1. Musée Fort de Chillon – A Hidden Underground Fortress on Lake Geneva
Hidden Gem – Included with Swiss Travel Pass
Often overshadowed by its famous neighbour, the Musée Fort de Chillon is one of Switzerland's best-kept secrets — and one of the most rewarding free attractions included with the Swiss Travel Pass. Carved directly into the rock beneath Chillon Castle at the beginning of the 20th century, this authentic underground military fortress offers a completely unique experience that history lovers and adventure seekers won't find anywhere else.
Visitors can explore stone-cut tunnels, discover original military equipment from the World War era, and soak in an atmosphere that is simultaneously eerie and captivating. Guided tours are available to bring the history to life. Located on the shores of Lake Geneva between Montreux and Villeneuve, the fort is easily accessible by train — a major advantage for Swiss Travel Pass holders travelling without a car.
Whether you're combining it with a visit to Chillon Castle next door or making it a standalone discovery, the Musée Fort de Chillon is an unmissable stop on any Swiss Travel Pass itinerary along the Riviera Vaudoise.
2. Chillon Castle – Switzerland's Most Visited Historic Monument
Included with Swiss Travel Pass
Perched on a rocky island jutting into Lake Geneva, Chillon Castle is Switzerland's most visited historic monument — and a landmark that has inspired writers, painters, and travellers for centuries. Lord Byron immortalised it in his 1816 poem 'The Prisoner of Chillon', and it's easy to see why: the castle's dramatic silhouette reflected in the lake is one of the most iconic images in all of Switzerland.
Inside, visitors explore over a thousand years of history across 25 rooms, four great halls, three courtyards, and numerous towers. From medieval dungeons and Gothic chapels to frescoed great halls and breathtaking lake views, Chillon offers an immersive journey through time. Entry is fully covered by the Swiss Travel Pass, making it one of the most popular free museums in Switzerland for international visitors.
3. Olympic Museum, Lausanne – The World Capital of Sport
Included with Swiss Travel Pass
Lausanne is the world capital of the Olympic Movement, and the Olympic Museum is its crown jewel. Situated in a stunning park overlooking Lake Geneva, this state-of-the-art museum tells the story of the Olympic Games from their ancient origins in Greece to the most recent editions. Interactive exhibitions, rare artefacts, iconic sporting memorabilia, and immersive multimedia installations make this one of the most engaging Swiss Travel Pass free museums.
Sport enthusiasts and families alike will be captivated by the stories of legendary athletes, the thrill of record-breaking moments, and the universal values of the Olympic spirit. With the Swiss Travel Pass, admission is free — and the park surrounding the museum is itself worth a visit, dotted with sculptures and offering spectacular views of the Alps and the lake.

5. Ballenberg Swiss Open Air Museum – A Living Village Through the Ages
Included with Swiss Travel Pass
Spread across 66 hectares of rolling countryside near Brienz in the Bernese Oberland, the Ballenberg Swiss Open Air Museum is like stepping into a living, breathing time capsule. Over 100 authentic historic buildings — farmhouses, mills, barns, and workshops — have been transported from across Switzerland and meticulously reconstructed here, creating an extraordinary open-air village that spans centuries of Swiss rural life.
Costumed craftspeople demonstrate traditional skills such as cheese-making, weaving, blacksmithing, and lace-making. Animals roam freely between the buildings, and seasonal events bring the site to life throughout the year. A full visit can easily take an entire day — and it's fully included with the Swiss Travel Pass. One of the most immersive and family-friendly free attractions in Switzerland.
6. Maison Cailler, Broc – A Chocolate Journey Like No Other
Included with Swiss Travel Pass
Switzerland and chocolate are inseparable — and nowhere is this more deliciously demonstrated than at Maison Cailler in Broc, in the heart of the Fribourg countryside. Cailler is one of the oldest chocolate brands in the world, and its factory museum offers one of the most popular (and tasty) Swiss Travel Pass free experiences in the country.
The immersive guided tour takes visitors on a multisensory journey through the history of chocolate, from its ancient origins with the Mayas and Aztecs to its arrival in Europe and the birth of Swiss chocolate craftsmanship. The highlight? The grand finale tasting room, where you can sample as much Cailler chocolate as you like. Paired with a visit to the nearby medieval town of Gruyères, this makes for an unforgettable Swiss day pass itinerary.

7. Abbey Library of Saint Gallen – A UNESCO World Heritage Treasure
Included with Swiss Travel Pass
Considered one of the oldest and most beautiful libraries in the world, the Abbey Library of Saint Gallen (Stiftsbibliothek St. Gallen) is a UNESCO World Heritage Site and an absolute marvel of Baroque architecture and intellectual heritage. Founded in the 8th century, the library holds over 170,000 volumes, including some of the most precious medieval manuscripts in existence.
The ornate reading room — with its intricate woodwork, gilded ceilings, and the warm scent of centuries-old books — is one of the most awe-inspiring spaces in Switzerland. Visitors are given felt overshoes to protect the historic parquet floors, adding a charming ritual to the experience. This is a must-see for culture and history lovers travelling with the Swiss Travel Pass.

8. Matterhorn Museum, Zermatt – The Story Behind the World's Most Famous Mountain
Included with Swiss Travel Pass
The Matterhorn is arguably the most recognisable mountain on earth — and the Matterhorn Museum (Zermatlantis) in the car-free village of Zermatt tells its extraordinary story in remarkable depth. The underground museum is built around the authentic remains of a 19th-century Alpine village, creating a visually striking setting for exhibitions on mountaineering history, the first ascent of the Matterhorn in 1865, and the culture and traditions of the Zermatt valley.
Artefacts from the fatal first ascent — including the frayed rope that broke and cost four climbers their lives — are displayed with great care and context. It's a moving and fascinating museum that adds enormous depth to any visit to the Zermatt area. Easily reached by train (the Glacier Express passes through), it's a highlight of any Swiss Travel Pass itinerary through the Alps.

9. Château de Gruyères – A Fairytale Castle in the Fribourg Countryside
Included with Swiss Travel Pass
Perched on a hill above the medieval village of Gruyères — famous worldwide for its cheese — the Château de Gruyères is one of Switzerland's most beautifully preserved medieval castles. Dating from the 13th century and home to the counts of Gruyères for nearly 300 years, the castle offers sweeping views of the surrounding countryside and a rich journey through medieval life, Renaissance furnishings, and Swiss history.
The castle also houses a remarkable permanent exhibition of works by Swiss artist H.R. Giger, the Oscar-winning creator of the 'Alien' creature design — a fascinatingly unexpected addition to this fairy-tale setting. Combined with a visit to Maison Cailler just down the road, Gruyères makes for one of the most rewarding and picturesque free day trips in Switzerland with the Swiss Travel Pass or Swiss day pass.

10. International Museum of the Reformation, Geneva – Where History Changed the World
Included with Swiss Travel Pass
Geneva was one of the most important epicentres of the Protestant Reformation in the 16th century, and the International Museum of the Reformation brings this pivotal chapter of world history to life in vivid detail. Located in a historic mansion in the heart of Geneva's old town, just steps from St. Peter's Cathedral where reformer John Calvin preached for over 20 years, the museum is a rich and scholarly exploration of how the Reformation reshaped religion, politics, science, and culture across Europe and the world.
Its collections include rare books, manuscripts, portraits, and artefacts from the 16th century, all presented in beautifully designed, accessible exhibitions.

How to Make the Most of Your Swiss Travel Pass
The Swiss Travel Pass grants free entry to over 500 museums and attractions across the country — but choosing the right ones for your itinerary makes all the difference. Here are a few practical tips:
Plan by region: Switzerland is compact but diverse. Group nearby attractions together — for example, the Musée Fort de Chillon and Chillon Castle (Vevey / Montreux area), Maison Cailler and Château de Gruyères (Fribourg countryside), or the Swiss National Museum and Abbey Library of Saint Gallen (German-speaking Switzerland).
Lean into the train network: The Swiss Travel Pass covers virtually all Swiss Federal Railways connections, making it easy to hop between cities and regions without any additional cost. Most attractions in this list are within a short walk of a train station.
Check seasonal openings: Some attractions, including Ballenberg, have limited winter hours. Always verify opening times on official websites before visiting.
Download the SBB app: The official Swiss Federal Railways app lets you plan journeys, manage your pass, and find nearby included museums in real time.
Why Start with the Musée Fort de Chillon?
Of all the Swiss Travel Pass free museums listed here, the Musée Fort de Chillon stands out as one of the most unique and least-known. Hidden beneath one of Switzerland's most photographed landmarks, it offers an underground adventure that most visitors to the region never discover. Combined with the adjacent Chillon Castle, it makes for an extraordinary half-day experience on the shores of Lake Geneva — two remarkable historic sites, both fully included with your Swiss Travel Pass, in one stunning lakeside location.
