While sunshine is - arguably - crucial for a successful summer holiday, its intensity is now reaching critical limits.
Over recent years, temperatures have steadily climbed to unbearable levels, rendering many traditional beach destinations 'no-go zones' throughout July and August.
Summer 2024 was Europe's hottest on record, with land temperatures a stark 1.54°C above the 1991-2020 average.
Already this year, Spain and Portugal have registered unprecedented highs of 46°C for June.
For those who’d prefer not to burn like a sausage on a grill, finding an alternative holiday option is a priority. According to a recent report from the European Travel Commission, holidaymakers are now seeking milder destinations.
Europe’s mountains are an obvious choice.
Heidi is one of several ski companies now offering summer breaks at higher altitudes at 20 resorts across Austria, Slovenia, Poland, Italy and France.
“We genuinely believe people are happier and healthier from spending time in the mountains, come winter or summer. While mountain resorts have cooler temperatures than the most popular hot spots in the Med, they still offer plenty of summer sunshine and swimming opportunities,” says the company’s co-founder, Marcus Blunt.
Here are a few of the refreshing above-sea-level breaks where it’s possible to soak up sunshine and swim in freshwater lakes.
Lake Bohinj, Slovenia
Average summer temperature: 25°C
Celebrated by Lonely Planet as one of the best wild swimming spots in Europe, Lake Bohinj promises refreshingly clear waters and mighty mountain views of the Julian Alps. Located in a glacial valley 500metres above sea level in the Triglav National Park, it’s a relaxing base for hikes reached by a cable car. Explore the rapids, waterfalls and imagination-bending rock formations of the Mostnica Canyon and look out for signs of lynx, bears and wolves. Wind down at Hotel Bohinj, close to the lake, where a wellness centre features a Finnish and Turkish sauna.

A private beach gives access to the lake and motorboat rides depart from the hotel’s own marina. From the lake’s midpoint, it’s possible to see the mountain borders with Italy to the west and Slovenia to the south. Find even more respite from the heat with a visit to Kranzelbinder gem store and fossil museum in nearby Portschach, which has an underground sensory crystal room.
