Waterfall Height
20 m (66 ft)
The Skjálfandafljót river drops 20 meters through a basalt-lined gorge into a deep pool.
Aldeyjarfoss: Basalt-Column Waterfall in North Iceland
A highland waterfall where white glacial water drops between dark basalt column walls
Location
North Iceland (Highlands)
Highland F-road access, Skjálfandafljót river
Aldeyjarfoss lies in the northern highlands, where the Skjálfandafljót river plunges 20 meters through a narrow gap in a basalt column amphitheater. The draw is the contrast: milky-white glacial water, carrying sediment from the Vatnajökull ice cap, falls into a dark pool surrounded by curved, twisted, and hexagonal basalt columns. The formations are unusually varied; some columns bend at sharp angles, others stand straight, and honeycomb patterns show in cross-section. The remote setting and F-road access keep visitor numbers low.

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
Color Contrast
The milky-white glacial water against jet-black basalt is the waterfall's defining feature, and the reason most people make the trip.
Varied Column Formations
Unlike the uniformly straight columns elsewhere, Aldeyjarfoss has columns that curve, twist, and bend in unusual directions, the result of complex cooling conditions.
Basalt Amphitheater
The waterfall drops into a deep natural amphitheater completely encircled by basalt columns.
Remote Highland Setting
The location in the northern highlands means far fewer visitors than the roadside waterfalls, and often no one else at all.
Same River as Goðafoss
Aldeyjarfoss is upstream from Goðafoss on the Skjálfandafljót river, so travelers with a 4x4 can combine the two.
Photography
White water, dark geometric stone, and often overcast highland skies make good conditions for 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 flow peaks in mid-summer with the meltwater, when the cascade is most powerful and the water whitest. Early morning or evening light sharpens the contrast between the white water and dark basalt. Overcast days, common in the highlands, often photograph well; they reduce harsh shadows and deepen the basalt's dark tones. Check weather forecasts for the highlands specifically, as conditions can differ significantly from lowland areas.
