Bruarfoss: Iceland's Bluest Waterfall

Hidden away in Iceland's Golden Circle region, Bruarfoss stands as perhaps the most ethereally beautiful waterfall in a country renowned for its cascading waters. Unlike the thunderous giants of Gullfoss or Skógafoss, this relatively modest 2-metre-high waterfall captivates visitors with its extraordinary cobalt-blue waters and intricate network of turquoise pools—earning it the well-deserved moniker of Iceland's bluest waterfall.

The name Bruarfoss translates to "Bridge Falls," a reference to the natural stone bridge that once spanned the Brúará River above the waterfall. Though this bridge collapsed in the early 20th century, its legacy lives on in both the waterfall's name and the man-made footbridge that now allows visitors to cross the river safely.

The Phenomenon Behind the Blue

The mesmerising blue hue that makes Bruarfoss so distinctive results from a fascinating interplay of glacial sediment, mineral content, and light refraction. The Brúará River carries fine glacial flour—microscopic particles ground by the Langjökull glacier—which scatters light in the blue spectrum more effectively than other wavelengths. The shallow, rocky pools above and below the falls further intensify this effect, creating an almost supernatural palette of blues and turquoises that shift throughout the day as light conditions change.

This phenomenon is most pronounced during midday hours when the sun is highest, though many photographers prefer the softer blues that emerge during golden hour. The contrast between the vivid waters and the dark volcanic rock creates some of Iceland's most striking natural compositions.

Getting to Bruarfoss

Bruarfoss lies approximately 105 kilometres northeast of Reykjavík, making it an accessible addition to any Golden Circle itinerary. The trailhead is located off Route 37, roughly 8 kilometres east of the village of Reykholt. From Reykjavík, drive northeast on Route 36 towards Þingvellir, then continue on Route 365 and finally Route 37.

Park at the designated area near coordinates 64.2629° N, 20.5180° W—look for a small gravel pull-off with space for approximately 20 vehicles. Parking is free, though the limited capacity means arriving early is advisable, particularly during summer months.

The Hike

The trek to Bruarfoss covers approximately 4 kilometres return and takes most visitors 1.5 to 2 hours to complete. The trail is relatively flat but can be muddy and uneven, particularly after rainfall. Sturdy hiking boots are essential, as are waterproof layers—Icelandic weather can change rapidly even during summer.

The path initially follows the Brúará River upstream, passing several smaller cascades and brilliant blue pools that serve as a preview of the main attraction. After roughly 2 kilometres of walking along sometimes indistinct paths marked by occasional cairns, you'll reach the wooden footbridge that signals your arrival at Bruarfoss.

Planning Your Visit

Best Time to Visit

Bruarfoss is accessible year-round, though each season offers distinct advantages. Summer months (June through August) provide the most comfortable hiking conditions and longest daylight hours—essential for photography. The midnight sun effect means you can visit well into the evening hours, when tourist numbers dwindle and you're more likely to have the falls to yourself.

Winter visits (December through February) present their own rewards, as ice formations frame the flowing water in spectacular fashion. However, the trail becomes significantly more challenging, requiring microspikes or crampons for safe passage. Winter daylight is limited to roughly 4-5 hours, so plan accordingly.

Spring (April-May) and autumn (September-October) offer excellent middle ground, with fewer crowds and dramatic skies that enhance the waterfall's natural beauty. Autumn provides the added benefit of potential aurora borealis viewing if you're camping nearby.

Photography Tips

Bruarfoss ranks among Iceland's most photographed waterfalls, and for good reason. For optimal results, bring a polarising filter to reduce glare and enhance the water's blue saturation. A tripod is invaluable for long-exposure shots that smooth the water flow while maintaining sharp detail in the surrounding rocks.

The most iconic shots are captured from the wooden footbridge, looking downstream towards the main falls. However, don't neglect the upstream pools and smaller cascades, which often produce equally stunning compositions with fewer crowds.

Safety Considerations

While Bruarfoss may appear benign compared to Iceland's more dramatic waterfalls, standard safety precautions apply. The rocks around the falls become extremely slippery when wet, and the water temperature remains frigid year-round—typically 2-4°C even in summer.

The trail lacks formal safety barriers, so maintain a respectful distance from cliff edges and fast-flowing water. Mobile phone coverage is patchy along the route, making it essential to inform someone of your hiking plans before departure.

Combining with Other Attractions

Bruarfoss's location makes it an excellent addition to classic Golden Circle touring. The nearby Geysir geothermal area lies just 15 kilometres to the southeast, while Gullfoss—Iceland's most famous waterfall—is merely 20 kilometres away. This proximity allows visitors to experience both intimate beauty and raw natural power within the same day.

Consider combining your Bruarfoss visit with the Reykjolt area's geothermal hot springs, including the historic Snorralaug pool where medieval scholar Snorri Sturluson once bathed. These natural hot pots provide welcome warmth after hiking to the waterfall.

Bruarfoss represents Iceland at its most sublime—a place where nature's artistry creates something so beautiful it seems almost impossible. While it may lack the raw power of Iceland's most famous cascades, its ethereal blue waters and intimate setting offer something equally valuable: a moment of quiet wonder in one of Earth's most spectacular landscapes.
