Our take on this one

Eleven kilometres over Grímannsfell above Mosfellsbær, half an hour from Reykjavík, with 450 metres of climbing and admission to the Halldór Laxness museum included — the literary half is not decoration, this is the country the Nobel laureate wrote about and lived in. The trail is largely unmarked and crosses bogs and ditches before the steep pull to the top, so it asks for agility more than lungs. Ten o'clock start, back by 15:30, maximum fifteen people, certified mountain leader, and you bring lunch, water, waterproofs and boots. Age 16 and over. Hikers of Iceland run one tour a day, so check their other dates if this one shows nothing.

Book it if: Walkers who want a longer, wilder route than the tourist paths and like the Laxness connection at the end.
Skip it if: Unmarked, boggy ground for eleven kilometres — if you want a clear path and a view without the navigation, take the Móskarðshnjúkar day.

This wild, often unmarked trail is perfect for true adventurers, offering a raw and unspoiled experience of Iceland’s breathtaking landscapes. Along the way, we’ll traverse a diverse terrain of lush fields, soft bogs, and rugged ditches that demand agility and a spirit of exploration. As we ascend, a steep and exhilarating slope awaits, pushing us to new heights—both physically and mentally. But the reward? A summit that unveils some of Iceland’s most spectacular views, surrounded by lovely wilderness.

Stunning Views and Hidden Gems

Reaching the peak of Stórhóll, we’ll be greeted by sweeping panoramic vistas stretching over Iceland’s rugged terrain, a sight that few get to witness up close.

His former home, now a museum, offers a fascinating look into the life and creative mind of one of Iceland’s most celebrated literary figures. As you explore the house and stroll through the beautiful garden where Laxness found inspiration, you’ll gain a deeper appreciation for the country’s rich literary heritage and its deep connection to the dramatic landscapes surrounding us.

If the weather cancels this tour

Iceland's weather is real. What usually stops this one is wind above the treeline and river levels after rain — the guide decides on the day. Here is exactly what happens to your booking.

1Hikers of Iceland decides, and tells us. Operators cancel when it is unsafe or pointless, and we back that call every time — we do not ask them to run anyway.
2We contact you by email, and by phone if your tour is the same or next day. You choose: another date if there is one you can make, or a full refund. There is no fee and nothing to argue.
3The refund goes back to the card you paid with, through Stripe, usually visible within a few working days. If this tour was one of several in your booking, the others are untouched.

What you do not get is the day back. If this is the only free day in your plan, put a spare day next to it — the planner leaves days free with the rest-day option. And if you want out because the forecast looks bad, that is your own cancellation: free until 1 day before departure, the operator's policy after that.

Why this one and not the cheaper one?

The nearest cheaper Queer History Walk | Reykjavík Pride 2027 from Pink Iceland is €73 — €22 less. Here is every difference we can actually measure.

	Hikers of Iceland · €95	Pink Iceland · €73
How long it runs	5.5 hours	3 hours
Changing your mind	Free until 24 h before	Free until 72 h before
How hard it is	Moderate	Easy

The €22 buys you 2.5 more hours out. Whether that is worth it is your call — but that is what the difference is.

Who this is not for

Not for families with children under 16 — the operator will not take them, even with a parent.

Must see and do! I am not an avid hiker or adventurer and this kickstarted a whole new exploration for me. This was my first 4 day trek and I can’t wait to do it again! Roberto was an amazing guide that offered the perfect blend of adventure with security, freedom with direction and fun with agenda. I saw amazing waterfalls, glaciers, natural hot springs, wildlife, and of course, mountains. Iceland offers an incredibly diverse landscape and Roberto orchestrated the perfect blend. Even if you’ve already visited Iceland 100 times, I am confident you will uncover more gems. I will remember this trip forever. Highly recommend taking a hike or trek with Hikers of Iceland.

Where can i even start from? The tour with the best guide Roberto has been just amazing. As soon as we arrived at the airport Roberto welcomed us kindly and reassuringly and made us start this awesome experience in his van!! I was a bit anxious on the tracking parts, but Roberto made them be comfortable, exciting and really funny. Every little problem encountered was solved with positivity and lots of laughter. Roberto took us to the most suggestive and marvellous places of Iceland, also the even the lesser known ones, accompanying us to the complete discovery of a culture rich in traditions and nature. At the end of the 10 days, we were all satisfied and so happy (a little sad to be leaving 😂). He made us love Iceland one waterfall at time! We saw almost the whole country, starting from Reykjavik, going into lagoons, glaciers, waterfalls, rivers, caves, beaches, volcanos, mountains, farms, canyons, forests, ocean, admiring starry skies and a lot of cute animals! A must for the ones who love travelling and exploring new countries, where you can see the 4 natural elements (water earth fire air)in their maximum expression, in a place where the man didn’t change or ruin them. Hikers of Iceland is the TOP, and Roberto is of course the best!

We had a fantastic trip in Iceland — Roberto took us off the beaten track to give us an authentic adventure while keeping us safe and entertained. A professional guide who gives great guidance to suit hikers of all levels. Highly recommend! Thank you, Roberto for a memorable trip trekking, glacier hiking, ice climbing, waterfall hunting, hot pool dunking and all your tips, jokes and stories.

As the Tour Leader of "Avventure nel Mondo" group trip, I couldn't be happier with our experience. Roberto guided us on the Sólheimajökull glacier and gave us a truly magnificent day. He is an extremely passionate and knowledgeable guide, and—just as importantly—always kind and smiling. The organization was impeccable: perfect punctuality, total respect for our agreements, and he provided all the necessary equipment to let us enjoy the hike in complete safety and comfort. He managed our large group with incredible ease, and his work was appreciated by every single member of the team. Ciao Roberto!

Hiking & trekking — questions people ask

When can you hike in Landmannalaugar?

Late June to September. The highland roads to Landmannalaugar are closed by snow the rest of the year, and the opening date shifts with the weather each summer. In season, day tours from Reykjavík (/experience/16823/) run about fourteen hours with a three- to five-hour guided hike and a soak in the hot river. If you have your own 4x4, the meet-on-location hike (/experience/254326/) skips the bus.

How hard is the Laugavegur trek?

Moderate to hard. It is 55 kilometres over four days from Landmannalaugar to Þórsmörk, with river crossings, snow patches in July and weather that can turn to sleet in August. You do not need technical skills, but you need to carry a pack and walk five to eight hours a day. Guided treks (/experience/738812/) handle logistics and camping gear; the luggage transfer (/experience/1036525/) lets self-guided walkers carry a day pack only.

Can you hike to the volcano near Reykjavík?

Yes, when it is safe. The Reykjanes eruption sites at Fagradalsfjall and around Grindavík have drawn hikers since 2021, and guided tours (/experience/629086/, /experience/620679/) follow the routes the Civil Protection authority has open. If there is an active eruption, access changes daily and tours adapt or pause. The lava is usually cooled and crusted; you see fresh black rock and steam, not flowing lava. Wear boots; the ground is rough.

What should I pack for a day hike in Iceland?

Waterproof jacket and trousers, not a poncho; the wind will shred it. Hiking boots with ankle support, wool or synthetic layers, hat, gloves, sunglasses and a packed lunch with two litres of water. In the highlands add a warm mid-layer even in July. Guides carry first aid and route knowledge, not your rain gear. Cotton jeans and trainers are the most common reason people have a miserable day.
