Itinerary Summary
In this itinerary, we try the things that are unique to Lake Thun.
This means visiting unique attractions like the town of Thun, Oberhofen Castle, Spiez, and either Mount Niesen or Niederhorn. If the weather does not cooperate, consider replacing Mount Niesen or Mount Niederhorn with Saint Beatus Caves, as this attraction can be enjoyed regardless of the weather.
- Visit the town of Thun because it has a castle that offers a magical view of the Bernese Oberland;
- Oberhofen Castle because of its beautiful blend of scenery and architecture;
- Spiez for its unique Mediterranean flair; and
- Mount Niesen or Niederhorn for their unique breathtaking views of the region.

Full Lake Thun Itinerary Details
Located in the heart of Switzerland, Lake Thun offers visitors several ideal starting points for their journey. The most popular jump-off locations include…
- Spiez (west of Lake Thun), which is frequented by visitors from Gstaad, Montreux, Visp, Kandersteg, Brig, or Zermatt.
- Interlaken (southern tip of Lake Thun) is another common starting point, particularly for travelers from Lucerne and the rest of the Bernese Oberland.
- Lastly, Thun (northern tip of Lake Thun) is a favorite among tourists from Bern, Basel, and Zurich.
Regardless of your origin, though, I recommend beginning your trip at the northern part of Lake Thun, and there is a couple of reasons for this.
- The tourist attractions in the northern part of the lake are conveniently close to each other. This proximity allows you to visit more places in the early part of your day without the crowds that typically gather around midday.
- Thun serves as the gateway to the Bernese Oberland. The city offers stunning panoramas of the Bernese Alps and Lake Thun, providing a visual “appetizer” for the beautiful experiences that await you later in the day.



Morning
So yes, this trip to Lake Thun begins in Thun. From this charming town, you’ll gradually uncover the beauty of Lake Thun, moving southward towards Oberhofen Castle, drawing ever closer to the even more breathtaking Bernese Alps.

Afternoon
After enjoying your lunch, you’ll be heading to Spiez, another picturesque town that boasts yet another castle. Finally, Mount Niesen, which offers a sweeping view of Lake Thun. I recommend Mount Niesen because I simply can’t think of any other place that offers such a panoramic view of Lake Thun! The view from this unique mountain could indeed be utterly spectacular.
However, depending on the season and weather, you might want to consider other attractions like Niederhorn. It’s a beautiful alternative to Mount Niesen, especially since Mount Niesen isn’t easily accessible during winter. The funicular to this mountain only operates outside of the winter season. If the weather turns completely against you, you can still make the most of the day by visiting the Saint Beatus Caves.

Author’s Note: In this one-day Lake Thun itinerary, you might want to skip Spiez Castle (since you’ve already visited Oberhofen Castle) if the schedule seems too packed. I recommend booking your tickets (for the boat, trains, and funicular) online and in advance to save time at the ticket counters. A Swiss Travel Pass and other regional day passes (see the resources section) can be really helpful in saving time and keeping to your schedule.
Also, note that the time stamps above are only estimates. Please double-check the schedules and timetables of the public transportation involved for your Lake Thun trip. Also, please expect adjustments you may apply considering the following factors:
- weather
- preventive maintenance of the facilities
- local events
- holidays
That would be all! I hope you enjoy your journey in Lake Thun. 🙂

Is One Day in Lake Thun Really Enough?
As you may have discovered throughout this Lake Thun itinerary, it’s impossible to visit every tourist attraction around Lake Thun in a single day. So, do you need an additional day in Lake Thun?
As this itinerary indicated, a single day should be enough to visit Lake Thun and see its highlights: a charming town, a fairytale-like castle, and a breathtaking mountaintop destination. However, you might want to allow more time if you’re looking for a relaxing, laid-back trip to Lake Thun. If you prefer, you could plan a two-day visit instead.
For instance, spend one whole day in Thun and visit Oberhofen Castle, then explore the rest of the Lake Thun attractions on the following day.
Take note: While it might seem tempting to spend more than one day in Lake Thun, I’m not strongly advocating for it. Particularly if your trip to Switzerland is less than a week, one day in Lake Thun is enough, and you can spend the rest of your time seeing other beautiful places in Switzerland.
In fact, you don’t have to venture outside central Switzerland to visit some. Spend a few days in Bern, which is just 30 minutes away from Thun, to see its well-architected city and its scenic city view. Alternatively, you can go to Lucerne. Two days in Lucerne is fun with a mix of nature and city adventure.
And let’s not forget about the Jungfrau Region! There’s so much to see there. I don’t know where to start! LOL. Here are my top suggestions: Aside from Lauterbrunnen, try Wengen, Murren, or Gimmelwald for the utmost idyllic alpine village experience.
Lastly, if you’re looking for ways to explore Switzerland, including Lake Thun, here are some ideas.
