Natural Hot Spring
Kúalaug
South Iceland
Kúalaug is a pair of intimate, natural geothermal hot spring pools nestled amidst lush green and golden grasses in South Iceland. Located just 2 km from Geysir, it offers a tranquil escape, reflecting the sky in its warm, inviting waters.
A quiet, undeveloped natural hot pool just minutes from Geysir, for travelers happy to trade facilities for authenticity.
Story
Just a couple of kilometres from the crowds at Geysir, Kúalaug is easy to miss — two small natural pools tucked into a patch of grass beside the road in the Haukadalur area, barely announced by a low ring of stones around the smaller one. There is no car park sign or ticket booth, just warm water rising through the ground and pooling among the grasses, with the wide skies of South Iceland reflected on its surface. It's a rustic, unmanicured spot — the pool floor is soft with mud and a little algae, and the temperature shifts depending on exactly where you sit, hotter near where the spring feeds in. Because it has no infrastructure at all, Kúalaug asks for a bit of care from visitors: no changing rooms, no barriers, just a fragile patch of ground that is easy to damage if people aren't careful where they step.
History
No documented founding history exists for Kúalaug. Like many small geothermal pools scattered across the Haukadalur/Geysir area, it appears to be a naturally occurring spring rather than a built or dated attraction.
Did You Know?
Kúalaug's water temperature isn't uniform — it runs hotter, up to around 43°C (109°F), near where the spring surfaces, and cooler toward the pool's edges, so bathers shift position to find their comfortable spot.
