3 Days: Geneva, the Alps and Lake

Three days is exactly enough time to stop treating Geneva as a standalone city and start using it the way locals do: as a launchpad onto the Swiss rail network. You get two full days in Geneva itself (our Geneva travel guide covers those two days in full depth), then on day three you get on a train and go see something entirely different, all without checking out of your hotel. That’s the move. Shorter on time, drop to the 2-day version ; got a fourth day, the 4-day plan adds Montreux.

Day Focus Distance/time from Geneva
1 Lake, Old Town, the essentials In town
2 CERN, Reformation Wall, a proper swim In town
3 Day trip to Lausanne 35-45 min train

Book these before you go:

Day 1: The lake, the Old Town, the essentials

Get from GVA to Cornavin by train (6-7 minutes, about CHF 3), then walk down to the water. The Jet d’Eau throws lake water 140 meters into the air and it’s worth seeing from close range on the Eaux-Vives side, not just from a distance. Climb into the Old Town after: St Pierre Cathedral is free, and the narrow tower stairs cost around CHF 5 for a rooftop view over the lake that photographs never quite capture. Sit for a coffee at Place du Bourg-de-Four, then walk south across the Arve into Carouge for dinner. It’s an old Sardinian-built quarter with Italianate courtyards and it’s a more rewarding wander in my opinion than the more famous Old Town streets you just came from, and dinner there costs noticeably less than the lakefront terraces.

Day 2: CERN, the Reformation Wall, a proper swim

Book CERN online before you arrive, ideally weeks ahead; individual entry to the Science Gateway is free, though the guided tours into the underground experiments only open two hours before departure, from 8:30am, so treat that part as a same-day gamble rather than a plan. Spend your morning there regardless. It’s the best free thing in the city.

In the afternoon, walk through Parc des Bastions to the Reformation Wall, then head to Bains des Paquis for a swim and the fondue, about CHF 27 a person and better value than almost anything on the postcard side of the lake. If your travel dates line up with an advance UN booking (passport required, checked at the gate, no exceptions), the Palais des Nations tour is worth an afternoon too, though I’d still put CERN first if you’re choosing.

Day 3: Day trip to Lausanne

This is where the three-day version earns its keep. Trains from Cornavin to Lausanne run every 15-20 minutes and take 35-45 minutes, no reservation needed, so there’s no reason to sleep anywhere but Geneva even with a full day trip planned.

Lausanne is built on a hillside above its own stretch of the lake and it has a different energy than Geneva, younger, steeper, more student-driven. Head straight for the Olympic Museum on the lakefront: full adult admission runs about CHF 20, reduced CHF 14, and it’s genuinely well done, not a corporate vanity project, tracing the Games from Athens 1896 through to the present with enough interactive stuff to keep you there two hours easily. Walk the Olympic Park gardens outside afterward, right on the water, for free.

Grab lunch in the old town up the hill around Place de la Palud before catching an afternoon train back. You’ll be at dinner in Geneva by evening, which is the whole point of doing it this way instead of packing and moving hotels for one museum.

Logistics that make this work

Any registered Geneva hotel or hostel issues the free Transport Card automatically, covering TPG transit, Leman Express trains (which is what actually gets you toward Lausanne), and the Mouettes boats, for your entire stay including the day trip. Don’t rent a car anywhere in this itinerary; between the card and Swiss rail punctuality, it’s dead weight.

Remember Geneva is French-speaking, one of Europe’s priciest cities, and runs on strict lunch and dinner windows with kitchens closed in between, so plan your meals around noon to 2pm and 7 to 9:30pm rather than assuming all-day dining. Book both CERN and the Lausanne train timing before anything else, since everything on day 3 depends on catching a specific departure.
