Like most places in Iceland visitors should always watch the weather and exercise caution around thermal areas. Weather changes quickly, and the onset of fog, high wind, or a severe storm can turn the best day into a survival situation. Similarly, thermal pools are often boiling hot and should be approached with caution, and the areas around thermal features are often unstable so all warnings and barriers should be observed.

Crime is not an issue in the Mývatn area, but sensible precautions should still be taken.
