Get ready to discover the best things to do in Thun Switzerland, from conquering panoramic peaks and navigating its crystal-clear lake to mastering the local transport and packing the right gear for a safe, unforgettable adventure.
Why Thun is Your Perfect Swiss Adventure Basecamp
Think of Thun as your strategic outpost for alpine exploration. It sits right at the lower end of Lake Thun, with the iconic peaks of the Eiger, Mönch, and Jungfrau beckoning from a distance. This location offers some incredible benefits for outdoor lovers.
Unlike more tourist-dense towns, Thun provides a more relaxed, authentic atmosphere while still offering world-class access to nature. You can start your day with a coffee in a quiet old-town square and be on a mountain trail within an hour.
The connectivity here is a huge advantage. Thun’s excellent train and boat network means you can easily reach trailheads, lakeside villages, and cable car stations without needing a car. This makes it a perfect launchpad for both spontaneous day trips and well-planned expeditions.
The Vibe: Authentic & Adventure-Ready
Thun has a vibrant, lived-in feel. You’ll see locals swimming in the Aare river that flows through town—some even “surf” the river wave on dedicated boards. It’s a place where outdoor life is woven into the daily fabric, not just put on for visitors.
This creates a grounded, inspiring environment for any traveler looking to go beyond the surface. It’s less about ticking boxes and more about experiencing the Swiss outdoor lifestyle firsthand.
Mastering the Lake: Your Guide to Lake Thun Activities
The heart of the region is the stunning, deep-blue Lake Thun (Thunersee). Its shores are dotted with charming villages and historic castles, all set against a dramatic mountain backdrop. Getting out on the water is non-negotiable.
Paddling and Kayaking Adventures
One of the best ways to experience the lake is from water level. Renting a kayak or a stand-up paddleboard (SUP) gives you the freedom to explore hidden coves and beaches at your own pace. Several rental shops are available in Thun and other lakeside towns.
For a classic trip, paddle from the marina in Thun towards the picturesque Schadau Park. This offers incredible views of the castle and the Alps. Always check the weather forecast before heading out; the wind can pick up suddenly on alpine lakes. Wear a personal flotation device (PFD), even if you are a strong swimmer.
Classic Lake Cruises
For a more relaxed perspective, hop on one of the historic paddle steamers that crisscross the lake. This is a fantastic way to appreciate the scale of the landscape and access other key spots like the St. Beatus Caves or the town of Interlaken at the other end of the lake.
Pro Tip: A Swiss Travel Pass or a Regional Pass Berner Oberland often covers these boat trips, making it a cost-effective way to travel and sightsee simultaneously. It’s a great option for a “rest day” that still feels like an adventure.
Explore History and Views: Thun Castle and Old Town
Before you hit the high trails, take some time to explore the town itself. Thun’s Old Town (Altstadt) is a beautifully preserved piece of history, and its castle is the town’s unmissable icon.
Climbing to Thun Castle (Schloss Thun)
The imposing 12th-century castle towers over the town from its rocky perch. The walk up through the charming streets is part of the experience. Inside, you’ll find a historical museum, but the real prize is the view from the corner towers.
From the top, you get a 360-degree panorama of the town, the Aare River, Lake Thun, and the surrounding peaks. It’s the perfect spot to get your bearings and plan which mountain you want to climb next. This is one of the essential things to do in Thun Switzerland for context and perspective.
Wandering the Old Town and its Bridges
Thun’s Old Town is unique for its raised “high-level pavements.” You can stroll along the upper level of shops, then drop down to the river level. It’s a charming and photogenic area to explore.
Don’t miss the Obere Schleuse, a covered wooden bridge from the 18th century that controls the flow of the Aare River. In the summer, you can watch the famous “Aare surfers” ride the standing wave created by the dam. It’s a testament to the town’s adventurous spirit.
Your Hiking and Mountain Guide: Best Trails Near Thun
Now for the main event. Thun is your gateway to some of the most rewarding hikes in Switzerland, ranging from gentle lakeside strolls to challenging alpine ascents. Always pack the essentials, even for short hikes: water, snacks, a rain jacket like the Patagonia Torrentshell 3L, and a map or GPS app like Komoot.
The Niederhorn: The Ultimate Panoramic View
For a truly epic view over Lake Thun and the high Alps, head to the Niederhorn. You can take a bus from Thun to Beatenbucht, then a funicular and a cable car up to the summit at 1,963 meters (6,440 ft).
From the top, you can tackle the stunning ridge trail towards Gemmenalphorn. This trail offers constant, jaw-dropping views but does have some exposed sections. Ensure you have sturdy hiking boots with good grip, like the Salomon X Ultra 4, and are comfortable with heights. This is a must-do for any serious hiker.
The Stockhorn: A Westward Perspective
On the other side of the lake, the Stockhorn offers a different but equally breathtaking view. A cable car from Erlenbach im Simmental takes you near the summit. From here, you can walk through a tunnel to the panoramic viewing platform suspended over the north face.
There are numerous hiking trails leading down from the mid-station, allowing you to make a full day of it. The hike to the pristine mountain lakes of Oberstockensee and Hinterstockensee is a beautiful and rewarding option.
Niesen: The Swiss Pyramid
You can’t miss the pyramid-shaped peak of Niesen (2,362 m / 7,749 ft) that dominates the skyline. A vintage funicular, one of the longest in the world, climbs its steep flank. Or, for the truly ambitious, you can hike the trail that follows the tracks.
The view from the top is legendary, offering a complete overview of the Bernese Alps. It’s a fantastic spot for sunrise or sunset if you plan your trip with the funicular schedule.
Essential Things to do in Thun Switzerland: A Practical Guide
Knowing how to navigate the region is key to a successful trip. This practical guide covers transport, timing, and how to avoid some common problems with planning your adventure.
Getting Around: Transport Tips
Switzerland’s public transport system is a marvel of efficiency. The SBB Mobile app is your best friend for checking train, bus, and boat schedules in real-time.
- Regional Pass Berner Oberland: If you plan on using multiple cable cars and boats, this pass can offer significant savings. Do the math based on your itinerary to see if it’s worth it.
- Buses (PostBus): Yellow PostBuses are essential for reaching trailheads that aren’t on the train line. They are reliable and run on a tight schedule.
- Boats: The lake steamers are both transport and an activity. Use them to hop between lakeside villages like Spiez or Merligen to start different hikes.
When to Visit
The best time for hiking and water sports is from June to September. The weather is warmest, and most high-altitude trails are free of snow. However, this is also the busiest season.
For fewer crowds and beautiful colors, consider the shoulder seasons of late May or early October. Just be prepared for more unpredictable weather and check that high-elevation cable cars are still running. Pack layers, including a fleece and a waterproof shell, no matter the season.
Sustainable Travel in Thun: Best Practices for Eco-Friendly Adventures
Part of being a responsible outdoor enthusiast is protecting the incredible environments we visit. A sustainable approach to the things to do in Thun Switzerland ensures this beautiful region remains pristine for generations.
This is your eco-friendly care guide for the Bernese Oberland. Following these best practices is simple and has a huge impact.
- Leave No Trace: This is the golden rule. Pack out everything you pack in, including food scraps like apple cores or banana peels. They take a long time to decompose in alpine environments.
- Stick to the Trails: Marked trails are there to protect fragile alpine meadows from erosion. Cutting switchbacks or wandering off-trail can cause lasting damage.
- Use Public Transport: Take advantage of the fantastic train, bus, and boat network. It’s efficient and drastically reduces your carbon footprint compared to driving.
- Support Local: Eat at locally-owned restaurants, shop at the farmer’s market in Thun, and stay in smaller, family-run guesthouses. This keeps your money in the community.
- Respect Wildlife: Observe animals from a distance. Never feed them, as it can make them dependent on humans and aggressive.
