Reykjanes

Reykjanes, commonly referred to as the Reykjanes Peninsula, is a volcanic and seismic region in southwestern Iceland. It projects into the Atlantic Ocean and lies southwest of the capital area, forming part of the boundary between the North American and Eurasian tectonic plates at the western end of the Mid-Atlantic Ridge.

The landscape is dominated by lava fields, volcanic cones, geothermal areas, and rugged coastlines. Notable geothermal regions include Krýsuvík and Gunnuhver, with the Svartsengi field powering the Blue Lagoon. The area has a history of volcanic activity, including the Fagradalsfjall eruption that began in March 2021 along the Reykjanes volcanic system.

Human presence centers on Keflavík, Grindavík, and other settlements on the peninsula. Keflavík International Airport, Iceland’s largest airport, lies on the peninsula and serves as a major gateway for international traffic.

Economy and tourism are supported by geothermal energy production, fishing, and growing geotourism. Attractions include the Blue Lagoon spa, lava fields, coastline scenery, and accessible hiking routes across volcanic terrain. The region is characterized by a maritime climate with mild winters and cool summers, influenced by the Gulf Stream.

Reykjanes remains a focal point for seismic and volcanic monitoring in Iceland, with ongoing research and occasional eruptive activity affecting the landscape and visitation.
