20 Things To Do With Kids Around Lake Geneva When It's Hot
⛰️ Head for the Hills — Cool Down with Altitude
1. Rochers de Naye — Montreux, Switzerland
Sitting at over 2,000 metres above Montreux, Rochers de Naye is one of the most rewarding half-day trips in the region. A vintage rack-and-pinion train climbs from Montreux station through vineyards and forests before emerging into an alpine world where temperatures are reliably 10–15°C cooler than the lakeside. Alpine gardens, marmots and jaw-dropping views over Lake Geneva make this a hit with children of all ages.
2. Peak Walk at Les Diablerets — Swiss Alps
At nearly 3,000 metres on the Glacier 3000 above Les Diablerets, the Peak Walk by Tissot is the world’s first suspension bridge connecting two mountain peaks. Even in the height of summer, temperatures up here hover around 10°C — pack a light jacket. Accessible by cable car from Reusch, this is a genuinely unforgettable experience for families looking for a dramatic dose of altitude and cool air.
3. Moléson — Gruyères Region, Switzerland
Rising to 1,972 metres above the Gruyères countryside, Moléson is reached by cable car and chairlift from the village below. The summit offers sweeping views across the Alps and pre-Alps, and the cooler mountain air is a welcome relief from the summer heat. Kids love the summer toboggan run on the way down — a rail luge that adds an extra dose of excitement to the descent.
4. Fantasticable — Châtel, Haute-Savoie, France
For thrill-seeking families, Le Fantasticable in Châtel is one of Europe’s longest zip lines, launching riders from the mountain summit on a high-speed flight above the alpine meadows. The altitude keeps things fresh and the adrenaline keeps things exciting. Age and weight restrictions apply — check directly with the site before booking.
🌊 Water, Waves & Swimming
5. Aquaparc — Le Bouveret, Switzerland
The largest water park in French-speaking Switzerland, Aquaparc sits right on the eastern shore of Lake Geneva at Le Bouveret. Giant slides, wave pools, children’s splash zones and outdoor sunbathing areas make this a full-day family destination. Online booking is strongly recommended during peak summer weeks.
6. Swimming at Divonne-les-Bains — Ain, France
Just a short drive from Geneva, the spa town of Divonne-les-Bains offers a large, well-equipped leisure lake with a supervised sandy beach, water sports and picnic areas. An accessible, affordable and genuinely pleasant option for families looking to cool off on the French side of the border.
7. Swiss Vapeur Parc — Le Bouveret, Switzerland
Best known for its miniature steam trains, Swiss Vapeur Parc has recently added a brand-new cool water zone designed specifically for hot summer days. Young children adore the water play structures and the miniature railway rides. A charming, relaxed park that pairs perfectly with a visit to nearby Aquaparc.
🏛️ Museums & Cultural Sites — Air-Conditioned Bliss
8. Mines of Bex — Bex, Canton of Vaud, Switzerland
For a truly spectacular natural air-conditioning experience, nothing beats the Mines of Bex (Mines de Sel de Bex). These centuries-old salt mines maintain a constant temperature of around 14°C year-round — a refreshing shock after the summer heat outside. Guided underground tours wind through hand-carved galleries, salt lakes and dramatic light installations. One of the most genuinely unique family experiences in the entire Lake Geneva region.
9. Olympic Museum — Lausanne, Switzerland
Lausanne is the world capital of the Olympic movement, and the Olympic Museum is its crown jewel. Interactive, immersive and genuinely exciting for children, this state-of-the-art museum traces the history of the Olympic Games from Ancient Greece to the present day. It’s fully air-conditioned, with stunning views over Lake Geneva from its hilltop terrace. Perfect for sporty families with children aged 7 and up.
10. Fort de Chillon — Villeneuve Region, Switzerland
Most visitors know Chillon Castle — far fewer know about the Fort de Chillon, a military underground fortification carved directly into the rock face nearby. This hidden gem offers a fascinating insight into Swiss national defence history in a naturally cool, atmospheric underground setting. A brilliant off-the-beaten-track alternative for curious families.
11. Geneva’s Museums — Geneva, Switzerland
Geneva is a treasure trove of family-friendly museums, most of them air-conditioned and free or low-cost. The Natural History Museum, the Museum of the History of Science, the Patek Philippe Museum and the Art and History Museum are among the standout options. A rainy — or scorching — day in Geneva need never be wasted.
12. Gruyères Museums — Gruyères, Switzerland
The perfectly preserved medieval village of Gruyères is home to several extraordinary museums. The HR Giger Museum, dedicated to the Swiss artist who created the alien universe, is dark, surreal and endlessly fascinating for older children and teenagers. The Tibet Museum and the Gruyères Castle complete a cultural visit that can easily fill a full day. Combine with a taste of the region’s famous cream desserts.
13. Fondation Gianadda — Martigny, Switzerland
The Pierre Gianadda Foundation in Martigny is one of Switzerland’s most respected cultural institutions. Each summer it hosts internationally acclaimed temporary exhibitions in a beautifully designed museum space. The outdoor sculpture park and the Gallo-Roman archaeological museum add extra dimensions to a visit. A must for art-loving families.
14. Chaplin’s World — Corsier-sur-Vevey, Switzerland
Set in the hillside villa where Charlie Chaplin spent the last 25 years of his life, Chaplin’s World is one of the most charming and moving museums on the Swiss Riviera. Wax figures, immersive film sets, personal archives and beautifully kept gardens bring the life of the great comedian vividly to life. Genuinely enjoyable for both children and adults.
15. Musée de la Musique Mécanique & Alta Lumina — Les Gets, Haute-Savoie, France
The mountain resort of Les Gets offers a wonderful cultural double bill. The Museum of Mechanical Music houses a rare and enchanting collection of self-playing instruments from across the centuries. Alta Lumina is a magical illuminated night walk through the forest — a sensory, story-driven experience perfect for families on warm summer evenings when the daylight finally fades.
🏰 Heritage & History in the Shade
16. Château de Ripaille — Thonon-les-Bains, France
Tucked into the wooded shoreline of Lake Geneva at Thonon-les-Bains, the Château de Ripaille is a beautifully preserved medieval castle surrounded by ancient forests and vineyards. The shaded grounds, walking trails and guided château tours offer a peaceful, cool retreat from the summer heat on the French side of the lake.
17. Palais Lumière — Évian-les-Bains, France
The stately Palais Lumière in Évian-les-Bains is a magnificent Belle Époque former thermal spa building, now reinvented as a high-quality cultural and exhibition space. With its thick stone walls and elegant interiors, it stays naturally cool even on the hottest days. A refined cultural stop just steps from the lake on the French shore.
18. Fort des Rousses — Jura, France
About 90 minutes from Lake Geneva in the Jura mountains, the Fort des Rousses is a 19th-century military fortification that has been brilliantly repurposed as a Comté cheese ageing cellar. Underground tours combine military history with the extraordinary sight of thousands of Comté wheels maturing at a constant cool temperature. Unusual, educational and genuinely loved by children — especially the cheese tasting at the end.
🌿 Cool Nature Escapes
19. Gorges du Pont du Diable — Vallée d’Aulps, Haute-Savoie, France
Hidden in the Vallée d’Aulps above Thonon, the Gorges du Pont du Diable (Devil’s Bridge Gorges) are a spectacular natural canyon carved by a rushing mountain torrent. The sheer rock faces, turquoise pools and cascading waterfalls create a naturally cool microclimate that offers instant relief from the heat. A well-maintained family walking path runs along the gorge, making it accessible for children and pushchair users on the flatter sections.
🍽️ A Panoramic Pause
20. Kuklos Rotating Restaurant — Leysin, Switzerland
High above the Rhône Valley in the resort of Leysin, the Kuklos is a slowly revolving panoramic restaurant offering a full 360° sweep of the Alps and Lake Geneva.
