Lake

Weather…

Mývatn is a shallow, nutrient-rich lake in northern Iceland, situated in an area of extreme volcanic activity. The lake was formed approximately 2,300 years ago by a massive basaltic lava eruption and covers an area of about 37 square kilometers. Its name literally translates to Midge Lake, referring to the vast swarms of midges that appear in summer, providing a vital food source for the local bird population. The region is world-renowned for its biodiversity, particularly for the wide variety of duck species that breed there. Geologically, the surroundings are extraordinary, featuring the pseudocraters at Skútustaðir, the eerie lava formations at Dimmuborgir, and the bubbling mud pots of the nearby Hverir geothermal area. The lake's average depth is only 2.5 meters, which allows the water to warm quickly and supports abundant aquatic life. Mývatn is a key stop on the Diamond Circle sightseeing route and a major hub for tourism and geothermal energy in the north.

📋 Practical info

🧭

Getting there

The lake is typically easily accessible via well-maintained main roads that encircle or run close to the shoreline. Numerous viewpoints and short walking trails can be directly reached from the primary paved routes.

📅

Best season

Summer months offer the best opportunity to observe the diverse birdlife and spirited vegetation around the water. Winter transforms the area into a quiet, frozen landscape, well-suited for seeing the northern lights under clear skies.

⛰️

Terrain & paths

The surrounding landscape features generally flat or gently rolling walking paths made of compacted dirt or boardwalks. Some sections may navigate through fascinating but uneven lava fields, requiring a moderate level of attention.

🎒

What to bring

Comfortable walking shoes are usually sufficient for the main trails, but waterproof boots are recommended for venturing near the wetland areas. In summer, insect repellent and a specialized head net are indispensable against dense midge swarms.

🅿️

Parking

Ample parking is generally available at designated visitor centers and scattered lookout points around the perimeter. These lots can fill up quickly during the peak tourist season, so arriving earlier in the day is always a good strategy.

⚠️

Safety

Stay strictly on the marked paths to protect the fragile geothermal and wetland ecosystems from permanent damage. The water temperature and depth can vary wildly, making swimming prohibited unless specifically indicated otherwise at managed baths.

⏱️

Time needed

A leisurely drive around the lake with frequent stops at major viewpoints takes around two to three hours. Nature enthusiasts should dedicate at least half a day to fully explore the diverse hiking paths and observe the local bird species in detail.
