Backpacking in Fimmvörðuháls
🌟 Highlighthike ranked #2
By Johan Kruseman 🇳🇱 | Updated September 23, 2026

Most people think Fimmvörðuháls is just a “waterfall walk” you tack onto a South Coast road trip. It isn’t. It’s a full-body, all-day mountain crossing that will chew up anyone who treats it like a casual stroll.

Fimmvörðuháls sits between Skógar and Þórsmörk in South Iceland, threading the gap between Eyjafjallajökull and Mýrdalsjökull. The trail runs roughly 22-26 km depending on your route, and you feel almost every meter: endless stairs past roaring waterfalls, a long grind onto a windy plateau, then ash, lava, and snowfields where the 2010 eruption left still-warm-looking craters. The payoff is huge—waterfall canyon, Martian lava, then that first beer or soup in Þórsmörk with your legs humming. It’s tougher than most day hikes on the Laugavegur and more dramatic than the easy loops around Skógar, but also more committing. Public buses make the trailheads reachable, yet weather, river crossings, and the sheer distance mean this is not a “see how it goes” hike.

💡 HighlightsDon't-miss highlights and experiences

  1. Skógafoss and the waterfall chain — The hike kicks off under one of Iceland’s most dramatic single-drop waterfalls; the roar, constant spray and often-present rainbows make for an instant “I’m in Iceland” moment. There’s also a stair path up the side that gives you a different perspective of the valley and the smaller cascades that tumble down from the highlands.
  2. The 2010 lava field and Magni & Móði craters — You literally walk through fresh volcanic terrain created during the Eyjafjallajökull eruption: sharp lava, black glassy flows, and two raw little craters named after Thor’s sons. It feels otherworldly — my personal favorite on the trail, because few hikes let you inspect brand-new geology and still smell that scorched-earth vibe.
  3. The high pass with glacier panoramas — Near the summit

It feels otherworldly — my personal favorite on the trail, because few hikes let you inspect brand-new geology and still smell that scorched-earth vibe.
  3. The high pass with glacier panoramas — Near the summit the trail opens up to wide views of the ice caps (Eyjafjallajökull and Mýrdalsjökull) and long lowlands below, a dramatic contrast of black sand, snow and green valleys. On a clear day the scale is jaw-dropping — you can see how the glaciers dominate the landscape in a way most lowland hikes never do.
  4. Þórsmörk valley — the lush oasis — After the barren high pass, descending into Þórsmörk feels like arriving somewhere protected: birch woods, moss carpets, and sheltered river channels. The contrast between the windswept highland and this microclimate makes the end of the route uniquely satisfying for camping or a long, lazy lunch.
  5. Glacial rivers, braided fords and narrow canyons — The trail forces you to cross braided glacial streams and squeeze through rocky defiles, which adds a real sense of adventure and keeps the terrain varied. These water crossings and the small canyon sections give the hike a proper backcountry feel — bring waterproof boots or be ready to ford.

🌤️ When to go?Weather, crowds, and seasonal trade-offs

  • Weather: The trail is a raw beast outside summer. Snow and ice dominate from October to May, turning the path into a slippery, dangerous slog. June through early September offers the most stable weather, though sudden shifts are the norm—pack for wind, rain, and sun in one day.
  • Temperature: Summer highs hover around 10-15°C (50-59°F), but nights can dip near freezing. Early or late season hikes risk subzero chills that bite through layers, so timing your trek when temperatures stay above 5°C (41°F) during the day is safer and more comfortable.
  • Daylight Hours: Iceland’s midnight sun floods the trail with light from late May to mid-July, stretching your hiking window to nearly 24 hours. Outside this window, days shrink fast—by September, expect 10-12 hours of daylight, enough but demanding

  • Daylight Hours: Iceland’s midnight sun floods the trail with light from late May to mid-July, stretching your hiking window to nearly 24 hours. Outside this window, days shrink fast—by September, expect 10-12 hours of daylight, enough but demanding an early start and efficient pace.
  • Crowds: July and August bring the busiest foot traffic, especially on weekends. The trail can feel like a conveyor belt of hikers. For a quieter, more solitary grind, aim for June or early September when the crowds thin but conditions remain manageable.
  • Seasonal Activities: Summer opens up glacier walks and volcanic landscapes along the route, adding layers to your adventure. Outside summer, these are off-limits or require specialized gear and guides, pushing the trip into a serious expedition rather than a backpacking trek.
  • Price Fluctuations: Accommodation and transport costs spike in July and August. Booking early is essential. June and September offer better deals and availability, letting you stretch your budget without sacrificing the experience.
Pro-tip: Start your hike in early June or early September to dodge the crowds, catch decent weather, and enjoy longer daylight without the summer price surge—this sweet spot balances grit and reward perfectly.
