A two-hour drive southeast of Munich, and resting at the foot of Zugspitze mountain, the wonderfully clear Eibsee practically begs you to dive into its cool depths. Luckily, you can do exactly that – preferably in summer, when the water hits a welcoming peak of 20 degrees Celsius – after taking the seven kilometre hiking loop around the lake’s edge and working up a sweat.

Storybook villages reflected in glassy emerald water and a treasure trove of nearby cultural and historic sites define romantic Lake Orta in northern Italy’s mountainous region of Piedmont, just over an hour’s drive from Milan. History buffs will be lured to the island of San Giulio and its crowning Benedictine abbey, which lies at the heart of the lake, but lingering at Orta’s edges reaps rewards, too – the region’s many trails can be tackled by foot, bike, horse or even paraglider, depending on your appetite for adventure.

If you thought Greece was all about the sea and its islands, you might want to think again. Lake Vouliagmeni ("Sunken Lake") is a small, brackish water body fed by underground currents that seep in through Mount Hymettus. Half an hour south of Athens and fringed by dramatic rocky outcrops and caves, it’s a blissful spot for an afternoon dip.

George Clooney’s favourite European getaway needs little introduction but Lake Como – a 40-minute train ride from Milan – is more than just a celebrity-spotting haven. Gilded by Renaissance architecture and ringed by the Bergamo Alps, Italy’s third-largest lake is spectacular at almost every turn, especially when viewed from the balcony of Passalacqua, the latest offering from Como hotel royalty, where hand-blown Murano chandeliers and a swimming terrace lets you gaze into the Italian icon’s azure depths from unparalleled luxury. 

Fed by mountain springs, surrounded by mediaeval towns and watched over by 13th-century Château de Menthon-Saint-Bernard, Lake Annecy paints quite the enchanting picture. Dotted with pleasure boats in the summer, its light-dappled water – just under two hours’ drive from Lyon – beckons holidaymakers from all over Europe. With accommodation options ranging from camping to quaint bed and breakfasts and boutique hotels – the colourful Splendid Hotel Lac d’Annecy is footsteps from the water – staying for longer than an afternoon is an appealing proposition.

Two hours by car from Zurich and at an elevation of over 1500 metres, Oeschinen Lake in the Bernese Oberland has an alpine setting so spectacular it’s hard to beat. Although the area’s snow-dusted peaks and glacial brooks provide plenty to gaze at, there’s more on offer than sightseeing: there’s a ‘mountain coaster’ that shoots anyone over the age of three down the slopes in a self-controlled toboggan as well as rentable rowboats on offer. If you're determined to swim, it'll be a refreshing dip indeed – water temps here, even in summer, typically don't exceed 20C.

Located at the foot of the Lenangsbreen glacier on the Lyngen peninsula in the country’s far north, Blåisvatnet (the Blue Lake) and the intense colour that inspired its moniker more than earns its name (its vivid hue comes from the silt particles melting off the Lenangsbreen glacier, making the water a cold plunge-like option to say the least). Hiking trails that skirt the lake range from easy to difficult but no matter your choice of route, you’ll need appropriate footwear – hiking boots are mandatory. 

About an hour by car from both the Slovenian and Italian borders, Lake Weissensee in the Austrian state of Carinthia sits in the Gailtal Alps about 900 metres above sea level. The stunning waters are clean enough to drink, though you’ll likely have more fun swimming and sailing in them, activities that locals often partake in during the summer months when water temps can reach around 25C. It’s also a veritable playground in winter, with ice skating and alpine skiing particularly popular when the temperature drops.

Straddling the mountainous border between Macedonia and Albania, UNESCO-listed Lake Ohrid is a turquoise wonder, with water so transparent boats look as though they’re floating in mid-air. Ohrid’s old town, complete with Samuel’s Fortress and the ancient monastery of Saint Naum (both of which date back to at least the 900s), makes a visit to this natural and cultural marvel an essential addition to your Balkans itinerary.

Known as the ‘Hungarian Sea’, Lake Balaton is the largest freshwater lake in Central Europe and, for a landlocked country, it makes for one incredible swimming spot (expect temperatures of around 25C in summer). Glass-clear water fringed with sandy beaches, sprawling vineyards and rolling hills make Belaton – just an hour-and-a-half from Budapest by car – a worthy stop on your European road trip.

Lighthouses, farmland, stretches of talc-white sandy beaches… Lake Vättern is a strong contender for prettiest Swedish lake, in a hotly contested field. After a three-and-a-half hour car journey from Stockholm, stretch your legs on a stroll along splendid Motala Harbor before taking a dip in the water’s chilly depths (even in the peak of Swedish summer, its temperature rarely rises above 18 degrees celsius).

Italy’s Lake District, about an hour by car from Verona, isn’t exactly a secret. If you visit in autumn, it certainly feels like one, however. Not only can you enjoy the beauty of Italy’s largest lake and its surrounding historic villages without the crowds, the region will also likely be dressed in ruby and amber hues: nearby Parco Giardino Sigurtà, a few kilometres from the lake’s southern tip, is home to over 500 Japanese maples that erupt in fiery reds come fall.

Millions of visitors flock to this glacier-formed lake in Germany’s Black Forest each year, a scenic hour-and-a-half hour drive from Basel, in Switzerland’s north.  Despite Titisee’s popularity, finding tranquillity here isn’t difficult – the surrounding woodlands are mostly flat and ideal for an easy stroll, while hireable small boats allow visitors the chance to drift on its gently ebbing surface.

A maze of channels and inlets boasting thousands of islands, Saimaa is Finland’s biggest lake, spanning over 4,000 kilometres and fringed by countless towns and cities. Base yourself in Savonlinna, home to the majestic Olavinlinna Castle and just over three-and-a-half hours’ drive northeast of Helsinki, to soak up the fascinating history of the region, which stretches back to the late 15th century.

The crescent-shaped Lake Geneva stretches across a portion of the French-Swiss border, forming one of Western Europe’s biggest bodies of water. Here, it’s a choose-your-own-adventure of waterfront fun, but the best way to take in its beauty is via a boat cruise from the Swiss town of Lausanne – an hour south-west by car from Bern – to the island-castle of Château de Chillon, which takes in views of Lavaux vineyards and is just under two hours long.

Even symbolist painter Gustav Klimt couldn’t resist the charms of Austria’s glittering Attersee, less than an hour from Salzburg – the lake inspired several of his most famous landscape paintings. Attersee is particularly tempting in summer, when average water temperatures hover around the mid 20 degrees Celsius range. But no matter the time of year you visit, its perpetually pretty backdrop almost outshines scenes from The Sound Of Music.

Quaint rowboats dotting the shoreline and a purpose-built sauna house metres from the water make a trip to Lake Tõhela in Western Estonia, two hours by car from Tallinn, an authentic Balkan experience. Fishing, swimming and hiking are all on the agenda here but for a change of scenery, Tõhela’s tiny 16th-century village, which has a population of just 51, is also well worth popping into for a coffee pick-me-up.
