When it comes to canyons, Iceland punches well above its weight. These steep-sided valleys lure hikers away from the Ring Road and deep into the countryside, and with good reason. Often remote and unspoilt, sometimes fragile, and always breathtaking, Iceland’s canyons reveal dramatic rock formations, hidden waterfalls, and landscapes shaped by fire and ice.
While some canyons fit firmly on the classic tourist trail, others, even in the popular south, still feel properly off the beaten track. Many are easy to reach by rental car, with parking close to the trailhead. When you are ready to lace up your hiking boots and explore on foot, this guide covers the best canyon hikes in Iceland, with practical tips for self-drive travelers.

Stuðlagil Canyon
Locals often describe Stuðlagil as a hidden canyon, and until recently, it quite literally was. For decades, much of this gorge lay submerged beneath the Jökulsá á Dal river. That changed when a hydroelectric dam upstream reduced water levels, revealing one of Iceland’s most striking natural sights.
The canyon walls are formed from hexagonal columnar basalt, stained with rusty iron oxides that contrast beautifully with the charcoal rock beneath. What really steals the show, however, is the turquoise river, glowing vividly for most of the year.
You can explore Stuðlagil from both sides
- The west bank offers an easy walk from the car park to a staircase and viewing platform.
- For a more immersive hike, cross the bridge on the east side and follow a gravel path across meadowland. After a shallow stream crossing near Stuðlafoss, natural basalt steps lead down to the water’s edge
On a sunny day, this is widely considered one of the most photogenic canyon hikes in Iceland.
Almannagjá
You may not recognize the name, but almost every visitor to Þingvellir National Park walks through Almannagjá. This dramatic gorge forms part of the rift between the North American and Eurasian tectonic plates, which are slowly pulling apart beneath Iceland.
Driving yourself rather than joining a Golden Circle tour allows you to spend real time here. Towering rock walls rise on the western side, while the eastern edge opens onto sweeping views across the Þingvellir plains.
Almannagjá is also historically important. For centuries, this was where the Althingi Iceland’s ancient parliament, gathered to pass laws and settle disputes. Follow the canyon trail to Öxarárfoss, a compact but beautiful waterfall tucked into the rift.
Fjaðrárgljúfur
Known to many as Justin Bieber Canyon after featuring in the “I”ll Show You music video, Fjarðrárgljúfur lies close to Kirkjubæjarklaustur in South Iceland. It is easy detour from the Ring Road via a well-maintained gravel road.
A marked trail climbs along the canyon rim, offering elevated views of the winding river below, while a lower path near the bridge lets you experience the canyon at water level. Glacial meltwater carved this canyon into soft tuff rock over thousands of years, creating walls that rise more than 100 meters high.
The moss-covered slopes are extremely fragile, and the canyon closes periodically to allow vegetation to recover. Always follow signage and stay on marked paths.
Sigöldugljúfur
Like Stuðlagil, Sigöldugljúfur was revealed after hydroelectric development altered river flow. Located in Iceland’s central Highlands, this canyon is nicknamed the Valley of Tears due to the many waterfalls cascading down its steep sides.
The vivid contrast between turquoise water, lush green slopes, and dark volcanic rock makes this one of the Highlands’ most underrated hiking spots. The walk to the canyon rim takes around 30 minutes, but many hikers continue further for better views of Sigöldufoss, the main waterfall.
Access is only possible in summer when F-roads are open, and a 4×4 vehicle is required. River-level hiking is not recommended due to sudden water releases.
Stakkholtsgjá
Fans of Game of Thrones will recognize Stakkholtsgjá, where Jon Snow attempted to capture a wight. Set within the stunning Þórsmörk Nature Reserve, this canyon is flanked by towering palagonite cliffs coated in moss.
Reaching the trailhead involves river crossing the F249, which are not suitable for rental cars. As a result, this canyon is best visited on a guided tour from Reykjavík or the South Coast.
The hike itself is relatively easy, following a flat 2 km trail alongside a stream. At the end, a waterfall spills into a cave-like chamber, creating a dramatic finale.
Nauthúsagil
Another Þórsmörk highlight, Nauthúsagil, is accessible to 4×4 self-driver in summer without crossing rivers. Park before the crossings and hike in on foot.
Known as Bull Shed Ravine, this narrow canyon is shaded by arching rowan trees and features mossy rock walls and small waterfalls. It feels intimate and enclosed, offering a quieter alternative to some of Iceland’s larger canyons.
Jökulsárgljúfur including Ásbyrgi
Located along the Diamond Circle in North Iceland, Jökulsárgljúfur is home to some of the country’s most powerful waterfalls, including Dettifoss, Europe’s second powerful by volume.
Park on either side of the canyon and walk along the riverbank to feel the sheer force of Vatnajökull’s meltwater surging through the gorge. Nearby Selfoss offers a gentler but equally photogenic cascade.
Further north lies Ásbyrgi, a vast horseshoe, shaped canyon surrounded by forest. Legend claims it was formed by the hoofprint of Odin’s eight-legged horse, while science points to catastrophic glacial floods. Hiking trails connect Ásbyrgi with Dettifoss for those planning multi-day treks.
Múlagljúfur Canyon
Our final pick, Múlagljúfur, sits close to Jökulsárlón and Fjallsárlón glacier lagoons. A short gravel road off the Ring Road leads to the trailhead.
The out-and-back hike is around 5 miles (8km) and follows a clear but lightly marked path. The scenery more than justifies the effort, with sweeping views across the canyon and two standout waterfalls: Hangandifoss, plunging 123 meters, and Múlafoss further along the valley.
