Hiking Safety
Stay safe on the trails.
Always tell someone your hiking plans and expected return time. Carry emergency communication device in remote areas.
Check weather conditions before setting out. Turn back if conditions deteriorate. Never underestimate mountains.
Stay on marked trails. Getting lost in unfamiliar terrain can be dangerous. Carry navigation tools.
Be aware of wildlife. Research local animals and know how to respond to encounters.
Start early to allow plenty of daylight. Always aim to be back before dark.
Local Hazards
- River crossings – many highland trails require unbridged river crossings that can be dangerous in high water; always cross at the widest, shallowest point facing upstream
- Rapidly changing weather – temperature can drop 15°C and wind increase to storm force within hours; always carry full waterproofs, hat, and gloves even in sunshine
- Unmarked F-roads – highland F-roads (prefix F) are only for 4WD vehicles; driving a 2WD on them voids rental insurance and risks getting stranded
- Glaciers – never walk on glaciers without a certified guide; crevasses are often hidden under snow bridges and can swallow a person
- Sneaker waves at black sand beaches – unpredictable large waves at Reynisfjara have killed visitors; stay well back from the waterline
- Geothermal areas – boiling mud pots and fumaroles can reach 100°C; stay on marked paths at Geysir, Námafjall, and Krafla
- Sunburn and snow blindness – Iceland's clean atmosphere at high altitude intensifies UV radiation; use SPF 50 and polarized sunglasses on glaciers
- GPS reliance – mobile signal is absent in the highlands; download offline maps and carry a physical map or compass
