Seltún

Background

History & Background

Seltún is part of the Krýsuvík geothermal system, one of several high-temperature geothermal zones on the Reykjanes Peninsula. In 1999, a major geothermal eruption destroyed a drill hole at Seltún and created a large new vent. A previous attempt at geothermal drilling in the 1970s was abandoned after local protests. The boardwalks allow close-up views of the boiling features safely.

Seltún is a truly extraordinary natural attraction located within the Krýsuvík volcanic area on the Reykjanes Peninsula, southwest Iceland. This highly active geothermal field offers visitors an immersive and visually stunning encounter with Earth's raw power. As depicted in the accompanying image, the landscape is a riot of colour, with mineral deposits painting the earth in shades of brick red, vibrant sulphur yellow, stark white, and even subtle blues. Boardwalks are thoughtfully laid out, allowing safe passage through the otherworldly terrain of boiling clay pots, audibly bubbling mud pools, and powerful fumaroles that release plumes of steam into the crisp air. The geothermal system here has been intensifying in recent years, hinting at the dynamic forces at play beneath the surface. Seltún is conveniently located just 40 minutes from Reykjavík, making it an ideal half-day trip, especially when combined with nearby attractions like Kleifarvatn lake and the scenic Reykjanes lava flow drive. It offers a geothermal experience comparable to more remote sites like Hverir at Mývatn, but without the extensive northern journey, and is rarely crowded. The iconic Blue Lagoon is also a mere 20 minutes away, making Seltún a perfect stop on a Reykjanes exploration.
