Iceland has a lot of glaciers and volcanoes. They are in different parts of Iceland, mostly in the south and in the highlands.

There are more than 130 volcanoes in the world, some of them active and some of them dormant.

Dormant means that they are not currently active but could become active again in the future.

What to expect to see inside volcano Iceland?

What else you can find inside the volcano in Iceland if not boiling lava and hot magma?!

Well, have you ever thought that inside the crater you can find a beautiful lake with boiling water?!

Yes, it is possible. Iceland has many crater lakes spread out across the country.

The most famous one is the Kerid crater.

The story of the Kerid crater

The crater lake from Kerid is more than 3,000 years old. Its depth is between 7 and 14 meters.

The depth depends on the amount of rain that falls and other factors.

The water is a beautiful blue color. You can get to it after hiking through lava fields.

The crater is huge! It is 170 meters wide, 55 meters deep, and 270 meters in circumference.

The lake is famous all across the country for being located in one of the best-preserved calderas in the world.

The crater can be reached by car until you get to a certain point.

After that, you have to hike the rest of the way on foot and go down into the volcano in Iceland.

This is a rare opportunity to go inside the volcano in Iceland without being worried that the hot magma will come to the surface without any warning.

A great way to explore the whole area not just the Kerid crater is with Reykjavik: Golden Circle Full-Day Tour with Kerid Crater a full tour of the most emblematic road from Iceland, Golden Circle plus a stop at the unique Kerid Crater.

The tour lasts for around 8 hours. This is enough time to visit Kerid Crater, Gullfoss waterfall, Geysir area, and Thingvellir National Park.

At the Geysir area, you will have a longer stop for lunch, but you will need to pay for your own food.

Interesting facts about Kerid crater

What is interesting about Kerid crater lake is how it was formed.

If most of the calderas appear after a volcanic explosion, scientists think that Kerid was different.

Scientists think that the place where the lake is today was a volcano.

The magma inside the volcano ran out and the lava chamber fell down.

The lake is most beautiful during the summertime when the ice melts and reveals a rainbow of colors.

Even though the lake is frozen in winter and everything is covered with snow, it doesn’t mean that the place is less beautiful.

The crater is believed to be quite young, having around 3,000 years old, and appeared when the magma chamber collapse.

This is a natural volcanic crater lake. Many people say it is one of the most beautiful crater lakes in the world.

Descending inside a volcano

I find the idea of going inside a volcano Iceland really interesting and exciting.

So I searched for an experience that would allow me to get closer to a magma chamber.

You can get very close to a volcano and go down inside of it if you include a tour to Thrihnukagigur Volcano in your plans.

This is an amazing experience that I recommend everyone tries at least once in their lifetime.

Thrihnukagigur Volcano experience

The volcano is located on your way to Golden Circle, one of the most popular attractions from Iceland.

The meeting point for hiking the dormant volcano is at Blue Mountain Cabin.

It is located right at the bottom of the ski lifts that go up on the mountain.

This unique journey to the center of the Earth is split into two parts:

  • The 3.2 kilometers hike to the Base Camp, located right near the crater
  • The descending to the crater

The Base Camp is located in the middle of nature, far from any noise or pollution.

From here, you can start your hike to the volcano.

The area is simply breathtaking, and you will be fascinated by the landscape and the beautiful scenery.

From this point, you are not allowed to go to the volcano without an experienced guide.

You can only go with a group, and there are specific times that you have to leave.

At the Base Camp, while you wait for your turn to get into the volcano, you can drink something, eat a snack and equip for the second part of the trip.

Before going into the volcano, you will receive a short training.

You will learn what to expect to find inside, how to act, and what you are allowed to do while inside.

It will take you about 30 minutes to hike from Base Camp to the edge of the crater.

Once you get there, you will start going down into the lava cave.

Exploring the volcano

The descend into the volcano is an amazing experience, and you don’t have to worry about any signs of volcanic eruption.

The trail to the crater is very well maintained and covered by wooden pols that are connected with ropes so it is a quite easy 30 minutes hike.

The descent into the crater is possible using an elevator that actually looks like a cage that is hanged from the ceiling.

Iceland Volcano Eruption

What is interesting about this volcano is that its magma chamber did not collapse during the eruption, and it can be seen intact even today.

You will descend 120 meters with this unique elevator and inside the elevator easily fit 6 people.

Although the descending last for a few minutes, your body will be flooded by adrenaline and the feeling is something you definitely have to try at least once in your lifetime.

The magma chamber from below has different colors, mostly brown, ochre, and hues of maroon and you will spend about 40 minutes inside the volcano.

Nobody knows for sure why this magma chambre is empty and some scientists consider that this is a fake lava chambre and the real one is hidden below.

What I can tell you for sure is that this volcanic landscape full of basalt rocks and mineral deposits is one of the most beautiful and unique landscapes I have ever seen.
