Ziplining in Hveragerdi: 1 km Svartagljufur gorge ride

Fly 1 km through a gorge and land with the geothermal valley in view

Zip line through Svartagljufur gorge in Hveragerdi on a 1 km ride—one of Europe's longest—with a custom harness, helmet and English-speaking guide. You stand on a sightseeing deck first to take in the waterfall and the landscape, then ride the line itself. The route passes the trailhead to Reykjadalur valley, known for its geothermal hot springs. The whole activity runs 50 minutes.

The Experience

The ride starts at 1 km—long enough that the gorge unfolds beneath you instead of flashing past. You get fitted with a custom harness and helmet, then climb to the sightseeing deck to see Svartagljufur's waterfalls and the surrounding Icelandic terrain before you zip. From there you launch into the gorge itself, moving fast enough to feel the speed but controlled enough that the landscape stays visible. The conventional ride is the most popular way to run this line, and it is what most people choose when they book.

The activity takes 50 minutes start to finish. Children from age 9 can ride, and the guide speaks English throughout. You need to weigh between 30 and 120 kg (66 to 264 pounds) to participate. The route passes the trailhead to Reykjadalur valley, where geothermal hot springs feed into a river—you see it from the air but the activity itself stays on the zipline.
