Planning an Iceland trip and don't know where to start?
Six questions, in the order they matter: when, how long, who with, budget, car or tours, where to sleep. We point you to the answer for each one.
Hiking in Iceland: safety, season, and which hike to choose
Hiking in Iceland
How to stay safe, how to pick a walk you will actually enjoy, and when to turn around
Everyone online says the hiking here is dangerous. Am I out of my depth?
Probably not. Most visitors who get into trouble were not on a hard trail, they were on an easy one in bad weather, dressed for a city. If you check the forecast the morning of, wear a windproof shell, and are willing to turn back, ordinary fitness is enough for a great day out here.
The two genuine no-go zones for unguided visitors are glaciers and the highlands outside summer. Everything else is a matter of weather and honesty about your own pace.
Iceland does not have a big network of gentle, waymarked woodland paths. It has open terrain, very little shelter, and weather that changes faster than your plans do. That sounds intimidating written down, and it is why the forums frighten people. In practice, thousands of ordinary visitors walk here every week and go home fine.
What separates a lovely day from a frightening one is almost never fitness. It is wind, visibility, footwear, and whether you were willing to stop.
Before you set off: five minutes that matter more than the gear
- Check the forecast the morning of, not the night before. Use vedur.is and read the wind number, not just the icon. See how to read an Icelandic forecast.
- Check trail and road conditions. safetravel.is carries alerts for closed or hazardous routes. If the access road matters, check road status too.
- Tell someone your plan. Route, start time, expected return. Either a person who will notice, or a travel plan submitted on safetravel.is.
- Install the 112 Iceland app. Free, works on a weak signal, and sends your GPS position to search and rescue with one press.
- Charge your phone and bring a battery bank. Cold flattens batteries quickly, and your phone is your map, your torch, and your emergency call.
Wind is the difficulty rating here
A trail described as easy in a guidebook can be genuinely dangerous at 20 metres per second. There is rarely a tree or a wall to hide behind, and exposed ridges funnel the wind rather than shelter you.
- Under 10 m/s: comfortable. Normal walking day.
- 10 to 15 m/s: tiring and loud. Fine on low ground, unpleasant on exposed ridges.
- 15 to 20 m/s: hard work. Avoid cliff edges, ridges, and anywhere with loose footing.
- Over 20 m/s: do not go up. This is the range where people are knocked over and car doors are torn off.
Rain matters less than people expect. Fog matters more. Icelandic trails are often marked by cairns or posts spaced far apart, and in thick fog you can lose the line between them in minutes.
Field note
What to wear and carry
Three layers, no cotton anywhere. That is most of it.
- Base: wool or synthetic. Cotton holds sweat and then chills you.
- Mid: fleece or light down.
- Shell: waterproof and genuinely windproof, with a hood that tightens around your face. A hood that blows off is the single most common gear failure here.
- Boots: waterproof, ankle support, real grip. Trainers on wet lava is how ankles get hurt.
- Always: hat, gloves, water, food, headlamp outside midsummer, and a paper or offline map.
- Autumn to spring: micro spikes that slip over your boots. Icelandic paths ice over early and locals wear them without embarrassment.

When to turn back, decided in advance
Turning back feels like failure in the moment, which is exactly why you decide the rules before you start, while you are still calm and warm.
- Visibility drops and you cannot see the next marker.
- Wind is strong enough that you are bracing rather than walking.
- You are wet through on any layer other than the shell.
- Someone in the group is quiet, slow, and cold. That is early hypothermia, not a bad mood.
- You have reached your turnaround time. Set one before you start, based on darkness and how long the way down takes, and honour it even if the summit is close.
The money and time you have already spent getting to the trailhead is gone either way. It should not buy you an extra hour of risk.
Which hike actually suits you
Be honest about four things and the choice makes itself.
- Do you have a car? Without one, you are choosing between Reykjavík area walks and bus served trailheads.
- How much daylight is there? In November you have about five usable hours. In June you have all of them. Check the daylight calendar.
- What is the season? Highland routes are a summer thing. Everything else shifts from walk to ice walk.
- What is your group's slowest pace? Plan for that person, not for you. Add a third to any time estimate you read online.
Hikes that are worth a visitor's day
Not a ranking, and deliberately short. These are the ones that are realistic to reach, reliably rewarding, and hard to get badly wrong in decent weather. Always check current conditions before you go, since trails close and access roads change.
Reykjadalur hot river, Hveragerði
About 3 hours return, steady uphill, 45 minutes from Reykjavík
The famous one, and it earns it: you walk up a steaming valley and sit in a warm river at the top. Muddy and slippery in wet weather, and genuinely cold changing out of the water in wind. Bring a towel, a warm hat for after, and expect company.
Mount Esja, Þverfellshorn
2 to 4 hours return, reachable by city bus, 25 minutes from town
Reykjavík's local mountain and the easiest real hike to do without a car. Numbered stones mark your progress, so you can stop wherever you like without feeling you failed. The final scramble to the summit rock is chained and often icy. Stopping at Steinn, the big stone, is a perfectly good day.
Svartifoss and Skaftafell, Vatnajökull National Park
1.5 hours return for the waterfall, longer loops available
The most forgiving proper hiking area in the country: a visitor centre, toilets, rangers, well marked trails, and options from an hour to a full day. Ideal if you want to test yourself before committing to anything bigger. Parking is paid.
Glymur waterfall, Hvalfjörður
3 to 4 hours return, 1 hour from Reykjavík, summer only
Dramatic and steep, with a log and wire river crossing that is removed outside summer. There are exposed sections with real drops. Wonderful if you are steady on your feet, a bad idea if heights or loose ground worry you, and not one to do in rain.
Fimmvörðuháls, Skógar to Þórsmörk
8 to 12 hours, roughly 25 km, late June to early September
A serious full day between two glaciers, past the 2010 eruption site. Snowfields linger at the pass into July and the weather at the top bears no relation to the weather at the car park. Only attempt with an early start, a good forecast, and a plan for getting back from Þórsmörk.
Laugavegur, Landmannalaugar to Þórsmörk
2 to 4 days, roughly 55 km, late June to early September
The classic multi-day route. Huts must be booked many months ahead, unbridged river crossings are part of the trail, and access is by highland bus or a proper 4x4. This is not a first hike in Iceland, but it is the reason a lot of people come back.
Elliðaárdalur and the coastal path, Reykjavík
1 to 2 hours, flat, no car needed, any season
Not spectacular, and that is the point. When the weather closes in or the group is tired, a green river valley or the seafront path still gives you air, movement, and something to look at. This is the honest answer on a bad day, not a consolation prize.
Glaciers, ice caves, and where a guide is not optional
Do not walk onto a glacier without a guide and equipment. Crevasses are covered by thin snow bridges you cannot see, and the edges of glacier tongues collapse without warning. This is the one place where the calm answer is simply no.
The same applies to ice caves, which are only safe with a guide in winter, and to icebergs at Jökulsárlón and Diamond Beach. People are swept out by rogue waves on that coastline, most notoriously at Reynisfjara, where the waves arrive far up a beach that looks harmless.
Guided glacier walks are widely available from Skaftafell and Sólheimajökull and do not require previous experience.
Trail etiquette that locals notice
- Stay on the path. Moss takes decades to recover from a single footprint and off-trail damage is what makes residents resent visitors.
- No drones in national parks without permission, and not near nesting birds.
- Close every gate behind you. Sheep are someone's livelihood.
- Take everything out with you, including tissue. Many trailheads have no bins.
- Do not build new cairns. They confuse navigation for the next person in fog.
- Hours at visitor centres, cafés, and toilets drift from what Google says. If your day depends on it, find the phone number and call ahead.
If something goes wrong
Call 112. Search and rescue in Iceland is a volunteer service and they would far rather come out early than late. Nobody will make you feel foolish for calling.
If you are lost or hurt: stop moving, get out of the wind, put on every layer you have, and use the 112 app to send your position. Walking on in fog to find the path is how a manageable situation becomes a search.

Common questions
Do you need a guide to hike in Iceland?
For marked day hikes near Reykjavík and along the south coast, no. For glaciers, ice caves, and anything on or near a glacier tongue, yes, always. Crevasses are not visible from the surface and people die on them every few years. For multi-day highland routes, a guide is optional if you are experienced with river crossings and navigation in poor visibility, and strongly recommended if you are not.
When is hiking season in Iceland?
Lowland and coastal trails are walkable most of the year, with ice and short daylight in winter. Highland routes such as Laugavegur and Fimmvörðuháls are generally passable from late June to early or mid September, depending on snow. Outside that window, mountain huts close, buses stop running, and snowfields hide the trail markers.
Is it safe to hike alone in Iceland?
On busy marked trails in good weather, yes. The risk is not people, it is weather and terrain. If you hike alone, tell someone your route and expected return time, or submit a travel plan at safetravel.is. Do not rely on phone signal in valleys and highland areas.
What should I wear hiking in Iceland?
Wool or synthetic base layer, a warm mid layer, and a genuinely windproof and waterproof shell with a hood that tightens. No cotton. Waterproof boots with ankle support and grip. Hat and gloves in every season. Wind, not temperature, is what makes people turn back.
Can you drink the water from streams while hiking in Iceland?
Running water from streams in uninhabited areas is generally clean and safe. Avoid water downstream of sheep pasture, huts, or campsites, and avoid glacial rivers, which are full of grey silt. Tap water everywhere in the country is safe, so filling bottles before you set off is the simplest option.
Do I need to pay to hike in Iceland?
The trails themselves are free. What you often pay for is parking, typically 750 to 1,000 ISK at popular sites, and mountain huts on multi-day routes, which must be booked months in advance.
What is the emergency number for hikers in Iceland?
112 for all emergencies. Download the free 112 Iceland app before you set off: it can send your GPS position to search and rescue with one button, and it has a check in feature that logs where you are.
Sources we check: the Icelandic Met Office (vedur.is) for wind and warnings, safetravel.is for alerts and travel plans, and the Icelandic Road Administration (road.is) for access roads. Conditions change, so treat everything here as preparation, not a live report.
The three checks, in this order
- 1. vedur.is for the weather and any warnings.
- 2. road.is for road status and closures.
- 3. Can I drive today? which reads both feeds for your exact spot and answers in one line: Go, Caution, or Not today.
