adventure. The Volcano Huts company operates buses from Þórsmörk to Landmannalaugar for 8,900 ISK, allowing seamless connection between the two famous routes.

Weather and Timing

The hiking season runs from mid-June through mid-September, with July and August offering the most stable conditions. However, the high-altitude sections can experience snow and sub-zero temperatures even in midsummer. Wind speeds regularly exceed 80 km/h on the exposed plateau sections, making waterproof and windproof gear essential.

Weather conditions between the coast and highlands can differ dramatically. Skógar might experience calm, mild weather whilst the pass suffers from storms and near-zero visibility. Check the Icelandic Met Office forecast specifically for mountain areas before departure.

Safety and Equipment

The trail crosses several unbridged streams that can become impassable during heavy rainfall or glacial melt. The Krossá River near Þórsmörk presents particular challenges, with water levels fluctuating throughout the day based on glacial melt rates.

Essential equipment includes navigation tools (GPS recommended), emergency shelter, extra food supplies, and clothing suitable for winter conditions regardless of season. Mobile phone coverage exists at both ends but disappears entirely in the middle sections.

Beyond the Beaten Path

Experienced hikers can extend the route by exploring side trails to Mýrdalsjökull glacier tongue or ascending the crater rims for expanded views. These diversions require advanced glacier travel skills and proper equipment, including crampons and rope systems.

The Fimmvörðuháls Pass represents more than just a hiking trail—it's a journey through Iceland's geological story, from ancient basalt formations to volcanic features created within recent memory. For those seeking to understand the dynamic forces that continue shaping this remarkable island, few experiences match walking between these ice caps whilst surrounded by evidence of the Earth's raw creative power.
