Is Hiking in Iceland Dangerous? Real Risks and Safety Tips
Is hiking in Iceland dangerous? For prepared hikers on marked trails in summer, the risk is generally low. But Iceland's hazards are different from many other countries: rapidly changing weather, glacial rivers, crevassed ice, crumbling sea cliffs and boiling geothermal ground. Most accidents involve people who underestimated one of these. This guide explains the real risks and the practical Iceland hiking safety tips that keep you out of trouble.
Weather: the number one risk
Iceland's weather can change from calm sunshine to gale-force wind, rain or snow within hours, and the highlands can see snow in any month. Wind is often the real danger: strong gusts make walking on ridges hazardous and drive cold rain through inadequate clothing, leading to hypothermia even in summer. Check the forecast on vedur.is before every hike, paying attention to wind speed and gusts, not just temperature. Carry full waterproofs and warm layers, and set a turnaround rule before you start. Waiting a day is always better than pushing on.
Rivers and river crossings
Many Icelandic rivers are fed by glaciers. They are cold, fast, opaque with silt and can rise significantly on warm afternoons or after rain. Unbridged crossings on routes like the Laugavegur are usually manageable in summer, but they demand respect. Cross early in the day, unbuckle your hip belt, face upstream and use poles. Never attempt a crossing that looks too deep or fast; wait or turn back. Drivers should be equally cautious, as river fords on highland roads have swept away vehicles. Our river crossing guide covers technique in detail.
Glaciers
Glaciers look solid but hide crevasses, moulins and thin snow bridges. Glacier tongues close to roads and car parks, such as Sólheimajökull, attract visitors who wander onto the ice in trainers, which is extremely dangerous. Calving fronts and meltwater lagoons add further risks. The rule is simple: only go on a glacier with a certified guide and proper equipment. Admire glaciers from a safe distance otherwise, and keep well back from glacier fronts and lagoon shores.
Cliffs, sea stacks and sneaker waves
Many viewpoints have no fences. Cliff edges in Iceland are often undercut, loose or covered in slippery moss, and strong gusts can unbalance you near an edge. Stay well back from the edge on canyon rims such as Múlagljúfur and Stuðlagil, and on coastal cliffs. On black sand beaches like Reynisfjara near Vík, sneaker waves can surge far up the beach without warning and drag people into the sea. Never turn your back on the ocean and obey the warning lights and signs.
Geothermal areas
In places like Landmannalaugar, Kerlingarfjöll, Reykjadalur and Hverir, the ground can be a thin crust over boiling water or mud. Stepping off the trail can cause severe burns. Water in hot springs and vents can be scalding, and some pools are far hotter than they look. Stay on marked paths and boardwalks, keep children close and only bathe in designated bathing spots. Test water carefully with your hand before getting in, and never enter a pool or stream that is not clearly a bathing area.
Iceland hiking safety tips
The habits that prevent the vast majority of incidents: None of these is complicated, and together they address the situations behind most callouts for Iceland's search and rescue teams. Make them a routine before every outing, whether it is a short waterfall walk or a multi-day trek through the highlands, and adjust your plans the moment conditions start to change for the worse.
- Check vedur.is for weather, umferdin.is for roads and SafeTravel.is for alerts before you go.
- Leave a travel plan on SafeTravel.is for longer or remote hikes.
- Install the 112 Iceland app and keep your phone charged with a power bank.
- Carry waterproofs, warm layers, food, water, a map and a headlamp.
- Stay on marked trails and respect closures.
- Set turnaround times and wind limits before you start.
- Tell someone your route and expected return time.
- Never walk on glaciers without a certified guide.
What to do in an emergency
Call 112, the single emergency number for police, ambulance, fire and search and rescue. The 112 Iceland app can send your location to emergency services with one tap, even with a weak signal, and lets you check in during your hike. Coverage is good in many areas but patchy in deep valleys and remote regions. Iceland's search and rescue teams, organised under ICE-SAR (Slysavarnafélagið Landsbjörg), are largely volunteer-run and highly experienced. If you get lost in fog, stop, stay together, put on warm layers and call for help rather than wandering further.

Frequently asked questions
Is hiking in Iceland safe for beginners?+
Yes, on easy marked trails in summer with proper clothing and a weather check. Beginners should avoid remote routes, glaciers without a guide and long highland treks without experience or a guide.
What is the emergency number in Iceland?+
112. It covers police, ambulance, fire and search and rescue. The 112 Iceland app can also send your GPS location to emergency services.
What is a SafeTravel travel plan?+
A travel plan is a free itinerary you can leave on SafeTravel.is describing your route and timing, so search and rescue have useful information if something goes wrong.
Are there dangerous animals in Iceland?+
No. Iceland has no snakes or large predators. The rare exception is polar bears, which very occasionally drift ashore in the far north and Westfjords. Arctic terns may dive at you near nesting sites in summer.
Why do people die hiking in Iceland?+
Most serious incidents involve weather exposure, falls from cliffs or steep ground, glacier accidents without a guide, river crossings and sneaker waves on beaches, often when warnings were ignored.
