On the rugged, windswept Reykjanes Peninsula lies a destination displaying Earth’s raw energy of bubbling mud pools, hot springs, and billowing steam. Welcome to Gunnuhver Hot Springs, a geothermal wonderland that combines natural beauty, volcanic intrigue, and Icelandic folklore into a captivating experience.

For travelers and volcano enthusiasts, Gunnuhver is more than just a stop on a scenic drive—it’s a portal into the fiery heart of Iceland.

How Gunnuhver Hot Springs Came to Be: Earth in Motion

Iceland’s location straddles the Mid-Atlantic Ridge, where the North American and Eurasian tectonic plates diverge. This unique geological position makes the area a hotspot of geothermal activity, with magma reservoirs heating underground water to create geysers, fumaroles, and hot springs.

Gunnuhver Hot Springs is part of the Reykjanes Geothermal Field, which is formed by volcanic activity beneath the surface. Rainwater and snow melt seep into the ground, where it meets superheated magma, transforming into steam and boiling water that forces its way upward. The result is a surreal landscape of bubbling mud pots, hissing steam vents, and mineral-rich pools painted in shades of white, gray, and orange by sulfur and other deposits.

The Current State: A Dynamic Landscape

2021: A new eruptive period on the Reykjanes Peninsula started with the eruption of the Fagradsjvall volcano and subsequent magmatic eruptions near Gunnuhver. Today, Gunnuhver is one of Iceland’s most active geothermal areas, constantly reshaped by the forces beneath it. New fumaroles and mud pools have appeared in recent years, while others have shifted or disappeared.

Visitors can explore the area via well-maintained walkways and viewing platforms. These paths provide safe vantage points to witness the geothermal activity up close without risking harm from scalding steam or unstable ground. The largest mud pool, a 20-meter-wide bubbling cauldron, is mesmerizing and often enveloped in dense steam clouds.

• Mud Pools: The bubbling mud is a mixture of water, clay, and volcanic minerals heated to boiling by the geothermal activity below.
• Mineral Deposits: The colorful crusts around the springs are formed by minerals like sulfur, iron, and silica, painting the landscape in earthy hues.

Practical Tips for Travelers

• Best Time to Visit: Gunnuhver Hot Springs is accessible year-round, but the steam is particularly striking on colder days when it contrasts with the crisp Icelandic air.
