Here are the top 10 hiking trails in Iceland:

Mount Súlur, the iconic twin-peaked mountain rising southwest of Akureyri, is a beloved symbol of the town and a classic hiking destination for locals and visitors alike. The peaks of Súlur stand sentinel over the “Capital of the North,” their pale rhyolite slopes a striking contrast to the lush valley below.

The most popular route begins at the end of Súluvegur road, where a parking area in Glerárdalur valley marks the start of the adventure. From here, the well-trodden trail leads you steadily upward, first through grassy meadows and then onto the open mountainside. The lower peak, Ytri-Súla, rises closest to town, while the higher, Syðri-Súla, stands at 1,213 meters and offers the ultimate summit experience.

Súlur’s geology is as fascinating as its views. The mountain is composed mostly of light-colored rhyolite, formed by volcanic activity in the ancient Öxnadalseldstöð volcanic system some 8–9 million years ago. As you climb, the landscape shifts from green slopes to rocky ridges, with the town of Akureyri and the shimmering waters of Eyjafjörður growing ever more distant below.

The ascent is steady but manageable for most hikers with a reasonable level of fitness. The round-trip hike covers about 10.5 km and takes 5–6 hours, with an elevation gain of over 900 meters. On clear days, the summit rewards you with breathtaking 360-degree views—across the fjord, over the town, and out to the distant highlands.

Multiple routes are possible, but the most common is from the Glerárdalur parking lot, following the marked path all the way to the top. The trail is free to use, and hikers can enhance their experience with the Wapp hiking app, which provides real-time navigation and information about the route.

Mount Súlur is best hiked from June to September, when the trail is clear of snow and the weather is most favorable. As always in Iceland, be prepared for rapidly changing conditions, and bring sturdy boots, warm layers, and plenty of water.

Whether you’re a seasoned trekker or simply seeking a memorable day above Akureyri, the Súlur hike offers a perfect blend of natural beauty, geological wonder, and panoramic vistas—a true gem of North Iceland.

Few places on Earth offer the chance to witness the birth of new land, but the Fagradalsfjall Volcano hike on the Reykjanes Peninsula is just such an experience—a living, breathing testament to Iceland’s fiery heart. Since its dramatic eruption in 2021, Fagradalsfjall has become a magnet for adventurers, geologists, and anyone drawn to the raw power of nature.

The hike begins near the parking areas at the end of the winding road from Grindavík, where well-marked trails lead you across a surreal landscape of mossy lava fields and black volcanic sand. The air is tinged with the scent of sulfur, and the ground beneath your boots is still warm in places—a reminder that this is a land in constant transformation.

As you approach the eruption sites, the scenery becomes otherworldly. Jagged rivers of solidified lava snake across the valley, their glossy black surfaces still steaming in the cool Icelandic air. In some years, you may even witness glowing lava flows or the distant rumble of new fissures opening—an awe-inspiring spectacle that draws visitors from around the world.

The main trails—often labeled as Routes A, B, and C—vary in length and difficulty, but all offer unforgettable views of the volcanic craters, fresh lava fields, and the rugged expanse of the Reykjanes Peninsula stretching to the Atlantic horizon. Along the way, you’ll pass viewpoints where you can safely observe the volcanic activity, take in the scale of the eruption, and marvel at the forces that continue to shape Iceland.

Fagradalsfjall is a hike for the senses: the heat radiating from the earth, the hiss of steam vents, the ever-changing colors of cooled lava, and the stark beauty of a landscape reborn. It’s a reminder of Iceland’s restless geology and a rare opportunity to walk where the world is still being made.

Due to the dynamic nature of the volcano, conditions can change rapidly. Always check the latest updates from local authorities before setting out, and follow marked trails and safety guidelines. Bring sturdy footwear, layers for changing weather, and plenty of water—there are no facilities on the trail.

For those who make the journey, hiking Fagradalsfjall is more than a walk through a volcanic valley—it’s a front-row seat to the creation of a new world, and an experience that will linger long after the hike is done.

Tucked away in the far-flung Eastfjords, the Víknaslóðir trail network—known as “The Trails of the Inlets”—offers a hiking experience that feels like stepping into a secret world. Centered around the charming fishing village of Borgarfjörður eystri, these trails weave through a landscape of vivid rhyolite peaks, deep green valleys, and secluded coves where the Atlantic meets the wild Icelandic coast.

The Víknaslóðir network is a hiker’s paradise, with routes ranging from gentle day hikes to ambitious multi-day adventures. Trails are well-marked and interconnected, allowing you to tailor your journey to your own pace and interests. Along the way, you’ll pass abandoned farmsteads, silent witnesses to a bygone era, and traverse mountain passes that open onto sweeping views of the fjords and the endless sea.

One of the highlights is the hike to Stórurð (“The Giant Boulders”), a surreal valley filled with turquoise ponds and massive, moss-covered rocks—an otherworldly scene that feels plucked from a fairytale. For those seeking solitude, the remote inlets of Breiðavík, Húsavík, and Loðmundarfjörður offer peaceful campsites and a chance to truly disconnect from the modern world.

Wildlife lovers will delight in the thriving puffin colonies near Borgarfjörður eystri, where thousands of these charismatic birds nest each summer. The area is also rich in folklore, with tales of elves and hidden people woven into the very fabric of the land.

Víknaslóðir is best explored from late June to September, when the trails are clear of snow and the days are long. Whether you’re wandering for a few hours or embarking on a week-long trek, the Trails of the Inlets promise a journey through some of Iceland’s most enchanting and untouched landscapes.

The trailhead is easily accessible by car or public transport, making Esja one of the most popular day hikes in Iceland.

The hike begins at the Esjuraetur parking area, where well-marked paths wind their way up the mountain’s flanks. The lower slopes are gentle, meandering through birch groves and wildflower meadows, with the city skyline and Faxaflói Bay gradually unfurling behind you. As you ascend, the trail becomes steeper and rockier, offering a satisfying challenge for those seeking a bit of adventure.

A series of signposts guide you to “Steinn,” a large rock that marks the traditional turnaround point for many hikers. Here, you’re rewarded with sweeping, cinematic views over Reykjavík, the shimmering Atlantic, and—on clear days—the distant Snæfellsjökull glacier. For the more intrepid, the path continues to the summit, where the panorama is even more breathtaking, though the final stretch can be slippery and exposed, especially in winter.

Mount Esja is a hike for all seasons.
