Aldeyjarfoss – Basalt Columns in Iceland
A dramatic highland waterfall where white glacial water crashes through dark basalt column walls
Updated February 1, 2026By the Iceland.org Travel Team
Location
North Iceland (Highlands)
Highland F-road access, Skjálfandafljót river
Aldeyjarfoss is one of Iceland's most visually striking waterfalls, located in the northern highlands where the powerful Skjálfandafljót river plunges 20 meters through a narrow gap in a vast basalt column amphitheater. What makes Aldeyjarfoss extraordinary is the contrast: milky-white glacial water, carrying sediment from the Vatnajökull ice cap, crashes into a dark pool surrounded by curved, twisted, and perfectly hexagonal basalt columns. The formations here are unusually varied, with some columns bending at dramatic angles, others standing ramrod straight, and intricate honeycomb patterns visible in cross-section. The remote highland setting adds to the otherworldly atmosphere, rewarding those who make the effort to reach it via F-road.

Sources to check
Road Access
F-road (4x4)
Accessed via Highland road F26 (Sprengisandur) or a gravel road from Route 842.
Access Season
Late Jun – Sep
F-roads typically open late June and close by October, depending on conditions.
What to Expect
Stunning Color Contrast
The milky-white glacial water against jet-black basalt creates one of Iceland's most dramatic natural color contrasts, enhanced by the frothy cascade.
Varied Column Formations
Unlike uniformly straight columns elsewhere, Aldeyjarfoss features columns that curve, twist, and bend in unusual directions due to complex cooling conditions.
Basalt Amphitheater
The waterfall drops into a deep natural amphitheater completely encircled by basalt columns, creating an enclosed, cathedral-like atmosphere.
Remote Highland Setting
The location in the northern highlands means fewer visitors and a sense of wilderness solitude that enhances the experience.
Same River as Goðafoss
Aldeyjarfoss is upstream from the famous Goðafoss on the Skjálfandafljót river, making a combined visit possible for 4x4 travelers.
Photographer's Dream
The interplay of white water, dark geometric stone, and often overcast highland skies creates exceptional conditions for dramatic landscape photography.
Getting There
Aldeyjarfoss is located in the northern highlands of Iceland on the Skjálfandafljót river. The primary access is via F-road F26 (Sprengisandur route), which requires a 4x4 vehicle. From Akureyri, drive east on Route 1 to Route 842, then continue south to where it becomes F26. The waterfall is signed along the road. An alternative shorter approach exists from Route 842 via a gravel track. From the parking area, a short walk of about 10 minutes leads to the waterfall viewpoints. Always check F-road opening status at road.is before attempting the journey, and never drive F-roads in a standard 2WD rental vehicle.
Best Time to Visit
Aldeyjarfoss is only accessible when F-roads are open, typically from late June through September. July and August offer the most reliable road conditions and longest daylight. The glacial water is most voluminous in mid-summer when meltwater peaks, creating the most powerful cascade and whitest water. Early morning or evening light can dramatically enhance the contrast between the white water and dark basalt. Overcast days, common in the highlands, actually produce some of the best photographs by reducing harsh shadows and saturating the basalt's dark tones. Check weather forecasts for the highlands specifically, as conditions can differ significantly from lowland areas.
