Siglufjörður Mountain Hiking: The North's Hidden Trails

Beyond Siglufjörður's celebrated herring heritage lies a mountainous wilderness that rivals Iceland's most famous highland routes. This former fishing capital, perched dramatically on the Tröllaskagi Peninsula's northern edge, serves as the gateway to some of North Iceland's most rewarding yet overlooked hiking terrain. Where most visitors see a charming historical town, experienced hikers discover a basecamp for extraordinary alpine adventures.

The Tröllaskagi Peninsula Terrain

Siglufjörður sits within the Tröllaskagi Peninsula, a geological masterpiece shaped by volcanic activity and glacial carving over millions of years. The surrounding peaks, reaching heights of 1,400 metres, create a natural amphitheatre of steep-sided valleys, knife-edge ridges, and hidden cirques that harbour snow well into summer.

The mountains here consist primarily of Tertiary basalt flows, creating the characteristic stepped cliff faces and stable hiking surfaces that define North Iceland's landscape. This geological foundation, combined with the area's maritime climate, produces hiking conditions distinct from the volcanic desert trails of the interior highlands.

Essential Mountain Routes

Hestkjallur Ridge (1,167m)

The crown jewel of Siglufjörður hiking, Hestkjallur offers a challenging 14-kilometre round-trip ascent that rewards with panoramic views across three fjords. The trailhead begins 3 kilometres south of town centre via Route 76, where a small car park marks the start of this demanding day hike.

The initial 4 kilometres follow a well-marked path through birch scrubland before transitioning to exposed alpine terrain. The final 3-kilometre push to the summit requires scrambling across loose scree and snow patches that persist until July. Allow 7-8 hours for the complete circuit, with the steepest sections occurring in the final kilometre where the trail gains 400 metres in elevation.

Weather conditions change rapidly above 800 metres, making proper gear essential. The summit provides commanding views of Siglufjörður, Ólafsfjörður, and on clear days, the distant peaks of Vatnajökull National Park.

Kaldbakur Peak Circuit

This moderate 11-kilometre loop connects multiple peaks along the fjord's eastern rim. Starting from the Siglufjörður Museum car park, the trail initially follows the old sheep paths used by farmers for centuries. Archaeological evidence suggests these routes date to the Settlement Era, when Norse farmers first established seasonal grazing grounds in these highlands.

The circuit's highest point, at 1,089 metres, offers dramatic perspectives of the Greenland Sea stretching toward the Arctic Circle. The descent via Strákar Pass requires careful navigation through a boulder field created by freeze-thaw cycles during the last glacial maximum.

Múlagljúfur Canyon Trail

A hidden gem accessible only to those willing to venture 8 kilometres inland, Múlagljúfur represents one of North Iceland's most spectacular yet unknown gorges. The 6-kilometre trail to the canyon rim follows an unmarked route that requires GPS navigation and experienced mountain skills.

The canyon itself, carved by glacial meltwater during the Holocene period, drops 200 metres into a narrow chasm where Arctic foxes den during winter months. The trail continues beyond the main viewpoint to a series of waterfalls that flow year-round despite their elevation of 950 metres above sea level.

Practical Considerations

Access and Transport

Siglufjörður lies 76 kilometres from Akureyri via Route 82, a mountain road that crosses Öxnadalsheiði Pass. During winter months (October-April), this route requires winter tyres and can close during severe weather. The Héðinsfjarðargöng tunnel, opened in 2010, provides reliable year-round access at a toll cost of 1,500 ISK per vehicle.

Limited bus service operates from Akureyri during summer months (June-August) through SBA-Norðurleið, with tickets costing 3,200 ISK each way. Most serious hikers opt for rental vehicles to access remote trailheads.

Accommodation and Supplies

Sigló Hotel (rates from 28,000 ISK per night) serves as the town's premier base, whilst Hvanneyri Guesthouse offers budget accommodation from 12,000 ISK. Both provide secure gear storage and detailed local trail information.

The Samkaup Strax supermarket stocks essential hiking supplies, though specialised gear requires advance purchase in Reykjavik or Akureyri. Petrol stations operate limited hours, making fuel planning crucial for day trips to remote trailheads.

Weather and Timing

The hiking season extends from June through September, with optimal conditions occurring during July and August when daylight extends past 22:00. However, the shoulder months offer advantages: fewer tourists, better photography light, and the possibility of Northern Lights sightings during September evenings.

Mountain weather differs significantly from coastal conditions. Temperatures can drop 15°C between sea level and peak elevations, whilst wind speeds often double above 1,000 metres. The Iceland Met Office provides detailed mountain forecasts essential for route planning.

Safety Protocols

These trails demand respect and preparation. Mobile coverage disappears beyond 5 kilometres from town, making GPS devices and emergency beacons advisable for solo hikers. The Icelandic Association for Search and Rescue (ICE-SAR) recommends registering hiking plans at safetravel.is, particularly for multi-day expeditions.

River crossings present seasonal hazards, especially during spring melt (May-June) when snowmelt swells normally fordable streams. Several routes require technical scrambling skills and appropriate footwear for loose volcanic rock.

The Authentic North Iceland Experience

Siglufjörður's mountain trails offer something increasingly rare in Iceland: solitude combined with spectacular scenery. Where the Ring Road's famous hikes attract hundreds daily, these northern routes might see a dozen hikers per week during peak season.

This remoteness comes with responsibility. Trail maintenance relies on volunteer efforts from local hiking clubs, and the fragile alpine vegetation requires careful foot placement to prevent erosion. The reward for this conscientiousness is access to hiking experiences that capture Iceland's wilderness character as it existed decades ago.

For those seeking genuine adventure beyond Iceland's well-trodden paths, Siglufjörður's mountains deliver an authentic encounter with the island's most dramatic and pristine landscape. The trails may be hidden, but for prepared hikers, they reveal the very essence of North Iceland's untamed beauty.
