Iceland is breathtaking, but its nature does not forgive carelessness. The weather can change in minutes, the roads are demanding, and many visitors underestimate the conditions. With the right preparation you can travel safely all year round. Remember one number above all: the emergency line is 112, which reaches police, ambulance and rescue teams alike.
Weather – always check first
Icelandic weather is famously unpredictable and can swing from sunshine to storm in a single day. Before you set off, always check vedur.is for the forecast and warnings, and safetravel.is for road and hiking conditions.
- The wind can be so strong it rips a car door out of your hands – always hold the door firmly when you open the car, or it may be bent or torn off entirely.
- Orange and red warnings mean genuine danger. Postpone your plans while they are in effect and trust local advice.
- Dress in layers: a wool base layer, a warm mid-layer, and a windproof, waterproof shell. A hat, gloves and solid hiking boots make a real difference.
- Rain and sleet driven by horizontal wind chill the body fast; do not underestimate the risk of hypothermia, even in summer.
Driving – respect the roads
A rental car gives you the most freedom, but driving in Iceland demands attention. Many roads are gravel, blind rises are common, and conditions change quickly.
- F-roads in the Highlands require a 4x4. Ordinary cars are not allowed on them and insurance will not cover damage.
- The Highlands have unbridged river crossings. Judge depth and current before you drive across, go slowly and never alone; if you are in doubt, turn back.
- Many bridges are single-lane. The vehicle closest yields or waits; take your time and watch for oncoming traffic.
- Gravel and loose stones call for lower speeds, especially in bends and near the shoulder where the car can slide.
- Off-road driving is illegal and scars fragile nature that takes decades to recover. Fines are heavy and strictly enforced.
- Keep your headlights on at all times – it is the law, day and night – and wear seatbelts in every seat.
Reynisfjara and the sea
The black sand beach of Reynisfjara is stunning but dangerous. It is known for sneaker waves that surge far up the sand without warning and can drag people into the cold sea. Fatal accidents have happened here. Keep well back from the water, never turn your back on the waves, and watch the on-site warning-light system.
Hiking
Iceland's wilderness is superb for walking, but preparation is everything, and conditions can deteriorate quickly on the mountains.
- Leave a travel plan on safetravel.is before you head out, so rescue teams know where you are.
- Download the 112 Iceland app – it can send your location to rescue teams with a single tap.
- Carry food, water, warm clothing, a compass or GPS, and a fully charged phone.
- Turn back if the weather worsens – the mountain will still be there the next day.
- Mobile coverage can be patchy in the Highlands; do not rely on your phone alone.
Winter, ice and darkness
In winter daylight is short – as little as four to five hours in December. Roads become icy and slippery, with hidden patches of ice in shaded spots. Drive slowly, use studded tyres, and plan your journeys so you reach your destination before dark. If you get stuck, stay in the car and call 112.
Geothermal areas, glaciers and gas
- In geothermal areas such as Geysir and Hverir, stay on the marked paths – the ground can be thin and the water is boiling just below the surface.
- Never go onto glaciers without an experienced guide and proper equipment; crevasses are hidden under the snow.
- Near eruptions and hot springs, dangerous gas can build up; respect closures and follow official instructions.
- In sandstorms and ash storms visibility can vanish in an instant; wait it out in a safe place.
Insurance and preparation
Carry good travel insurance that covers rescue and medical care. Keep emergency numbers, your accommodation location and your plan easily accessible. With common sense, the right gear and respect for nature, your trip to Iceland will be both safe and unforgettable.
