Start at first light
Begin early to avoid afternoon winds and give yourself margin for river crossings and slow sections.
Between Fire and Ice: Hiking Fimmvörðuháls, Iceland’s Volcanic High Route
A high volcanic pass between glaciers — where fresh lava meets ancient ice
Reykjavik, Southern Region•By Robert Eric Crews•Land Adventures,Camping Overnight,Wildlife Nature•July•summer
Continue ReadingYou round the last bend below Skógafoss and the roar of water gives way to wind, gravel, and a horizon of black and white. On one side, a jagged glacier clings to a dome of ice; on the other, a raw line of lava fields and fresh rock — the dramatic geography that marks Fimmvörðuháls. The trail forces you to trade the soft, birch-fringed lowlands for a lunar slope where every step pitches you between two great forces: the cold, shuffling ice of Mýrdalsjökull and the hot, recent scars of volcanic fire.
Duration8–12 hours (one-way long day) or 1–2 days with overnight
Trail Wisdom
Trail Wisdom
Carry microspikes in shoulder seasons
Snow patches persist into summer; microspikes or light crampons make ascents and descents safer.
Filter water from streams
Streams are plentiful but treatable — carry a filter or purification tablets for safety.
Use trekking poles
Poles stabilize you on scree and reduce knee strain on long descents into Þórsmörk.

Hidden Gems
- A viewpoint just above the 2010 crater field that offers unobstructed views of Magni and Móði
- The moss-carpeted river terraces descending into Þórsmörk that feel like a different ecosystem
Wildlife
Arctic fox (rare sightings), Ptarmigan and migratory waders in summer
Conservation Note
Stick to marked trails to protect fragile moss and lichen that take decades to regrow; local land managers limit camping to designated sites to reduce erosion.
Fimmvörðuháls has long served as a high route between valleys in southern Iceland; the 2010 fissure eruption created new craters that altered the ridge.
Seasonal Guide
Seasonal Guide
spring
Best for:watching winter melt patterns, fewer crowds
Challenges:persistent snow and icy patches, cold, unpredictable weather
Late spring (May–early June) can still hold deep snow and swollen rivers; only attempt with winter gear or a guide.
summer
Best for:classic hiking conditions, long daylight and wildflowers
Challenges:crowds on peak days, occasional late-season snow
Mid-June through August is the most reliable window for clear trails, hut access and shuttle services.
fall
Best for:lonely trails, dramatic light and lower insect activity
Challenges:shortening days, early snowstorms
September offers crisp air and color but prepare for wind and the possibility of early winter conditions.
winter
Best for:experienced mountaineers seeking solitude, aurora views if conditions permit
Challenges:deep snow, avalanche risk, river ice, need for advanced glacier and winter skills
Winter should only be attempted with full alpine gear and local guide support; many access roads are closed.
Photographer's Notes
Photographer's Notes
Shoot the ridge at golden hour for saturated colors; use a wide-angle to capture glacier-to-lava juxtapositions and a neutral-density filter for silky water at Skógafoss. For crater details, zoom lenses reveal textures; keep lens cloths handy for volcanic dust.
What to Bring
What to Bring
Waterproof hiking boots
EssentialSturdy, waterproof boots protect against scree and stream crossings while supporting ankles on uneven terrain.
Microspikes or light crampons
EssentialUseful for lingering snow patches and icy sections early and late in the season.
Lightweight tent or hut reservation
Overnighting lets you split the route and catch sunrise on the ridge; huts require advance booking.
Trekking poles
EssentialPoles improve balance on scree and reduce strain during sustained ascents and descents.

Did You Know
In March 2010 fissure eruptions on Fimmvörðuháls produced two new craters named Magni and Móði; this eruption preceded the larger Eyjafjallajökull eruption that disrupted European air travel.
