In fact, this Nordic country has around 45 natural hot springs and geothermal pools for you to enjoy. We are going to cover some common questions about these natural wonders. While also sharing some of our top picks for visiting Iceland's volcanic hot springs and geothermal pools.

What are volcanic hot springs and geothermal pools?

The volcanic hot springs are natural, thanks to the volcanic activity in the area. The water is heated by geothermal energy, which comes from beneath the earth's surface.

You can usually only find geothermal pools in locations that have volcanoes currently, or a long time ago.

Why does Iceland have so many hot springs?

Iceland is a volcanic zone and it lies across the Mid-Atlantic Ridge. This is the boundary area between two tectonic plates.

The hot springs sit above areas that have strong volcanic components. These locations are commonly referred to as a "hotspot "for volcanic activity.

What are the benefits of soaking in geothermal water?

There are so many benefits of soaking in geothermal water. Thanks to the water’s natural detoxifying minerals. First off, the heat from the water can help ease achy muscles and pains. Then the minerals can detoxify your skin cells and remove toxins from your body.

You will find many athletes and hikers in hot springs after long extensive workouts. Soaking in the water can heal your muscles quicker than not.

Studies show that those with skin conditions can benefit from using geothermal water. The detoxifying components can help heal dry or rough skin.

We also think it's great for your mental health. Because let’s be honest, there is nothing more relaxing than spending your day enjoying Iceland's natural hot springs. Breathe in the fresh air while admiring the views from the volcanic pool.

How long can you sit in hot springs?

We know it's tempting to soak for hours in geothermal baths, but don’t. The best way to soak is to sit for 15 minutes at a time and then take a break. Let the cool air hit your skin to bring down your body temperature and drink plenty of water to rehydrate.

Are hot springs good for your hair?

No, hot springs in iceland can dry out your hair because of the heat and minerals. Many will keep their hair tied up and try not to get it wet.
