Seltún - the colourful Geothermal Area at Krýsuvík on the Reykjanes Peninsula in SW-Iceland

You don't have to go far from Reykjavík to see colourful geothermal areas. I have already told you about the Hengill geothermal area in a previous travel-blog,  which is only half an hour's drive from the capital city.

Another colourful geothermal area is Seltún, which is located beneath Sveifluháls, on the Reykjanes peninsula in SW-Iceland.

This interesting geothermal area has got two names; it is either called Seltúnshverir (the hot springs at Seltún) or Krýsuvíkurhverir (the hot springs at Krýsuvík). The hot springs and mud pools are right by the road, making this geothermal area very easily accessible.

Once you arrive, you can leave your car at the car park and hike up to the mountains by Seltún. I have only been as far as the upper platform of the geothermal area though. The area is relatively big with wooden paths and 2 viewing platforms from which you can get a fantastic look at the multi-coloured geothermal area.

Like all the geothermal areas in Iceland, visiting Seltùn is like stepping into another dimension. At Seltún you will see both solfataras and fumaroles, aka; bubbling mud pools and steaming hot springs. The mud pools all around you are simmering and boiling, hissing through vents in the mud.

The colours in this area range from different nuances of red, grey, brown, silver, yellow to white - all in one area! - with steam rising up in the air, adding to the mystery of this place.

There is no describing what nature offers us at geothermal areas; you just have to see it for yourself. I often take my foreign guests to Seltún as it is so close to Reykjavík, and they always love the experience. You don't have to drive long distances to see beautiful nature in Iceland.

Here you will see the vivid yellow colours of sulphur (sulphating) and all types of orange colours. Notice the details in the yellow colour in my photos - there is so much beauty in the details, and at Seltún you will get some fantastic photo opportunities.

The colours are very vivid in the sunshine, so having the privilege of living close by, I always visit this area when the sun is shining to get some good photos.

You will immediately notice the overwhelming stink of sulphur. Take care as the sulphur is poisonous, and one can get a nasty headache and nausea if too much of it is inhaled. There used to be sulphur mines here until 1880 as sulphur was a popular commodity in the 13th century and onwards. 

I added a very short video below, which I shot last year, just to give you the feeling of the serenity of this place:

But it wasn't always this serene, as an explosion took place here on this spot at Seltún on the 25th of October 1999. A large vent (43 meters in diameter) opened in the ground. It was so massive that the coffee shed by Seltún got destroyed.

Luckily nobody was around at the time of the explosion, but some workers had just left the area.

The explosion is believed to have been caused by the experimental drill hole from 1949 being clogged up by deposits. After the explosion, a pretty pond was created in beautiful geothermal settings.

Another drill hole at Seltún started spouting hot mud back in 2010.

A word of caution, step carefully here, the pathways are narrow, and when I walk over this boiling area, I always feel that if I were to slide, I would have my foot in a mud pool! The heat here is 80-100 degrees C, so let us always keep to the marked trails and pathways, and hold on to your children.

A warning sign at Seltún warns us of the danger and advises us to stay on the trails because of stream eruptions and hot springs.

In my photo above you will see a foot-step inside the closed off geothermal area! Somebody actually stepped inside the boundaries and stepped through the thin crust of earth! And into the boiling mud beneath! Exactly what I am always warning people against.

I saw footsteps all over the closed-off area... why do people do this?

My mother told me that when she was young, she saw a man accidentally stepping into a hot spring. She said that she would never forget how the skin on his foot immediately peeled off due to the immense heat of the water. So there are some real dangers here and a reason why some areas are fenced off.

We, locals, know about these dangers as we are warned about them from an early age, so respecting these areas comes as second nature to us. But when we travel abroad, we might sometimes behave silly as we don't know the dangers in other countries. So please, follow my local advice and never step inside fenced off areas.

Seltún-Krýsuvík geothermal area is only some 40 km away from the capital city. You can rent a car in Reykjavík and reach Seltún geothermal area in 40 minutes.

Fúlipollur - Foul smelling puddleSeltún - the colourful Geothermal Area at Krýsuvík on the Reykjanes Peninsula in SW-Iceland

On the east side of the road by Seltún, you will find two big mud pools. They are called Fúlipollur or "Foul smelling puddle" as they stink of sulphur. Fúlipollur looks like a bottomless pool filled with boiling brimstone. The level of mud in the pool varies and I have photos from my visit back in 2013, where there is very little mud in the pool.

I find it amazing how the grassy landscape can all of a sudden turn into a geothermal mud pool area, with two big boiling holes in the ground. 

The explosion crater Grænavatn

A short distance from Seltún geothermal area you will find the explosion crater Grænavatn - "Green Lake". The lake, which is 46 metres deep, gets this beautiful green colour from the crystals and hot spring algae in the lake. I always stop by the lake just to see what it looks like - sometimes it is green and sometimes it is blue as the colour varies from day to day.

You can now drive further on and visit all the interesting sights on the Reykjanes Peninsula. 

I have added my video of Brimketill just to give you a preview of what the Reykjanes peninsula has to offer.

You can visit this area on a guided tour or on your own. You can rent a car in Reykjavík and go on a lovely day trip with a rewarding dip in the Blue Lagoon at the end of the day.

     I will soon write a travel-blog on my 10 most favourite sights on the Reykjanes peninsula, as there is so much to see in this area.
     
    My next travel-blog though is on the haunted Gunnuhver geothermal area on the Reykjanes peninsula, where you will find Iceland's biggest mud pool.
     

    Have a lovely time on the Reykjanes peninsula :)
