Hot Springs and Geothermal Pools in Iceland
Last updated: February 5, 2026
Iceland Geothermal Wonders
Iceland sits on the Mid Atlantic Ridge where tectonic plates meet, creating abundant geothermal activity. This means hot water bubbles up naturally across the country.
Bathing in hot springs is deeply ingrained in Icelandic culture and has been practiced for over a thousand years.
Types of Hot Springs
Developed Spas
Facilities like Blue Lagoon and Sky Lagoon offer luxurious experiences with changing rooms, restaurants, and treatments.
Natural Hot Pots
Wild hot springs in natural settings, some well known and others hidden gems discovered by exploration.
Municipal Pools
Every town has a public swimming pool with hot tubs. These are where locals socialize and are wonderful cultural experiences.
Famous Hot Springs

Iceland most famous geothermal spa. The milky blue water is rich in silica and minerals. Book well in advance as it sells out.

Bathing Etiquette
Showering naked before entering pools is mandatory in Iceland. This is for hygiene and is the cultural norm.
Be quiet and respectful in hot tubs. Icelanders use them for relaxation and quiet conversation.
At natural hot springs, leave no trace. Pack out everything you bring in.
Safety Tips
Test water temperature before entering natural hot springs. Some can be dangerously hot.
Never bathe in hot springs near active geothermal areas with boiling mud or steam.
Stay hydrated. Hot water causes sweating even when you do not notice it.
