Discover stunning basalt formations, Iceland's deepest canyon, and a hot spring on this full-day guided tour from Seyðisfjörður, blending natural wonders and engineering marvels.
Exploring Iceland’s northeastern wilderness is no small feat, but for those wanting a well-rounded taste of the region’s extraordinary landscapes, the “From Seyðisfjörður: Stuðlagil Canyon and the Highland Circle” tour offers a compelling day out. Embarking from Seyðisfjörður or Egilsstaðir, this guided adventure takes you into some of Iceland’s most dramatic scenery—think towering basalt columns, fierce gorges, serene hot springs, and impressive hydroelectric infrastructure.
One thing we particularly appreciate about this tour is the variety it packs into just 9 hours. You’re not only treated to breathtaking natural sights but also get a glimpse of Iceland’s engineering feats, making the day both visually stunning and intellectually interesting. However, it’s worth noting that the hiking, especially at Stuðlagil, is described as moderately challenging, so it’s best suited for those comfortable on their feet and prepared for variable weather conditions.
If you’re someone who loves a mix of nature, adventure, and a dash of Icelandic ingenuity, this tour could be just what you’re looking for. It’s especially perfect for travelers who want a structured, guided experience that covers a lot of ground without the worry of logistics.

The tour kicks off with a pickup from either Seyðisfjörður at The Filling Station / Food Coop or from Egilsstaðir at Hús handanna craft & design shop. The group size is generally manageable, and the bus ride provides a comfortable, scenic prelude to the day’s adventures. Expect about an hour of travel to your first destination, giving you a chance to settle in and get excited.
Once you arrive at the newly renovated viewpoint at Grund, you’ll get your first breathtaking glimpse of Stuðlagil. The viewing platforms are carefully designed and safe, affording spectacular aerial views of the basalt columns and the river carved through them. The water’s color varies with the seasons—sometimes a vibrant blue-green—making each visit unique.
The hike to the canyon is moderately challenging, with some uneven terrain and possibly muddy patches, so sturdy hiking shoes are a must. We loved the way the tour balances hiking with the opportunity for quiet reflection and photography. A review mentioned that “the viewpoint allows you to really grasp the scale of the basalt formations without the strenuous trek down into the canyon itself,” which is ideal for those not keen on intense hikes but still wanting a good view.
After soaking in the views of Stuðlagil, the journey continues into the highlands to visit Hafrahvammagljúfur. This 200-meter-deep gorge is a sight to behold, and the fact that it’s also called the “Dark Canyon” hints at the deep shadows that play across its walls—perfect for photography buffs. The walk here is relatively easy and allows for ample time to marvel at the sheer scale and rugged beauty of the landscape.
Visitors have described it as “grand, almost intimidating,” and that it’s one of those spots where you understand just how wild Iceland’s interior can be. Since sunlight barely reaches its depths, it’s a place that invites quiet awe rather than bustling crowds.
A highlight for many is the stop at a hidden natural hot spring. It’s a bit of a secret spot, surrounded by wilderness, offering a chance to relax after some moderate hiking. It’s important to note that no changing facilities are available, so bringing a swimsuit and towel is advised if you want to dip in. One reviewer fondly recalled “the serenity of soaking in the warm water with only birds and wind for company,” which underscores the tranquil vibe of this stop.
On the return leg, the tour visits Hálslón reservoir and the Kárahnjúkar dam—an impressive feat of hydroengineering. This large-scale infrastructure is part of Iceland’s renewable energy story, and you’ll get a decent photo stop with views of one of Europe’s biggest hydro power plants. The guide might share insights into how this infrastructure powers Iceland and even exports energy to continental Europe.
One reviewer called this stop “a fascinating glimpse into how Iceland harnesses its natural resources,” highlighting the educational value this part of the tour offers.
After a full day of exploration, the bus heads back to the starting points in Seyðisfjörður or Egilsstaðir, with an estimated total duration of 9 hours. The experience is well-paced, with enough time at each stop to absorb the scenery and snap photos.

At $334 per person, this tour offers a comprehensive look at some of Iceland’s most striking landscapes combined with a taste of its energy infrastructure. Considering the transportation, guided commentary, and multiple stops, the cost is quite reasonable. It’s especially appealing for those wanting to maximize their day with diverse sights without the hassle of driving themselves.
While meals aren’t included, the tour starts with a convenient pickup and ends with a structured itinerary, making it straightforward for travelers who prefer guided convenience. If you’re prepared for some walking and variable weather, the experience delivers excellent value for those seeking an authentic look into Iceland’s natural and engineered wonders.

This experience is best suited for travelers who want a balanced mix of natural scenery and engineering insights. Nature lovers will enjoy the towering basalt columns and deep gorges, while those curious about Iceland’s renewable energy efforts will find the hydro plant stop compelling. The moderate hikes mean it’s suitable for most moderately fit travelers, but not ideal for anyone with mobility issues.
Families with kids comfortable on foot will find it engaging, and adventure seekers will appreciate the varied activities packed into a relatively short timeframe. It’s an ideal choice for travelers who want a full-day, guided exploration that combines outdoor adventure with cultural and technological insights.
