Hiking on Mt. Hestfjall in West-Iceland - a Visit to Andakílsá River and a dip in a Hot pool

In my last 2 travel-blogs, I have been showing you places of interest in West-Iceland. I showed you the beautiful waterfall Hvítserkur and the natural hot springs in Lundarreykjadalur among other places of interest. 

Now I am going to show you the view from Mt. Hestfjall and the waterfall in the river Andakílsá, plus a dip in Hreppslaug pool, which gets its geothermal water from a hot spring close by.

This trip was a summer day-tour with friends. I am not an avid hiker, but I joined the group for an easy hike up Mt. Hestfjall - the Horse Mountain in Borgarfjörður in West-Iceland.

Several mountains in Iceland bear this name. Mt. Hestfjall in Borgarfjörður is a 221 metres high mountain, the end of which lies between Lundarreykjadalur and Skorradalur.

I found Mt. Hestfjall to be fitting for my 3rd and last travel-blog in this series on Borgarfjörður, given that my 1st travel-blog is on Skorradalur and the 2nd one is on Lundarreykjadalur. We hiked up the eastern part of the mountain, where it is easy to hike. The northwest part of Mt. Hestfjall, on the other hand, is craggy.

Mt. Hestfjall is named after Hestur farm in the vicinity, but Hestur farm is an experimental farm on sheep herding.

We started from that farm in the north and hiked on top of the mountain with a few stops on the way. I am always glad for such stops as I can walk for hours on the even ground, but when I have to walk uphills then I am in trouble. That is why out of 250 travel-blogs I only have 1 on a mountain hike - this one ;)

It took us 1.5 hours to reach the top of Mt. Hestfjall from the farm. It is a relatively easy hike, but quite rocky.

And what a view! From here we could see the mystical Snæfellsjökull glacier by the horizon, but the Snæfellsnes peninsula is a very popular place to visit with a myriad of sights.

I also spotted the cone-like Mt. Baula, Mt. Hafnarfjall, Skarðsheiði and Skessuhorn, Hvanneyri and Borgarnes. Borgarfjörður for sure is one of the many beautiful places in Iceland. From here was also a good view of Lake Skorradalsvatn which hides a serpent called Skorradalsormur.

A part of the group ventured on the very top, amongst them my father-in-law, who is a renowned mountain goat. 

I took a video, but it, unfortunately, didn't capture the mountain view.

After spending some 35 minutes on top of Mt. Hestfjall enjoying the view, we started descending - it is a rocky path so proceed with caution. I stumbled down the mountain, far from elegantly ;) I tend to tense up on rocky terrain, still, I am always forcing myself to venture further.

Big rocks, which have fallen down from the mountain create a cluster of trolls - they are called Karlar or the Men, but such rock formations are often referred to as Karl and Kerling - meaning the Troll and the female Troll. Many a folklore has been written on the trolls in Iceland.

Our next stop was to be Andakílsá river. We hiked through Seldalur valley and headed south and a leisurely 1.5 hour's hike took us to Andakílsá river.

On the way, shortly after we had descended from Mt. Hestfjall we saw a herd of horses running eagerly towards us from the distance. We stopped as this was an unusual sight.

They came running so fast that the earth trembled. And straight towards our group! We took photos left and right as this was such a beautiful sight, all these horses with the fluffy manes fluttering in the air.

What a treat this was after having visited Mt. Hestfjall - the Horse mountain!  What the horses were after was our packed lunch ;) They sniffed in all our pockets and managed to get a bite or two.

Hestfjall in West-Iceland - a Visit to Andakílsá River and a dip in a Hot poolThe whole herd then joined our hike, they just mixed in with the group like it was the most normal thing to do. We were delighted to have this beautiful company. After a long while, they left and others joined us.

We crossed road 508 on foot, but that is the road to Skorradalur and Hvítserkur waterfall.

Andakílsá and the waterfalls

Hiking on Mt. Hestfjall in West-Iceland - a Visit to Andakílsá River and a dip in a Hot pool

In a previous travel-blog, I showed you the beautiful off the beaten track waterfall Hvítserkur which runs in the river Fitjaá and into Lake Skorradalsvatn from the east side. The rock stream Andakílsá river runs from the west side of Lake Skorradalsvatn.

In 1947 Andakílsá was harnessed with a dam (miðlunarstífla) by the reflux of Lake Skorradalsvatn. There are several waterfalls in Andakílsá river, Andakílsárfossar waterfalls, but they were just a trickle on the day of our visit, since the river is harnessed.

We checked out the intake reservoir and the dam and then hiked by the riverbed. It must have been a sight to see when the waterfalls came cascading down the river. Now only the waterworn rock remains, still very pretty. 

When ON - Orka náttúrunnar, the owners of the dam, emptied the lagoon back in 2017, the dire consequences were not foreseen. Around 10,000 thousand cubic metres of sediments and mud flooded from the intake reservoir by Andakílsvirkun into the river, filling it with abiotic mud.

It is so sad that this resulted in such an ecological disaster.

The fishing spots in this popular river were ruined and there is no saying when its biota will turn back to normal.

There was no salmon fishing in Andakílsá river in 2017 and 2018 and there will be none until 2020 if all goes well, but both small salmon and sea char could be caught in the river. Around the middle of the last century, some huge salmons were caught in Andakílsá.

After a 10 minute walk, we reached a pretty waterfall in the river, which cascaded in two separate, but equal waterfalls into a pool. Such a pretty spot.

We had been walking on the edge of the gorge and had by now reached the power plant.

A sign by the waterfall warns of not jumping in the waterfall and swimming in the pool beneath it, as the river is a salmon river. Which was not the case though when we visited because of the accident by the dam.

Andakílsá river runs from Lake Skorradalsvatn and into the mouth of the 117 km long glacial river Hvítá in Borgarfjörður before it joins the sea by Borgarfjarðarbrú bridge.

Further up Hvítá in Reykjadalur valley we find Hraunfossar waterfalls, which fall into Hvítá river and are counted amongst the most beautiful waterfalls in Iceland.

The somewhat strange name Andakíll is explained in the Saga of Egill, which tells you the story of the settlers of this area. The passage is found in the 28th chapter of the Saga of Egill.

It goes like this - in Icelandic first:

"Grími hinum háleyska gaf hann bústað fyrir sunnan Borgarfjörð, þar er kallað var á Hvanneyri; þar skammt út frá skarst inn vík ein eigi mikil; fundu þeir þar andir margar og kölluðu Andakíl, en Andakílsá, er þar féll til sjóvar. Upp frá á þeirri til þeirrar ár, er kölluð var Grímsá, þar í milli átti Grímur land."

Hiking on Mt. Hestfjall in West-Iceland - a Visit to Andakílsá River and a dip in a Hot pool

The English translation: "To Grim the Halogalander he (Skalla-Grímur Kveldúlfsson RHR) gave dwelling-place south of Borgar-firth, on the shore named Hvann-eyrr. A little beyond this a bay of no great size cuts into the land.

There they found many ducks (endur in Icelandic RHR), wherefore they called it Duck-kyle, and the river that fell into the sea there Duck-kyle-river. From this river to the river called Grims-river, the land stretching upwards between them Grim had".

The river Kíll in East-Iceland

The Icelandic word kíll does not have the same meaning as the English word kill. Kíll in Icelandic means a deep and calm stream. So now you know and won't get startled when you see the sign Kíll by a river in Iceland ;)



Hespuhúsið - the open plant dyeing studio Hiking on Mt. Hestfjall in West-Iceland - a Visit to Andakílsá River and a dip in a Hot pool

Our next stop was a visit to Hespuhúsið, which is a stone throw from the river. Hespuhúsið is an open plant dyeing studio, where the very knowledgeable Guðrún Bjarnadóttir dyes yarn in the old traditional Icelandic way from herbs in nature.

She allows visitors to look into her pots - and she showed our group the procedure in which she dyes the Icelandic wool. I love Icelandic plants and listened to her with great enthusiasm.

It was a delight listening to Guðrún - this truly is her passion. I remember her as a small girl from my elementary school - she is a triplet and the 3 sisters looked exactly the same and didn't go unnoticed in Iceland :)

She also sells her dyed yarn at the studio. You can see more photos on her website Icelandcolours.com.

You can visit her studio in the summertime from 12:00-18:00 and upon request in the wintertime if you write to her at hespa@vesturland.is.

Hespuhúsið is located at 64°32´23" N 21°41´51" W.

Hreppslaug pool Hiking on Mt. Hestfjall in West-Iceland - a Visit to Andakílsá River and a dip in a Hot pool

It was now time for some relaxation after the hike and a dip in Hreppslaug pool hit the spot. Hreppslaug is close by, but we had to cross Andakílsá river by stepping on stones and walk for a short distance to the pool.

Hreppslaug gets its geothermal water directly from hot springs next to the swimming pool. It was built in 1928 and is now preserved. It is run by the Youth Organization Íslendingur. Several hot pools in Iceland are run by youth organizations, like Brautartunga, which I showed you in my last travel-blog.

Hreppslaug is only open in the summertime, but you can visit the hot springs behind the swimming pool and take a foot-bath in the warm river.

Hreppslaug pool is located at N64° 32' 15.049" W21° 42' 8.657"

Close by you will also find Hvanneyri, a small agricultural community of around 250 people and Hvanneyri Agricultural University, which I will show you in another travel-blog. In the meantime you can check out some other travel-blogs I have written on what there is to see and do in Borgarfjörður:


Hvanneyri is at an 83 km distance from Reykjavík via Hvalfjarðargöng tunnel. It is best to rent a car in Reykjavík and explore this area on your own. Just remember that a 4x4 is needed for Hvítserkur waterfall on road F-508.

Have a lovely time in West-Iceland :)
