Iceland has thousands of stunning waterfalls, but Dettifoss Waterfall in North Iceland stands out as the most powerful of them all.
If you’re planning a self-drive trip, this guide covers everything you need to know, including how to get there, which road to take, and the best rental car for the journey.
What Makes Dettifoss Waterfall So Special?
Dettifoss is known as the most powerful waterfall in Europe, making it one of the most dramatic natural attractions in Iceland.
- Width: 100 meters
- Height: 44 meters
- Average flow: about 193 cubic meters per second
The sheer force of the water crashing into the canyon below creates a raw, almost otherworldly experience. You’ll feel the ground and likely get soaked by the mist.
This is not just another stop. It’s one of the most unforgettable highlights of a North Iceland road trip.
Where Is Dettifoss Waterfall?
Dettifoss is located in Vatnajökull National Park in North Iceland.
Driving distances:
- From Akureyri: about 133 km (1 hour 45 minutes)

It’s part of the famous Diamond Circle route, which also includes:
- Goðafoss waterfall
- Lake Mývatn

This makes Dettifoss an great addition to a longer Ring Road itinerary.
How to Get to Dettifoss by Rental Car
Dettifoss is accessible from Iceland’s Ring Road (Route 1), making it ideal for a self-drive trip.
You’ll turn onto either:

Road 862 (West Side – Best for Most Travelers)
- Fully paved
