Mýrarhver — 'Marsh Spring' or 'Bog Spring' — is a geothermal hot spring in Iceland located in or near a marshy area, where the warmth of the emerging geothermal water creates a microhabitat of lush mosses, sedges, and thermophilic plants that contrast vividly with the surrounding volcanic terrain. Such wetland hot springs are ecologically distinctive, their warm margins hosting specialised communities of heat-adapted microorganisms and plants that thrive where geothermal energy and water meet. Mýrarhver offers an unusual insight into the life that flourishes at the intersection of geothermal heat and the Icelandic wetland landscape.
Insider tip — Mýrarhver — Moor Spring — emerges from boggy, thermally altered ground in the lower reaches of the Kerlingarfjöll geothermal valley where the terrain flattens toward the Kerlingará riverbed. The warm, wet substrate supports unusual thermophilic mosses and sedges that form a lush green carpet surrounding the vent. At 40°C, the outflow is among the coolest in the Ásgarður cluster and can be used for warm-water bathing on calm, windless days. The moor setting gives a quieter, less dramatic character than the high-temperature vents on the valley slopes above.
