The top 3 geothermal areas on the Reykjanes Peninsula

Iceland’s well known for its remarkable geothermal activity. One of the country’s most famous visitor attractions, part of the Golden Circle, is the Haukadalur geothermal field. There visitors flock in their thousands to see a mighty geyser called Strokkur erupt, sending jets of boiling hot water and superheated steam soaring into the air every few minutes. It’s an incredible sight, but one that you’re guaranteed to have to share. For that reason, savvy visitors like to head to geothermal areas that are less well known, as they’re far more likely to find a quiet corner where they can marvel at the power of nature without their thoughts being interrupted by the chatter of others. In Reykjanes, there’s plenty of geothermal activity, so why not head to one of these areas and see for yourself how nature’s not yet finished creating this breathtakingly beautiful part of Iceland.

Seltún-Krýsuvík Geothermal Field 

The Seltún-Krýsuvík geothermal area is one of Reykjanes’ more colourful sights. Minerals and deposits from the area’s hot springs have stained the ground yellow, red, green, white and even blue. Follow a boardwalk through this geothermally active area to get a closer look. Steam rises from the ground beside you and bubbling mud pools plop. Nature is at her most active here and it’s an impressive sight, though you’ll have to put up with the whiff of sulphur on the air. Where overheated groundwater or volcanic activity has caused an explosion, you’ll see the evidence in the form of maars (craters). These craters flood, leaving lakes like Grænavatn, Gestsstadavatn and Augun (the Eyes). It’s well worth hiking to the top of the hill for the spectacular view over the ground and to the ocean beyond – ample reward for your efforts.

Gunnuhver Geothermal Area 

Gunnuhver Geothermal Area is a little different to other geothermal areas nearby – instead of the more usual freshwater springs, the groundwater here is solely comprised of sea water. Nevertheless, you’ll still smell that characteristic smell of sulphur. Many visitors find Gunnuhver Geothermal Area a spooky place as steam shrouds the area. Those who believe in ghouls know it as the place haunted by a woman named Gunna whose ghost was trapped in the hot springs centuries ago after she terrorised the locals. Whether you believe in such tales or not, it’s worth heading out here to admire Iceland’s largest mud pool. Measuring around 20 metres across, it’s a jaw-dropping sight. Make sure you stick to the paths, though, as temperatures soar well above boiling point and could cause serious injury.

The Blue Lagoon

The Blue Lagoon lies at the heart of a geothermal area on the Reykjanes peninsula but it’s completely different to the natural hot springs and mud pools of Seltún Krýsuvík and Gunnuhver because this spa complex is entirely manmade. Instead, this place harnesses the waste water from a geothermal energy power plant to form a pool for bathing. For decades it’s been one of the country’s premier spas, as its location close to Keflavik Airport makes it a first or last stop that’s as convenient as it is memorable. Sometimes, it takes a combination of nature and people to create something that’s truly special.
