About Thjorsardalur Valley
Þjórsárdalur (Thjorsardalur) Valley is a historically and geologically rich area in South Iceland, carved by the Þjórsá river (Iceland's longest river). The valley contains some of Iceland's most important archaeological sites, most notably Stöng, a Viking-age farmstead buried by ash from the catastrophic Hekla eruption in 1104 AD. The site was excavated in the 1930s and a reconstruction called Þjóðveldisbærinn was built nearby, offering visitors a glimpse into medieval Icelandic life. The valley is also home to spectacular waterfalls, including Háifoss (122m, Iceland's third-highest) and the enchanting Gjáin valley with its moss-covered lava formations, streams, ponds, and multiple small waterfalls. The landscape is a mix of lush vegetation, volcanic rock, birch forest, and highland wilderness. The area serves as a gateway to the highlands and offers excellent hiking, photography, and historical exploration.
