Glanni Waterfall

Where Water Meets Lava

Glanni sits at the point where the Norðurá river meets the ancient Grabrok lava field, and the result is a waterfall that looks unlike any other in Iceland. Instead of a single dramatic plunge, the river splits into multiple channels as it cascades over and between dark lava formations. The water is crystal clear — tinted blue-green by the volcanic minerals — and the contrast with the black rock is striking.

The name Glanni means "shining" or "glittering," and on a sunny day it earns it. Light plays across the broken surface of the water as it tumbles through the lava, creating a constant shimmer. In Icelandic folklore, the pools below the falls were said to be the home of elves and hidden people.

The Setting

The waterfall sits within a landscape of lava, birch woodland, and grassland. The Grabrok lava field, formed by an eruption roughly 3,000 years ago, surrounds the area with rough, moss-covered volcanic rock. Between the lava formations, birch trees have taken root, creating a green corridor along the river that feels surprisingly sheltered and peaceful.

A walking trail leads from the parking area through the birch woodland to several viewpoints above and beside the falls. The path is well maintained and suitable for most visitors. The sound of the river accompanies you throughout, growing louder as you approach the main cascade.

Salmon River

The Norðurá is one of Iceland's finest Atlantic salmon rivers, and anglers come from around the world to fish its pools. The clear water makes it possible to spot salmon holding in the pools below the falls — large, silver fish waiting to leap upstream. Fishing permits are tightly controlled and can be expensive, but watching the salmon run (typically in July and August) is free for everyone.

Getting There

Glanni is on Route 1 near the village of Bifrost in West Iceland, approximately 130 kilometres from Reykjavik (about 1.5 hours driving). The parking area is signed from the road. Combine with a visit to Grabrok crater (a 15-minute hike to the rim) and the nearby Hraunfossar lava waterfalls for a half day of exploration in the Borgarfjordur area.
