Spiez to Interlaken by Train: A Trip on the Lake Thun Railway Line

This review covers my train journey from Spiez to Interlaken on the Lake Thun railway line, which is part of the longer Golden Pass rail route.

From Spiez to Interlaken by train

After my visit to the highly picturesque town of Spiez, it was time to continue my journey along the Golden Pass rail route from Montreux to Lucerne.

I’ve outlined the basics behind the Golden Pass in an earlier chapter, so for more information on logistics, including ticket prices and the other Swiss trains that make up this scenic rail route, make sure you read that first.

The next train ride I was scheduled to take was the short journey from Spiez to Interlaken, where I would connect to my final Golden Pass train bound for Lucerne.

Spiez station

The railway station of Spiez is located on a hill some 10 minutes away on foot from the town centre.

Before you catch your train, make sure to walk towards the balustrade along the pavement in front of the railway station to enjoy some sweeping views over Spiez and Lake Thun.

Spiez railway station has a ticket office, a restaurant, and a small convenience store.

As I was using an Interrail pass, I could take any train I wanted, so I just checked the departures screen on which platform the next train to Interlaken was set to depart.

On board the double deck train

On the standard-gauge railway line between Spiez and Interlaken Ost, there is a variety of trains you can potentially take.

Between Spiez and Interlaken, you will find Regio Express trains (RE) operated by BLS, as well as InterCity (IC) or EuroCity (EC) trains operated by the Swiss Federal Railways (SBB).

In fact, even the odd InterCity Express (ICE) train from the German Railways (Deutsche Bahn) ply this route on their long journey from Germany to Interlaken and back!

If you are flexible about which train to take, there is a train departure at least every half hour.

I was travelling from Spiez to Interlaken Ost on a Regio Express service, which was operated by one of the double deck trains of BLS.

These double deck trains have both first and second class, with an identical 2+2 seat configuration, although first class offers more comfortable seats and generally provides a quieter atmosphere.

Departure from Spiez

At just 19 kilometres distance, the stretch between Spiez and Interlaken Ost is the shortest leg of the Golden Pass rail route.

My Regio Express train takes 21 minutes to traverse this line, which is part of the Lake Thun Railway which links Thun with Spiez and Interlaken.

As the name implies, the railway line follows the shoreline of Lake Thun, and you have some magnificent lakeside views from the train when you travel from Spiez to Interlaken.

Do make sure you sit on the left-hand side of the train in the direction of travel when going from Spiez to Interlaken (or on the right-hand side when travelling in the opposite direction) as that’s where the views over the lake will be.

Almost immediately after departure from Spiez, you are already treated to some gorgeous views over Lake Thun.

Lake Thun views

On the first few kilometres, the railway line is positioned slightly higher in the hills, offering sweeping views of both the countryside, some villages, and the lake itself.

As the journey progresses, the train gradually descends towards the lakeshore, eventually running parallel to the main road directly alongside the lake.

From this point, you get an even better impression of the size of Lake Thun and the impressive mountains that surround it.

Lakeside church

One of the most picturesque bits of the Lake Thun railway line between Spiez and Interlaken lies near the village of Leissigen.

Here, you have some great view over the beautiful lakeside church of Leissigen with its Swiss-style clock tower.

Interlaken West

After a while, the railway line reaches the eastern end of Lake Thun, and shortly thereafter, it enters the outskirts of Interlaken.

All trains, whether they are Regio Express (RE), InterCity (IC), EuroCity (EC), or InterCity Express (ICE) services, make stops at both Interlaken West and Interlaken Ost stations.

Interlaken West is the more centrally located of the two railway stations in town, while Interlaken Ost is the main station and the point where you connect to onward trains towards Lucerne (Luzern).

Riding through Interlaken

The short, final stretch from Interlaken West to Interlaken Ost is certainly not boring, as the train will ride straight through Interlaken.

From the train window, you can catch sight of some of the iconic grand hotels in Interlaken, which is an important tourist centre.

On the short stretch through Interlaken, the train will also cross the River Aare twice.

The River Aare connects Lake Brienz with Lake Thun, from where it will eventually stream towards the Swiss capital of Bern and its eventual convergence with the River Rhine near the small town of Koblenz in the Swiss canton of Aargau.

Soon after the second crossing of the Aare, my regional express train pulled into the station of Interlaken Ost bang on time.

Interlaken Ost

Interlaken Ost serves as the terminus of the standard gauge Lake Thun railway line.

At Interlaken Ost, you can however change to several narrow-gauge railway lines, including the Brünig Railway, which connects Interlaken with Lucerne, and which I would be taking next.

The train journey from Spiez to Interlaken might be short, but it provides some fabulous views over Lake Thun and the surrounding mountains.

The stretch between Spiez and Interlaken forms part of the Lake Thun railway line, which connects Thun with Spiez and Interlaken.

If you travel along the scenic Golden Pass rail route, you will also partially traverse the Lake Thun railway on the stretch between Spiez and Interlaken.

Whether you are travelling on board one of the Regio Express services or an InterCity train, you will be treated to some amazing lake views.
