Seltún Geothermal Area, located in Iceland's Reykjanes Peninsula, is a fascinating landscape shaped by volcanic activity and geothermal phenomena. This area is characterized by vibrant, colorful mineral deposits, steaming hot springs, and bubbling mud pots, creating a surreal and otherworldly atmosphere.

Visitors to Seltún can explore boardwalks that wind through the geothermal area, offering close-up views of the boiling mud pools and steaming vents. The distinct odor of sulfur fills the air, underscoring the area's geothermal activity and adding to its unique appeal.

The geothermal features at Seltún are a result of Iceland's location on the Mid-Atlantic Ridge, where the Eurasian and North American tectonic plates meet. This geological activity heats groundwater, causing it to rise to the surface and create the characteristic steam vents and hot springs.
