Northern lights in Mývatn tonight

The north shore of Mývatn offers a flat lake surface that mirrors the aurora on calm nights, turning the water into a second sky. Volcanic pseudocraters dot the shoreline, giving textured foregrounds that are unusual even by Icelandic standards. The north shore road runs close to the water with minimal development, and the lake faces directly across open sky to the north. Reykjahlíð village is small enough that its lights have little effect beyond a few hundred metres. On still autumn nights the reflection can be as bright as the aurora itself.

Dimmuborgir is a field of black lava pillars, arches, and hollow towers formed when an ancient lava lake drained and its surface cooled unevenly. The formations rise up to 10 metres, creating dramatic silhouettes against any aurora overhead. The site has a well-signed car park and several short walking paths through the pillars. At night the formations are completely dark and the sky is Bortle 2 in all directions. The open landscape east of the pillars faces north without obstruction. Few places in Iceland offer this combination of geological foreground and accessible dark sky so close to accommodation.

Námafjall is a geothermal ridge on the eastern side of Mývatn where sulphur vents, boiling mud pools, and steam columns remain active year-round. At night the landscape glows faintly from the vent heat, with wisps of steam rising against any aurora above. The H.S. Orka car park at the ridge base is accessible and free. Walking the ridge in darkness requires care on the marked paths - the ground is unstable between the venting areas. The steaming foreground is unlike anywhere else in Iceland and the ridge position is open to the north. Bring a head torch and warm layers; the sulphur smell is strong but harmless.
