Quick Answer
Hágöngulón is a remote highland reservoir at about 820 m elevation near the northwestern edge of Vatnajökull. Summer 4x4 access only; no services in the area.
Hágöngulón sits at roughly 820 meters elevation in the shadow of Vatnajökull, Europe's largest glacier. The reservoir was created by damming the Kaldakvísl river for hydroelectric power, and it is surrounded by a raw landscape of glacial gravel, volcanic sand, and distant ice caps. Reaching it means driving some of Iceland's more difficult F-roads, including river crossings. Few places in the country feel as isolated.

What to Expect
Vatnajökull Views
On clear days, the ice cap of Vatnajökull dominates the southeastern horizon.
Highland River Crossings
The journey to Hágöngulón involves crossing glacial rivers. Water levels vary with weather and time of day. Experience and a capable vehicle are essential.
Volcanic Desert Landscape
The terrain around the reservoir is bare: black volcanic sand, gray gravel plains, and scattered rhyolite mountains in muted colors.
Total Silence
There is no human habitation for dozens of kilometers. Only wind and occasional bird calls break the stillness.
Hydroelectric Infrastructure
The dam and its works are the only human marks on the landscape. They feed power stations downstream on the Þjórsá system.
Midnight Sun Wilderness
In midsummer, the midnight sun circles the horizon and casts long golden light across the reservoir and surrounding highlands through the night.
Getting There
Hágöngulón is accessed via highland F-roads from the Sprengisandur route (F26) or from the Landmannalaugar area. The roads are rough and involve multiple river crossings that can be dangerous during heavy rain or rapid glacial melt. A robust 4x4 vehicle with high clearance is absolutely essential. Travel in convoy with at least two vehicles when possible. There are no fuel stations, shelters, or services anywhere near the reservoir. GPS navigation is strongly recommended as trails can be faint and unmarked. The nearest services are many hours of driving away.
Best Time to Visit
For a road trip, confirm the highland road opening and conditions for the actual date of travel. Do not use a general summer season as permission to drive a closed route. Even in summer, temperatures can drop near freezing with strong winds and sudden fog. Snow is possible at any time of year at this elevation. Always check road.is for current conditions and inform someone of your travel plans before heading into the highlands.
Where the stored water goes
Landsvirkjun’s account of the catchment dates Hágöngulón’s construction to 1997–1999 and lists its area as 37 km². It stores water from the Kaldakvísl catchment. Water from this reservoir passes through Þórisvatn before supplying the stations farther downstream.
The operator describes summer as a period of accumulation in Hágöngulón, with little water continuing down the Kaldakvísl riverbed. A low-flow river view therefore needs that operating context; it is not enough to infer the reservoir’s condition from a photograph of the channel. The published area is a descriptive reservoir figure, not a live shoreline measurement.

Hágöngulón FAQs
Quick answers with safety notes where it matters.
How remote is Hágöngulón?
Hágöngulón is one of Iceland's most remote lakes, located deep in the central highlands near the northwestern edge of Vatnajökull glacier. There are no permanent settlements, services, or phone signal in the area. Only experienced highland travelers with proper 4x4 vehicles should attempt the journey.
When can I visit Hágöngulón?
Plan a visit only after confirming that the full highland approach is open and suitable for your vehicle. Snowmelt, weather and road conditions determine access; a fixed calendar window is not a road-opening notice.
Is Hágöngulón a natural lake?
Landsvirkjun dates construction to 1997–1999 and gives the reservoir area as 37 km². Water stored here passes through Þórisvatn before supplying the downstream hydropower system.
What should I bring when visiting Hágöngulón?
Bring all fuel, food, water, and emergency supplies. A well-equipped 4x4 vehicle with good tires is essential. A GPS navigation device is strongly recommended as phone signal is nonexistent. Carry warm, windproof clothing even in summer, as highland weather is unpredictable.
