6 of the Coolest Summer Destinations in Europe–Literally

The "Coolcation" is 2026's most relatable travel trend. After record-breaking temperatures across Southern Europe in 2024 and 2025, travellers are escaping the summer heat by looking north and upwards to the Alps. The European Travel Commission notes that "climate-driven destination shifts" are now a primary factor for 1 in 4 holidaymakers.

Active travellers looking for high altitude summer hiking and the best Alpine lakes for swimming will love the mountainous region, which offers a natural air-conditioning system. For every 1,000 metres you climb, the temperature drops by roughly 6.5°C. Here are some of the (literally) coolest destinations in Europe to consider for your 2026 summer travel plans.

1. Zermatt, Switzerland (1,608m)

Even in July, Zermatt feels like a fresh spring day. Because of its high altitude and the surrounding glaciers, it remains one of the few places in Europe where you can summer-ski on the Theodul Glacier. For a break from the slopes, you can descend 15 metres below the glacier’s surface into the Glacier Palace, a shimmering world of ice sculptures and centuries-old formations. Alternatively, take the Gornergrat Railway—Europe’s highest open-air cog railway—to witness the Riffelsee lake reflection, where the Matterhorn perfectly mirrors itself in the still, Alpine water.

2. Lake Oeschinen, Swizterland (1,578m)

This UNESCO World Heritage site is widely considered the most beautiful mountain lake in Switzerland. Fed by glacial brooks from the surrounding 3,000-metre peaks, the water temperature rarely exceeds 20°C. It’s a natural infinity pool that offers a literal "cool down" after a morning hike.

3. Obergurgl, Austria (1,930m)

As Austria’s highest parish, Obergurgl is famously known as the "Diamond of the Alps". At nearly 2,000 metres, the air is crisp and pure and the summer temperature is consistently 10-12°C lower than the sweltering valleys of Innsbruck or Vienna. You can dine at the Top Mountain Star, a futuristic glass-and-steel bar perched on a narrow ridge at 3,080m, offering a 360-degree view into Italy and Austria. History buffs will also love that this is where explorer Auguste Piccard made his emergency stratospheric balloon landing in 1931, an event that put this remote "glacier village" on the map and is celebrated in the local museum.

4. Val Thorens, France (2,300m)

As the highest resort in Europe, Val Thorens is the "Coolcation" capital. While the valleys below might be sweltering in a 38°C heatwave, this high-altitude playground stays pleasantly cool. It’s perfect for mountain biking and hiking without the risk of heat exhaustion. Thrill-seekers can zipline across the valley at speeds of up to 100km/h. For a more grounded but equally unique experience, there is also an authentic high-altitude farm where you can watch manual goat milking, explore a permaculture garden, and sample Belleville cheese matured right on-site.

5. Saas-Fee, Switzerland (1,800m)

Known as the "Glacier Village," Saas-Fee is surrounded by 13 four-thousand-metre peaks. The proximity to the ice keeps the valley floor temperate. It’s also car-free, meaning no tarmac-heated streets to deal with. Beyond the cool air, you can ride the Metro Alpin, the world’s highest underground funicular, to a revolving restaurant at 3,500m for a panoramic view of the literal "roof of Europe." For a touch of whimsy, the village is also famous for its tame mountain marmots at Spielboden, who are remarkably friendly and will often eat carrots right from your hand.

6. Cortina d’Ampezzo, Italy (1,224m)

While the rest of Italy bakes, the "Queen of the Dolomites" offers a refined, cool retreat. The world saw its snowy charms during the 2026 Winter Olympics, but not everyone knows its beauty in the summer. Explore the Lagazuoi Open-Air Museum, where you can hike through a fascinating network of restored WWI tunnels and trenches carved directly into the rock face, providing a cool, subterranean adventure that blends dramatic history with some of the most spectacular panoramas in the Italian Alps. The evening "Enrosadira" (where the peaks turn pink at sunset) is best enjoyed with a light jacket—a luxury that Rome or Florence simply can't offer in August.
