Suðurnes: Geology, Coast and Culture

The Mid-Atlantic Ridge is visible at a special point in Reykjanes UNESCO Global Geopark: here, it is the only place in the world where the ridge rises above sea level. In Suðurnes, you can combine this geological feature with coastal landscapes, historic sites and outdoor activities.

Geology along the Mid-Atlantic Ridge

The Reykjanes Geopark Visitor Centre focuses on the formation of the Reykjanes Peninsula and offers an engaging introduction to its geology and nature. The geopark also includes 55 designated geosites associated with the Mid-Atlantic Ridge and the effects of tectonic plates. This means the geological themes are explored not only in an exhibition, but also at the designated geosites.

A striking geothermal site is Gunnuhver. It is home to Iceland’s largest mud pool, measuring 20 metres in diameter. Two ramps at the Gunnuhver group offer views down to the spring and across the surrounding geothermal area, taking in both the mud pool and its surroundings.

Brimketill is another geological feature: this small pool was naturally shaped by marine erosion and lies at the edge of the lava coast west of Grindavík. The viewing platform is only a few steps from the car park. Coastal conditions and access to the platform can change; follow local safety guidance.

Hikes and Coastal Trails

Skógfellavegur is an approximately 11-mile coast-to-coast trail between Vogar and Grindavík. The route is estimated to take around four to six hours; conditions may vary. By contrast, the trail to Keilir leads from the car park along a gravel path to the summit of the 378-metre-high volcanic plug. Allow two to three hours. The estimated times highlight the difference between the two hikes: the Keilir trail takes less time than Skógfellavegur.

A marked trail also leads to the Hafnarberg cliffs, starting at a car park on Route 44. In strong winds or bad weather, conditions on the cliffs can be dangerous. Take this into account when planning your visit and follow local guidance.

Buildings and History

The surviving church at Hvalsnes was built from dressed stone sourced from the surrounding area. Inside the church is the gravestone of Steinunn Hallgrímsdóttir, who died in 1649; her gravestone was rediscovered in 1964. The site thus brings together a surviving building and a specific historical connection.

The new Reykjanes lighthouse was built on Bæjarfell in 1907–1908. Stekkjarkot offers a different glimpse of how early coastal houses were built: it is a classic example of roughly constructed cottages made of turf, stone and wood, once common on the Reykjanes Peninsula and in other coastal areas of Iceland. Visits are available by request.

Nature, Exhibitions and Local Experiences

The Sudurnes Science and Learning Center is located in Suðurnesjabær. Its natural history gallery features taxidermied animals from Iceland’s wildlife and live marine animals. The centre also offers a treasure hunt featuring animals, plants and historic sites. Opening hours vary by season; check the latest opening information before your visit.

Urta Islandica focuses on products made with local Icelandic ingredients: the company produces artisan teas, syrups, salts and jams. Visitors can view the production line in the shop. Outdoor activities on Reykjanes include hiking and cave exploration. Kayaking, boat trips and diving are also available. Providers and seasonal availability may change for these activities; check the latest details in advance.

Plan Your Visit and Getting There

The Blue Lagoon is a wellness and geothermal spa on the Reykjanes Peninsula, featuring warm geothermal seawater. As current access arrangements may change, check them before your visit.

For bus travel, Route 55 is a useful connection: it runs from Keflavík Airport via Reykjanesbær to Reykjavík and the University of Iceland. Routes and timetables may change, so check the latest service details before travelling. If you are planning a hotel stay, you can shape your daily itinerary around different interests, such as hiking, geothermal sites, coastal landscapes or cultural history.
