Bex Salt Mines

Bex Salt Mines

The Bex Salt Mines (Mines de Sel Bex) in Switzerland are a living museum of the salt mining industry which has operated here since the 17th century up until present day.

Visitors to the Bex Salt Mines can discover the story of this site, from the time salt was first discovered in the 15th century to how it was mined from 1684 onwards, right up until today. There is even the opportunity to descend into the depths of the Bex Salt Mines via a real mining train.

Bex Salt Mines history

Between 200 to 600 million years ago, the Rhône Valley was a shallow sea, and it is from this sea that the great salt deposits of Bex within the Canton of Vaud originate. The salt mines were not discovered until 1554 in Switzerland, and production of salt quickly followed with a salt works built in Roche. Initially run by foreign nobles, in 1685 the mines came under control of the Bernese state.

As the mines demanded large amounts of wood, in 1695 a forest was planted in the Joux Verte gorge. The trees and their natural evaporation was replaced with boiling in the 17th century to speed salt production. As demand grew, tunnels were dug to find new sources, which included deposits at Le Bévieux and Les Devens.

Bex Salt Mines today

Today, you can descend the well-lit staircase within the immense cavernous dark of the Bex Salt Mines. This working salt mine produces 30,000 tons of salt per year, and is comprised of a labyrinth of tunnels over 50 km long. When visiting the museum and mines, visitors can learn about the various techniques of salt mining that date back to 1684.

A small yellow subterranean train takes you through the mining complex to a restaurant 400 metres down. Tour are guided in French, so be sure to pick up an audioguide if you do not speak the language. For those brave enough, take an adventure tour into the original 17th century mines.

Getting to the Bex Salt Mines

If you are happy to hike, from the Bex CFF railway station to the Salt Mines it takes about 1 hour and 25 minutes. From the Bévieux TPC railway station to the Salt Mines, about 50 minutes. By car follow the A9 exit at Bex, then follow the brown road signs with “Mines de Sel” written on. Be aware not to confuse it with the Saline de Bex located just a few kilometres away.

Salt Mines at Bex Switzerland

Staying in Les Diablerets we went from seeing sky high attractions one day at the Peak Walk and Glacier 3000, to literally going underground the next! We went underground to visit the Salt mines of Bex and it is a really interesting place to visit for all the family. The Bex Salt mines have been in operation for nearly 350 years, and what’s more they are still used to mine salt to this day.

Back in years gone by, salt was a very expensive commodity in Switzerland. Known as “white gold” it was extremely precious and had to imported into the country from abroad at great cost. That was until salt was discovered in the area around Bex, something which had a profound effect on the region and far beyond.

Today you can visit the mines and learn all about the story of salt at Bex. Tours are set at certain times throughout the day and you can book the slot which is most convenient online. The tour is conducted in French but when you arrive you are given an audio device so that you can listen to everything in English or several other languages.

First of all you are taken to a large auditorium where the guide gives an introduction and you watch a film explaining the history of the mines the explaining how they had all been built by hand. There are exhibition pieces in the auditorium including the guest book in which one of the most famous visitors, Alexandre Dumas, has signed his name.

Next you’re taken on a fun little train ride in a really small train which takes you deep into the centre of the mine where you get off and continue your journey on foot.

There are lots of tunnels and galleries to explore and at regular intervals there is a number marked on a sign which corresponds to an audio commentary in your guide – so the tour is entirely self-paced.

The interior of the mine is a huge labyrinth of underground tunnels, stairways and shafts and is very impressive to see.

There is lots of equipment on display as well as information on the different techniques used to mine salt over the years at the exhibition inside the Mines.

The exhibition explores the mining of salt and its use both domestically and industrially over the years.

You can also see how the salt crystals form on the walls.

It took us just over two hours to go round and was really interesting. One of the highlights for me was seeing the demonstration of salt being harvested from the water and the special sieve type machine which enables the salt to be formed into varying sizes for different uses.

There is even some Bex wine which has its own corner in the mines where it is left to mature.

It’s an interesting place to visit and an ideal rainy day destination for all the family. At the end of the tour you can even get to try your hand at mining yourself – something that was very popular with the children in our group! You then take the little train back to the main building where there is a gift shop which sells everything from different types of salt to jars of salted caramel and salt lamps.

We were visiting in Winter and were quite well wrapped up, but please note that if you are visiting in Summer the temperature is the same as it is always around 18 degrees – so do take a jacket or sweater in case you feel cold.

Salt Mines of the Alps

Visitors to Bex, 20 km south of Montreux, are able to see Switzerland’s only working salt mine as well as extensive displays illustrating the history of the salt industry in the region. In the 17th century invaders from the canton of Berne began to produce salt at Bex by evaporating brine, and mining on a large scale began in the 1680s. A new company, Les Mines et Salines de Bex was established in 1867 to co-ordinate production in the face of competition from newly-opened saltworks in other parts of Switzerland. Ten years later the company began to produce salt by thermocompression, that is by bringing salt to the boil and compressing the resultant steam, a method that has been copied in many countries.

About 50 km of tunnels from old workings remain in the mountains. Visitors are taken into the mine on a small train and are able to see an audio-visual presentation on the history of the workings in a round chamber that was excavated in 1826 to serve as a reservoir. The conservation of the mines is supported by a voluntary organisation, L’Association pour la mise en valeur des Mines de Sel de Bex, established in 1982.

Between 200 to 60 million years ago, the present Rhône Valley was a shallow sea.The salt deposits of Bex in the Canton of Vaud are derived from the salt of this sea. A labyrinth of passages and tunnels, over 50 kilometers long, today yields 30,000 tons of salt per year.

On a visit to the museum and the mine, visitors see the various techniques of salt mining from the year 1684 to the present and the history of this white gold. A small mine train takes visitors into the subterranean world and to the restaurant located in the mountain at a depth of 400 meters.The mines can be explored further on foot. Unusual adventure tours offer treks into the mines and tunnels that date from the 17th century.

A variety of plain and herbal salts from Bex can be purchased under the brand name &ldquoSel des Alpes&rdquo.

Going underground – Touring Switzerland’s oldest salt mine

There is a reason why the Swiss excel at digging tunnels: they have been doing it for a very long time. In 1680, tunnels were dug into the Vaud Alps near Bex to get at salt buried there more than 200 million years earlier, le Sel des Alpes.

According to legend, a young shepherd noticed his goats preferred to drink water from particular springs. Tasting the water, he found it was salty. Later, in 1475, Bernese invaders boiled this salty water in large pots to extract the salt. But, by 1680, the salty springs were drying up. That’s when the digging started.

Back then digging was slow and labourious. It took two men a month to dig one metre. Today there is a labyrinthe of 50,000 metres of hand-dug underground tunnels, wells and galleries connected by trains, paths and stairways.

The tour starts with a short film in a large underground cavern. A multilingual guide with a knowledge of salt as deep as the mine itself then whisks visitors through more tunnels and galleries to a waiting underground train.

Once onboard, the train heads straight into the mountain. Far from any mobile phone signal, with overhead rock up to 800 metres deep in places, you get a real sense of how deep under the mountains you are.

There is a choice of enclosed or outdoor train seats. Riding al fresco lets you feel the breeze and take in the underground smells of salt, sulfur and other underground odours.

At times it feels like you might be on a fun park ride, except this is real! Weaving through the low tunnels gives a sense of how hard life was for the miners, working on their knees unable to stand up. These were tough times requiring a level of determination and tolerance for discomfort hard to imagine today.

After eight minutes the train arrives at its end stop, deep underground. A short walk from the train brings you to a large open cavern. Here the guide explains the surprisingly interesting history of salt.

Hundreds of years ago salt, or “white gold”, was a highly precious commodity. Like the spice trade, the salt trade made a huge mark on politics and business. It also claimed many lives.

Hollowed out logs, an early form of ventilation

The Bex mine is still fully operational. Water, now injected into the rocks, comes out with 30% salt in it. It’s then heated to remove the salt. Salt concentrations at Bex are some of the lowest in the world, and the operation is only made economically viable by an onsite hydro electric plant which makes the plant energy self-sufficient.

Switzerland has only three salt extraction facilities. One in Bex and two (Riburg and Schweizerhalle) near Basel, where salt was used as a key ingredient in the early dyes and pharmaceuticals produced nearby. Roche and Novartis might not exist without Swiss salt!

Together these Swiss salt producers extract around 600,000 tonnes of salt annually, most of which is used on icy roads and by industry. Only a small percentage ends up in food.

The tour also includes interactive sections. Visitors can try their hand at chipping off a souvenir rock fragment, hollowing out a larch log – once used to ventilate tunnels, and tasting food made with the end product Fleur des Alpes.

There is also a live display showing the old method of salt production – shown below. This method is still used to produce special salt products.

Guides are able to answer questions in a wide array of languages. The one accompanying us knew when iodide was added (1923) to Swiss table salt to prevent goitre, and fluoride (1972), to prevent dental cavities.

Our guide reckons there is plenty of salt left in this corner of the Swiss Alps: probably enough to keep the mine busy for another 200 years.

The tour takes around 1 hour and 45 minutes but feels shorter. The mine is a 45 minute drive from Lausanne and 1 hour 30 minutes from Geneva.

The site is well ventilated and a constant 18 degrees celsius year round. The company recommends booking in advance.

Bex Salt Mines - History

Company: Saline de Bex SA

Region: Vaud, Switzerland

Web address:

Fleur des Alpes is a unique product, hand harvested in the very heart of the Bex Salt Mines, Switzerland, according to an authentic manufacturing process.

Naturally rich in minerals and trace elements, Fleur des Alpes is a culinary jewel, without any additives. Its pure crystals make it an ideal finishing salt. Tradition, craftsmanship, know-how, Fleur des Alpes is an authentic local product.

An artisanal process to preserve the crystals In the heart of the Bex Salt Mines, in the Fleur des Alpes production workshop, the salt-laden water is conveyed to evaporation vats. Fragile crystals form on the surface of the water and gradually settle at the bottom of the basins. These flowers are then delicately harvested by hand and placed on larch wood draining boards for gentle drying. The Fleur des Alpes is then sieved and packaged with the utmost care, still in the workshop of the Bex Salt Mines.

FLEUR DES ALPES - LARCH EDITION This edition of Fleur des Alpes is a homage to larch wood. Thanks to its innumerous qualities, this wood has always been used in salt mines. Today, our Fleur des Alpes is still slowly and carefully dried on larch wood. In its elegant jar, Fleur des Alpes will adorn your table and reveal all the flavors of your dishes.

Bex Salt Mines

While in Switzerland, we stayed in Leysin. It’s a few kilometres away from the wonderful lake-side town of Montreux. I managed to spend a few hours at the famous salt mine on a guided tour. I would recommend this – I have never been inside a mine before. After reading about this mine in a pamphlet, I was quite intrigued because it rather reminded me of the town of Bonk and the famous fat mines in Terry Pratchett’s Discworld……

You start off by getting there on time for the timed entrances, because you will need a tour guide for the mines (so you don’t get lost in there!) You can look for available times here on their website, and I would recommend you to book in advance, so you’d know when to get there.

We started off with a video presentation, and the guide will take you around the mines and will describe the sections to you as you get there. But to get below, you will take an underground train! Look below for some pictures (I am not giving away everything!) and look out for the GIF file of the train ride back to the surface.

You can see the salt at the edge of the rock wall here in the video presentation room. A map of the sections of the mine A visitor’s logbook signed by Alexander Dumas Walkway around the mines A little fountain and you can see the salt! Ammonite fossils found in the mine A restaurant in the mine! The train, at the end of the guided tour, at the back of the restaurant The train, outside. The GIF of (a part) my train ride to the surface in the salt mine!

While waiting for our allotted slot for the guided tour, we had a nice lunch at the nearby Auberge (Inn). Walking distance from the Bex Salt Mine visitor centre.The owner is a wonderful, bubbly man. And he gave me a bottle of white wine (as we gave him a RM10 note for his restaurant currency wall).

Salt was mined in Switzerland 450 years ago. With the founding of the United Swiss Rhine Saltworks in 1909, however, a new chapter began. The foundation stone was laid 111 years ago for today's solidarity-based salt supply in all Swiss cantons and the Principality of Liechtenstein.

Swiss Saltworks can now look back on a history spanning more than 450 years – that’s how long salt has been extracted in Switzerland! Embark on a journey through the various eras of salt extraction, and discover the milestones in our company’s history.

Swiss Saltworks on the Rhine AG and Saline de Bex SA merged to form Schweizer Salinen AG.

The inauguration ceremony for Saldome2 took place. This is the largest wooden dome structure in Europe, with a capacity of some 100,000 tonnes of loose salt.

The Salt Shop at the Schweizerhalle saltworks was opened.

Start of building work on the large storage hall for de-icing salt in Riburg. The Saldome is a spectacular wooden dome structure that can store 70,000 tonnes of salt. At the same time, the high-bay storage facility went into operation at Schweizerhalle and the starting shot for the construction of the production building was fired.

A start was made on the complete refurbishment of the final production, forwarding and storage departments at the Schweizerhalle saltworks.
The company changed its name and was known from now on as Saline de Bex SA.

A record year, with the heaviest snowfall of the century in February. The two saltworks together produced the record-breaking quality of 505,000 tonnes of salt. The quality management system at VSR was certified compliant with ISO standard 9001.

The Riburg saltworks celebrated its 150th anniversary. A striking mural was added to the silo tower at Riburg.
