Best Day Hikes in Iceland

For hikers who want big views without committing to a multi-day trek, Iceland’s day hikes are perfect. From coastal paths to geothermal valleys, here are some of the best routes to explore. 

1. Mount Esja Trail

Mount Esja is one of the most popular hiking destinations in Iceland, with various routes graded from 1 to 3 in difficulty to choose from. The trails lead towards panoramic views of Iceland’s capital, Reykjavík. The trail is particularly popular with the locals and is a great opportunity to see what Iceland has to offer. Depending on which route you take and how fast you walk, the routes typically take between 2 and 4 hours. 

Beginners are advised to turn back after reaching Steinn, the well-known rock viewpoint, while more experienced hikers can continue toward the summit for even more impressive scenery. Little to no experience is required for this trail, but be sure to check the forecast as the weather can impact your overall experience.

2. Þingvellir National Park

Þingvellir National Park is the only place in the world where splitting tectonic plates can be seen above sea level, making it one of the most popular hiking destinations in Iceland. There are various trails that extend throughout the majority of the park. Opt for the most popular route from Hakið and you’ll enjoy fantastic views of Iceland’s largest lake, Þingvallavatn. 

Continue on this trail in Þingvellir National Park for around 30 minutes to catch a glimpse of the Öxarárfoss Waterfall. The water is crystal clear and refreshing, perfect for filling a water bottle! The waterfall is also a famous filming location for Game of Thrones, making it a memorable stop for anyone exploring the best treks in Iceland.

3. Reykjadalur Hot Spring Valley

This memorable hike is truly one of the most unique routes in Iceland. Located about an hour away from Reykjavík, the valley is home to a naturally heated geothermal river that you can swim in. Always make sure to check for signs, as some areas are too hot for soaking! Lush green grass covers the valley, and the steaming river winds through, creating a mystical, breathtaking landscape. 

While the trail is generally easy, the area can be slightly dangerous due to the unstable ground, so hikers should exercise caution. The hike takes roughly 3 hours to complete, giving you plenty of time to enjoy the scenery, soak in the river, and fully experience this one-of-a-kind adventure. 

4. Sólheimasandur Plane Crash

The hike to the Sólheimasandur plane crash site is about 5 miles (8 km) long and takes roughly 2-3 hours to complete. The hike is flat, making it one of the easier hiking trails in Iceland.

The US Navy DC plane wreck dates to 1973 and remains intact. Fortunately, no one died in the crash, so it’s safe to visit! The stark contrast of the white plane on the black sand creates a surreal scene, making it a uniquely photogenic spot and a popular tourist attraction in Iceland. This is one hike that offers an experience like no other.

Best Multi-Day Treks in Iceland

For adventurers seeking remote landscapes and immersive wilderness experiences, these legendary Iceland trekking routes belong at the top of your itinerary. 

1. Laugavegur Trek

The Laugavegur trek, listed as one of the world’s best hiking trails by National Geographic, is one of the most renowned routes in Iceland. This popular trail is roughly 34.1 miles (55 km) long and leads through some of the most beautiful parts of the Icelandic Highlands, far from any paved road or path. 

The trail begins in Landmannalaugar, a vibrant valley known for its colorful rhyolite mountains. Some of Iceland’s most active volcanoes lie close to the Laugavegur route, and there are several hot springs along the way where hikers can stop for a rejuvenating soak. 

Completing the trail typically takes four days, making it one of the most rewarding trekking routes in Iceland for multi-day explorers. Campsites and mountain huts are dotted along the way, offering overnight accommodation for both independent hikers and guided groups.

2. Fimmvörðuháls Pass

The Fimmvörðuháls pass route is one of the most dramatic treks in Iceland, taking hikers between glaciers, across volcanic terrain, and past countless waterfalls. This route stretches roughly 15.5 miles (25 km) and showcases some of the country's most diverse landscapes, from lush lowlands to steaming lava fields formed by the 2010 Eyjafjallajökull eruption.

This trail begins in Skógar and gradually climbs into the Highlands, between the Eyjafjallajökull and Mýrdalsjökull glaciers. Along the way, hikers can see newly formed craters and unique lava formations before descending into Þórsmörk Valley. 

The trek is usually completed in one to two days; however, adding extra nights in Þórsmörk allows additional time to explore the surrounding peaks. There are designated huts and campsites near the trail, but you’ll need to book your accommodation in advance as spots are limited. 

3. Hornstrandir Nature Reserve

The Hornstrandir traverse trek is one of Iceland’s most untouched adventures, offering a true escape into nature. Located in the Westfjords, this multi-day route covers roughly 37-43 miles (60-70 km) depending on the exact route taken and leads through dramatic sea cliffs, wildflower-filled valleys, and landscapes rich in wildlife. 

The journey typically starts in the abandoned village of Hesteyri, which is accessible only by boat, giving an immediate sense of isolation. This sense of expedition makes the Hornstrandir trek a favourite amongst experienced hikers. 

Most people complete the hike in 5-7 days, and the adventure should only really be attempted with an experienced guide or as part of a group tour. 

4. Víknaslóðir Trails

Also known as the “Trails of the Deserted Inlets”, the Víknaslóðir trails are a network of routes in Iceland’s remote Eastfjords. Covering approximately 50 miles (80 km), the trails wind through colourful mountains, old fishing villages, and quiet coastal valleys, offering a peaceful alternative to some of the more crowded trekking routes.

Most hikers set off from Borgarfjörður, a village rich in birdlife and known for one of the country’s best puffin-viewing spots. From there, well-marked paths offer an assortment of perspectives of the Eastfjords' distinctive beauty, including sweeping fjords and hidden coves. 

The tranquil trek can be completed over several days, with various camping options available along the way.

Iceland offers some of the most diverse and unforgettable hiking experiences in the world, from easy day trails suitable for all abilities to legendary multi-day treks for the experienced and adventurous. No matter your skill level, there’s a trail here waiting for you.
