Hot springs are not just an attraction in Iceland — they are part of daily life, culture, and the country’s identity. Whether you want an adventurous soak surrounded by mountains or a high-end spa ritual overlooking the Atlantic Ocean, Iceland has something unforgettable waiting.
In this complete guide, we’ll explore:
- Why Iceland has so many hot springs

- The best hot springs by region
- Essential etiquette and safety tips
- What to pack and when to go
Let’s dive into Iceland’s geothermal paradise.
Why Iceland Has So Many Hot Springs
Iceland is one of the most geothermal-active countries in the world.
The reason is simple: Iceland sits directly on the Mid-Atlantic Ridge, where two tectonic plates meet:
- The North American Plate
- The Eurasian Plate
This creates intense underground volcanic heat. Rain and glacier meltwater seep into the earth, warm up naturally, and return to the surface as geothermal springs.
That’s why Iceland has:
- Hot springs
- Geysers
- Steam vents
- Natural warm rivers
- Heated sidewalks in Reykjavik
Hot water is everywhere — and Icelanders have embraced it for centuries.
