- East side (Route 864): Gravel road, rougher but gets closer to the edge
- Free parking on both sides with restroom facilities
- Walk from parking: 1-1.5 km to viewpoint (20-30 minutes)
When is the best time to visit Dettifoss?
- Summer (June-August): Best road conditions and longest daylight

- Mornings typically have fewer visitors and better light
- Winter access is limited: west road may be plowed, east usually closed
- Always check road.is before visiting; conditions change rapidly
Choose the approach, then the walk
The park’s Dettifoss guide distinguishes paved Route 862 on the west from gravel Route 864 on the east. Route 862 has limited winter service; 864 closes with autumn snow and reopens only when conditions, including drying mud, allow. A paved approach is not a promise of winter access.
For a longer visit, use the park’s named D2 Dettifoss-and-Selfoss circuit rather than treating the two waterfalls as unrelated stops. D3 into Hafragil lowland is a different proposition: the park rates it difficult and warns of steep ground and falling rocks. Choose that walk deliberately, not as an unplanned extension of the viewpoint path.
West-side route change: The park’s 25 May 2026 notice permanently closes Fosshvamm near Dettifoss after rockfall and hidden cracks. Views remain available, but paths are being relocated. Follow current signs rather than an older map into Fosshvamm; confirm the open connection before extending a walk to Selfoss.

Is Dettifoss wheelchair accessible?
The west side has a paved path and is more accessible, though the final viewing area can be rough. The east side is not wheelchair accessible due to rocky, uneven terrain.
Which side is better: West or East?
The West side is paved, easier to access, and gives a full frontal view (prepare to get wet). The East side is a gravel road, rockier, but gets you closer to the very edge of the drop.
Is the road open in winter?
Often no. The road to Dettifoss (especially the East side) is frequently impassable or closed due to snow in winter. The West side (862) is more serviced but still subject to closures. Always check road.is.
Can I see Selfoss too?
Yes, Selfoss (not the town) is a wide waterfall a 1-km hike upstream from Dettifoss. It's worth the extra walk.
