The 7 Best Day Hikes in Iceland

There’s no doubt that most travelers come to Iceland to experience otherworldly nature. From the glittering glaciers to jagged mountains framed by geothermal plumes, there’s no shortage of wonderful scenery to take in during a campervan trip to the country.

If you want to immerse yourself in the awesome nature of Iceland, a day hike is one of your best options. It’s all about getting out there and putting yourself in the middle of these powerful landscapes – something that’s easier to do here than in any other country. To get you started, here are 7 of the best day hikes in Iceland.

While our guide focuses on exhilarating single-day hikes, if you're seeking more extensive adventures, consider delving into our dedicated resource on Iceland multi-day hikes. Dive into both guides and let the expertise on "Iceland multi-day hikes" be your key to unlocking the full spectrum of hiking adventures in this extraordinary land.

1. Fimmvörðurháls Pass (South Iceland)

One of the most popular day hikes in Iceland is the Fimmvörðurháls Pass, and with good reason. This trail crosses the mountain pass between two glaciers, Eyjafjallajökull and Mýrdalsjökull, taking you from the waterfall Skogafoss into the incredible Thórsmörk Nature Reserve.

It’s a long day hike, stretching for 25km over the towering mountain pass. The scenery along the way is incredible, with waterfalls, epic lava formations, volcanic craters, and views of the glaciers and surrounding landscape. As you descend into Thórsmörk valley, the scenery is even more stunning. Jagged valleys filled with moss-laden cliffs and sparkling glacial rivers cut through beds of black sand and birch forests, with the ever-present glaciers glittering above.

It’s a long hike, taking anywhere between 8 and 14 hours, depending on your fitness level. Once you’ve arrived in Thórsmörk, you’ll either need to get the bus back out to your campervan or stay a night or two for some more epic hiking.

2. Reykjadalur Hot Spring River (South Iceland)

One of the most pleasurable aspects of journeys around Iceland is soaking in the country’s hot springs. There’s a wealth of hot water bubbling forth from underground and being channeled into the swimming pools and hot tubs across the country, making for some steamy soaks after a long hike. The Reykjadalur hot spring river combines the two, making for a perfect day hike in Iceland.

Reykjadalur is a valley found in the mountains behind the town Hveragerði, just before you reach Selfoss. A river flows through the lush valley, perfectly warmed, thanks to the geothermal activity in the area. The hike itself takes you past steaming craters filled with mud and bright blue pools of water (far too hot to go swimming in). Eventually, you’ll reach the part of the river that sits at a comfortable temperature, surrounded by boardwalks and partitions for changing.

3. Glymur Waterfall (West Iceland)

Another popular day hike in Iceland is the trail that leads to the waterfall Glymur. This waterfall is exceptionally beautiful, charging off a cliff to fall 90 meters into the gorge below, filled with dark rocks contrasted by the bright green moss and white birds who nest there.

The hike itself first meanders along the shores of the river, which, at one point, you’ll have to cross via a log with a cable handy to keep your balance. From then on, the trail gets a bit more difficult, tracking up and down some muddy hills before a steady descent up one side of the gorge. Once at the top, the waterfall reveals itself at the gorge’s base, crashing down over the edge and disappearing into the riot of black rocks, bright green moss, and whirling birds below.

Once you’ve reached the waterfall, the hike isn’t over yet. One of the coolest things to do is to make your way above the waterfall itself and wade across the river, where it’s shallow. It’s a popular way to mark the top of the hike, and this way, you’ll also get to come down the other side of the gorge to reach your campervan waiting below.

4. Mt. Esja (Capital Area)

One of the most popular day hikes in Reykjavik is the trail that leads up Esja, the gorgeous mountains seen across the water from downtown. It’s a rite of passage for those living in the city, too, so if you want to feel like a true local and have a spare day before or after your campervan trip, this is the day hike for you.

The trail begins right next to the road leading out of town, heading toward Borgarnes. It’s steep, but the views along the way are well worth the trouble, taking in the capital and surrounding coastlines. Eventually, you’ll reach a large stone with a guestbook you should sign, but it isn’t the end of the hike.

The final scramble to the top should only be attempted in fair weather and when the wind isn’t blowing too strongly – otherwise, it can be dangerous. If you make it up there, you can enjoy panoramic views of the area, which is one of the most special views in Iceland. At the trailhead, there’s also a café serving hearty Icelandic fare, from soups to waffles and coffee.

5. Stórurð (East Iceland)

One of the most underrated day hikes in the entire country is the trail that leads you to the area known as Stórurð in the country’s eastern region. East Iceland itself sees very few visitors, with campers usually only spending a night or two in the region before coasting off to the more popular north and south areas for some adventure. But this day trek is a worthy addition to any Ring Road campervan itinerary you’ve planned.

Stórurð roughly means ‘large rubble’ in English, and that’s pretty much exactly what awaits you at the end of the trail. The area was likely created by a landslide in the ice age, sending large boulders tumbling across the mountainous landscape and into the bright blue glacial pools dotted across the area. To get there, the trailhead begins at a place called Njarðvík (GPS: 65°33.05 -13°58.24) and takes about 3–4 hours one way.

6. Geldingadalir Volcano (Reykjanes Peninsula)

The newest day hike in Iceland is the hike to the Geldingadalir Volcano.

Due to the nature of the volcano, this day hike has gone through many different variations. As lava continued to flow over the trails made by the Icelandic Search and Rescue Team, new ones were carved out, providing access to view the lava fields and, if you go far enough, the volcanic crater itself.

The Geldingadalir volcano is easily accessed from Reykjavik, located on the Reykjanes Peninsula. To find out more information, we’ve written a detailed guide about visiting the volcanic eruption in Iceland.

7. Skaftafell (Southeast Iceland)

The Skaftafell Nature Reserve in South Iceland is one of the hottest hiking destinations in the country. With easy access right off the ring road, this area should be on your bucket list if you’re an avid hiker looking for some excellent day treks in Iceland. Most people stop here for a fly-by visit of the waterfall Svartifoss, and while impressive, it’s only an hour and a bit return hike. For something a bit more time-consuming and rewarding, we highly recommend heading up to the peak of Kristínartindar mountain.

This is around a 17.9km round trip, so make sure that you’re prepared for the weather (things can turn quickly) and are carrying enough food and water for the day, as it will take around 7-8 hours. From the top of the mountain, you’ll be able to enjoy incredible views of the Vatnajökull Glacier and, on a clear day, Morsárfoss, Iceland’s tallest waterfall.

Conclusion

Hiking in Iceland is more than just a walk—it’s a way to dive into the heart of this incredible landscape. Each trail offers something unique, from the raw power of a volcanic eruption to the peace of hidden glacial pools or the thrill of towering peaks. Whether you're tackling a challenging climb like Fimmvörðurháls or soaking in a hot spring after a hike in Reykjadalur, these trails let you experience Iceland’s wild beauty up close. Lace up your boots, take it slow, and enjoy every step—there’s no better way to connect with the land of fire and ice.
