Mount Esja, commonly referred to simply as Esja, is a mountain located on the Kjalarnes peninsula, today within the city limits of Reykjavík. The mountain is one of the most recognisable natural landmarks of the capital area and forms a dramatic backdrop to the city.

Views of Mount Esja have long influenced the identity of Reykjavík, and many locals claim they can predict the weather by observing the changing colours of the mountain. The highest peak reaches 914 metres above sea level, making Esja the southernmost basalt mountain in Iceland.

Several well-marked hiking trails lead up the mountain, making Esja one of the most popular outdoor recreation areas in the country. Common routes include the trail to Steinn, the ascent toward Móskarðshnúkar, and hikes continuing along the ridge. The highest visible ridge from Reykjavík is known as Kerhólakambur.

Mount Esja is closely connected to Icelandic history and folklore. In the medieval Kjalnesinga Saga, the farm Esjuberg is mentioned as the home of the settler Örlygur Hrappsson, who arrived in Iceland from the Hebrides of Scotland.

The saga also tells of an Irish woman named Esja who arrived at Kollafjörður, leading some to believe the mountain’s name has Celtic origins. However, it is considered more likely that the name derives from an Old Norse word meaning “slab stone”, a term also found in Norway.

Numerous attractions lie close to Mount Esja, including Mosfellsbær, Meðalfellsvatn, Úlfarsfell, Hafrafell, Hafravatn, Mosfell Church, and the historic geothermal pool Varmárlaug.

Rising directly across the bay from Reykjavík, Mount Esja is an essential part of daily life in the capital — a constant presence, a popular hiking destination, and a powerful symbol of Icelandic nature.

Overview

Esjan is the dominant mountain range on the northern skyline of Reykjavik and one of the capital region's best-known natural landmarks.

For centuries Esjan has been used as a reference for weather, seasons and direction by people living around Reykjavik and Mosfellsbaer. Cultural context: Esjan 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 is built from repeated basalt lava flows with sedimentary layers between them. Glaciers and rivers later cut deep valleys and gullies into the old volcanic pile.

Hiking
