Eystrahorn is a 756-meter-high mountain located at the outer end of Hvalnes, east of the Lón area in South-East Iceland. The mountain is a striking landmark, rising steeply from the surrounding coastal and sandy terrain.

Between Eystrahorn and Vestrahorn lies a long sandy beach, with two fjords or lagoons behind it: Papafjörður and Lónsfjörður. This creates a distinctive landscape shaped by the interaction of mountains, sea, and sand.

Eystrahorn is composed mainly of gabbro and granophyre and is of considerable geological interest. Various minerals have been found within the mountain, including gold, silver, and mercury, attracting attention from geologists over the years.

Historically, the mountain was known as Hvalneshorn, while Vestrahorn was called Eystrahorn. At the same time, the mountain Horn in the Hornstrandir region was referred to as Vestrahorn, reflecting how place names have changed over time.

The place can form part of a wider journey through South Iceland, making it easy to combine the visit with other destinations in the region.

Overview

Eystrahorn is a dark, jagged coastal mountain in Southeast Iceland with a markedly alpine appearance.

History

Its position near the southeast coast has made Eystrahorn a long-standing visual landmark in the Hornafjordur region. Cultural context: Eystrahorn contributes to the visual and cultural identity of its region and is part of the long relationship between Icelandic communities and mountain landscapes.

Geology

The mountain contains intrusive rocks such as gabbro, which crystallized at depth inside an ancient volcanic system before erosion exposed them.

Hiking

Hiking possibilities around Eystrahorn vary by route, season and access point. Exact distance and duration should be taken from a dedicated route record where available.

Safety

Conditions on Eystrahorn can change quickly. Wind, low cloud, rain, snow, ice and loose ground can all increase difficulty. Visitors should check current conditions and choose routes appropriate to their experience. Practical visitor information: Visitors should choose an experience that matches current conditions and their own experience

Interesting facts

Eystrahorn provides a rare surface view into rocks that originally formed deep underground. Understand Eystrahorn by noticing not just the summit, but also its rock, slopes, neighbouring landforms and position within the wider landscape. Notable features: The exposed intrusive rock and sharp ridges make Eystrahorn geologically and visually different from many layered basalt mountains elsewhere in Iceland.
