Mývatn is a lake and surrounding region in North Iceland, known for its shallow waters, numerous small islands, volcanic formations, and rich birdlife. The lake covers about 37 square kilometers and is part of an internationally important wetland together with the Laxá River. The surrounding landscape was shaped by volcanic activity, creating a mixture of lava fields, craters, geothermal areas, and wetlands within a relatively compact area. Reykjahlíð serves as the main local settlement and provides accommodation, restaurants, and visitor services. Mývatn is also one of the principal stops on North Iceland’s Diamond Circle route.

The area has a long connection with farming, fishing, and life around the lake, while local folklore is closely tied to its unusual volcanic landscapes. Dimmuborgir, meaning “Dark Castles,” is a maze of lava pillars, arches, caves, and other formations associated with Icelandic stories about the Yule Lads. The Sigurgeir’s Bird Museum presents information about the region’s birdlife and natural environment. Mývatn’s name comes from the abundance of midges found around the lake, and these small insects form an important part of the local food chain, supporting fish and numerous bird species.

Mývatn’s surroundings contain some of North Iceland’s most distinctive geological sites. Skútustaðagígar consists of pseudocraters formed when hot lava flowed over wetlands, while Hverfjall is a broad explosion crater rising above the lake. At Hverir, near Námafjall, steaming fumaroles, bubbling mud pots, and mineral deposits cover the geothermal landscape. Grjótagjá is a lava cave containing a geothermal pool that is too hot for bathing, while Krafla provides access to volcanic terrain and more geothermal features. Earth Lagoon Mývatn offers a geothermal bathing experience using naturally heated water in a setting surrounded by volcanic hills.

Food around Mývatn reflects the region’s farming and freshwater environment, with lamb, dairy products, trout, Arctic char, and locally produced vegetables appearing in local cooking. Arctic char from Lake Mývatn is particularly associated with the area, while the surrounding farms supply other ingredients. Birdlife is another defining feature, with the lake and wetlands supporting a remarkable range of water and marsh birds and an unusually large variety of duck species during summer. Walking trails around the lake, Dimmuborgir, Höfði, and the Skútustaðagígar pseudocraters provide different views of the region’s interaction between water, vegetation, and volcanic geology.
