About

Laugahraun is an extensive lava field located in the Landmannalaugar area of Iceland's southern Highlands. The lava field was formed during an eruption around 1477 AD from the Veiðivötn-Bárðarbunga volcanic system. It covers approximately 20–25 km² and is characterized by dark, rugged aa-type lava. The lava field is notable for its high obsidian content. Obsidian is volcanic glass formed when lava cools extremely rapidly, preventing crystal formation. Large patches of glassy black obsidian are scattered throughout Laugahraun, making it one of Iceland's primary obsidian sources. Early Icelanders used obsidian from here to make cutting tools. Laugahraun forms the floor of the Landmannalaugar valley and provides dramatic contrast to the colorful rhyolite mountains (Brennisteinsalda, Suðurnámur) that surround it. The lava field is crossed by multiple hiking trails, including sections of the Laugavegur route. Vegetation is sparse on the lava field, though mosses, lichens and small Arctic plants grow in sheltered areas. The rough, broken surface makes cross-country travel difficult — most visitors stick to marked trails. The name 'Laugahraun' means 'Hot Spring Lava,' referring to the geothermal springs that emerge through cracks in the lava field, including the famous bathing pools at Landmannalaugar campsite.

📖 Story

Laugahraun erupted from the volcanic fissures beneath Landmannalaugar around 1477 AD — relatively recent in geological terms. The lava flow spread across the valley floor, burying older landscapes and creating the black, jagged terrain that surrounds the hot springs and campsite today. What makes Laugahraun special is its high obsidian content. This black volcanic glass forms when lava cools so rapidly that crystals don't have time to form. Walking across Laugahraun means crunching over fields of glassy black rock that glitters in the sunlight. Iceland's early settlers prized obsidian for making sharp tools and weapons — the lava field was a valuable resource.
