Rainy day activities in Switzerland: what to do when the weather turns

When the mountains disappear

You planned for sunshine. You arrived in Switzerland with a mental slideshow of alpine meadows, turquoise lakes, and Matterhorn silhouettes against a blue sky. And then the clouds rolled in, the rain started, and the visibility dropped to approximately one metre.

This happens. Switzerland is a mountainous country with unpredictable weather, and even in summer the mountains can vanish inside clouds for days at a time. The good news is that Switzerland is also a country with exceptional indoor culture — world-class museums, thermal baths, extraordinary trains that cut through the rain, cosy restaurants built for exactly this kind of weather, and a culture that treats staying inside with a hot drink as a perfectly dignified activity.

Here’s how to make a rainy Swiss day excellent rather than disappointing.

Museums worth the detour (and your time)

Switzerland punches far above its weight for museum culture. The country’s museums are exceptionally well-funded, well-curated, and genuinely engaging rather than dusty heritage warehouses.

In Zurich:

The Kunsthaus Zurich is one of Europe’s finest art museums, with a collection spanning from medieval altarpieces through Giacometti (a Swiss artist with an enormous presence here) to contemporary installation art. The new wing added in 2021 more than doubled the exhibition space. Allow at least half a day.

The Swiss National Museum (Landesmuseum Zurich) sits in a neo-Gothic castle next to the main station. It covers Swiss history and culture from prehistoric times to the present day, and the 2016 renovation dramatically modernised the visitor experience while preserving the character of the building. Admission is covered by the Swiss Travel Pass.

The Museum Rietberg specialises in non-European art and has one of the most beautiful settings in Zurich — a villa park in Rieterberg that’s pleasant even in light rain. The collection includes extraordinary works from Africa, Asia, the Americas, and Oceania.

In Lucerne:

The KKL (Culture and Congress Centre) Lucerne is an architectural masterpiece by Jean Nouvel, sitting on the lakefront. The Concert Hall inside hosts world-class classical performances — check the schedule and buy tickets if anything interesting is on during your visit.

The Rosengart Collection is a small, exquisite private museum in central Lucerne housing one of Europe’s finest collections of Picasso and Paul Klee works. It’s intimate in the best way — you can spend genuine time with individual pieces rather than filing past them in crowds.

In Basel:

Basel has a genuinely remarkable museum density. The Kunstmuseum Basel is one of the world’s oldest public art museums and holds an extraordinary collection including Holbein the Younger, Cézanne, and a superb Picasso room. The Beyeler Foundation in nearby Riehen is a private museum with a world-class modern and contemporary collection in a Renzo Piano building — easily one of the best museum experiences in Switzerland.

The Lindt Home of Chocolate (near Zurich):

The Lindt Home of Chocolate museum in Kilchberg is exactly what a rainy afternoon needs: an engaging, well-designed museum about the history and craft of Swiss chocolate, complete with the world’s largest chocolate fountain, generous tasting opportunities, and a shop where you can spend irresponsibly. It’s educational, genuinely fun, and you leave happier than you arrived. Book in advance during summer.

For chocolate tours and chocolate-focused experiences more broadly, rainy days are honestly the ideal time — no competing desire to be outside.

Trains: scenic even in the rain

Swiss trains cut through the weather. While mountain cable cars close in heavy rain and fog, intercity trains continue running with Swiss regularity, and the views through train windows in moody weather can be spectacular in their own right — misty lake shores, green valleys with fog sitting in the trees, Rhine gorge scenery emerging from cloud.

The Glacier Express from Zermatt to St. Moritz runs regardless of weather and the panoramic carriages still deliver extraordinary scenery even when the high peaks are hidden. The low and mid-altitude valley sections — the Rhine gorge between Chur and Disentis, the Goms valley in the Valais — are particularly dramatic in overcast conditions.

The Bernina Express between Chur and Tirano (Italy) crosses the Bernina Pass at 2,253 metres. In rain, the waterfalls running off the surrounding slopes are dramatically increased, and the Morteratsch Glacier area has its own haunting quality in cloud.

Closer to cities, the GoldenPass Panoramic between Montreux and Zweisimmen rolls through the wine terraces of Lavaux (UNESCO listed) and into the Pays-d’Enhaut alpine landscape. Even in mist, the terraced vineyards above the lake have a moody beauty.

You can book the Glacier Express from Zermatt to St. Moritz in advance. If you’re travelling on the Swiss Travel Pass, the pass covers the journey cost and you just need the seat reservation (CHF 39-49).

Thermal baths and wellness

Switzerland has a strong thermal bath culture, and rainy days are arguably the best time to experience it — you’re already wet, you may as well be comfortably warm and wet.

Therme Vals in the remote village of Vals (Graubünden) is one of the most architecturally celebrated buildings in Switzerland — Peter Zumthor’s 1996 thermal bath building is widely considered a masterpiece of contemporary architecture. The experience matches the building: dim light through quartzite stone, steaming thermal water, silence, and a remarkable meditative atmosphere. Book well in advance; visits are timed to manage numbers.

Bad Ragaz near Chur in eastern Switzerland uses thermal spring water from the Tamina Gorge that has been channelled here since the 14th century. The Grand Resort Bad Ragaz includes extensive thermal facilities accessible to day visitors, and the Tamina Therme is a modern wellness complex using the same historic spring.

Lavey-les-Bains in Valais is Switzerland’s hottest natural thermal spring, with water emerging at 65°C and cooled to bathing temperature. The modern spa complex is relaxed and excellent value compared to the famous-name alternatives.

In Zurich, the Thermalbad und Spa Zurich occupies a remarkable converted 1880s waterworks building in the city centre. The industrial architecture is extraordinary and the rooftop outdoor thermal pool offers improbable city views regardless of weather.

Food: rainy days are made for Swiss cuisine

Switzerland’s cold-weather food culture — fondue, raclette, rösti, hearty soups, rich broths — was designed for exactly this kind of day. A rainy afternoon in Switzerland is arguably the best possible time to sit in a restaurant and eat properly.

Fondue requires booking at the good spots, particularly in tourist towns. Don’t wander in and expect to sit immediately on a rainy afternoon in Grindelwald or Lucerne. Book ahead by a day where possible.

Raclette — the half-wheel of cheese melted under a grill and scraped onto potatoes with cornichons and pickled onions — is available at most traditional Swiss restaurants. It’s even more intensely comforting than fondue on a cold, wet day.

Rösti (the Swiss potato cake, done well) is deceptively difficult to get right and genuinely excellent when it is. Topped with fried egg and bacon (Rösti Bernoise), or as a side to a mountain-style platter, it’s one of Switzerland’s most honest comfort foods.

The Coop and Migros supermarkets are also worth noting for rainy days — picking up good bread, local cheese, and wine from a Coop Supermarché or City Coop and having an impromptu indoor picnic in your accommodation is entirely reasonable and often excellent.

Indoor markets and covered shopping

Many Swiss cities have covered market halls or arcades that are perfectly suited to rainy-day exploration.

In Bern, the famous Arcades (Lauben) — the covered colonnade walkways running through the old town — mean you can walk for kilometres through the city centre without getting wet. Bern is arguably the most rain-friendly city in Switzerland precisely because of this infrastructure.

In Basel, the indoor Markthalle food hall near the train station is a good stop for lunch or coffee, with a range of food stalls and a pleasant atmosphere.

In Lucerne, the covered walking area around the old town and along the riverfront means you can cover most of the highlights without excessive exposure to rain, though the Chapel Bridge itself is obviously open to the sky.

Practical rainy day planning tips

Check the forecast by valley, not just by city. Swiss weather is highly localised. Rain in Interlaken doesn’t necessarily mean rain in the Rhône Valley or Ticino. Checking the MeteoSwiss app (Switzerland’s national weather service, available in English) by specific location gives much better information than generic Switzerland forecasts.

Ticino is often sunnier. When the rest of Switzerland is under cloud, Ticino (the Italian-speaking canton south of the Alps) often sits in Mediterranean sunshine. If you have flexibility, a bad-weather day is a good day to head south on the Gotthard tunnel train.

Mountain cable cars vs mountain trains. Heavy rain and strong winds close cable cars but usually not cogwheel trains. The cogwheel railway to Jungfraujoch, the Rigi Bahn, and the Pilatus Bahn (in appropriate weather) all operate in conditions that would ground cable car services.

Bring layers and waterproofs regardless. Even summer days in Switzerland can turn quickly at altitude. A lightweight waterproof jacket takes up minimal space and changes the quality of a rainy day from miserable to merely damp.

For broader trip planning ideas whatever the weather, the 7-day itinerary has a full framework that can be adjusted based on conditions. And if the rainy day catches you in Interlaken, the range of indoor activities there is better than its outdoor adventure reputation might suggest.

Rain in Switzerland is not a disaster. It’s an opportunity to eat better, visit museums properly, and experience a country that knows how to make indoor time comfortable. The mountains will still be there when the clouds lift — probably looking even better for the contrast.
