Skjaldbreiður, Shield volcano in Bláskógabyggð, Iceland
Skjaldbreiður is a shield volcano in western Iceland that rises to roughly 1060 meters and dominates the landscape with its distinctive broad, gently sloping form. A crater roughly 300 meters across sits at the summit, defining the volcano's rounded profile.
The volcano formed roughly 9500 years ago through a series of eruptions that also shaped the basin of Thingvallavatn, Iceland's largest lake. Multiple phases of lava flow over thousands of years built the mountain and reshaped the surrounding landscape.
The name Skjaldbreiður references the volcano's broad, flat shape that resembles traditional Norse warrior shields, and locals still use this comparison when describing the mountain.
Marked hiking trails make the volcano accessible during summer months, while winter visits require specialized gear and experienced guides due to harsh conditions. Sturdy footwear and layered clothing are essential year-round since weather can change rapidly.
Many visitors overlook that the volcano spans an enormous area built from separate lava units deposited at different times over thousands of years. This layered history of eruptions makes it valuable for studying how shield volcanoes grow and evolve.
