Majestic mountains, gleaming glaciers, charming rural sights – the natural beauty of Europe’s many national parks is nothing if not diverse. From humbling Scottish Highland vistas to otherworldly Icelandic ice caves, feast your eyes upon 15 of the most beautiful parks on the continent.

The Brecon Beacons is just a 90-minute car journey away from the Welsh capital of Cardiff. This rugged, mesmerising mountain range covers 520 square miles (1,347sq km), and is home to a rich array of wildlife, including otters, badgers and Welsh Mountain Ponies. Established in 1957, it’s one of three national parks in Wales, along with the Pembrokeshire Coast and Snowdonia. 

The National Showcaves Centre for Wales has immense caves and Llangorse Lake is popular with windsurfers. The park is a well-regarded stargazing destination since becoming the first International Dark Sky reserve in Wales in 2012, so camping is also a hit here. A hike up to see the waterfalls of the Four Falls Trail, or to southern Britain’s highest point, the 2,907-foot (886m) peak of Pen y Fan, is often on visitors' agendas.

Home to giant, sweeping valleys and wild, open moorlands, the Cairngorms is accessible in 45 minutes by car from Inverness. The park covers a staggering 1,748 square miles (4,527sq km), making it the largest national park in the UK, followed by the Lake District National Park. Wildlife lovers, take note: it’s home to 25% of the UK’s rare and endangered species.

Keen climbers head here to scale some of the UK’s highest mountains including Ben Macdui, Braeriach and Cairn Toul. Even its smaller mountains – like the 3,294-foot (1,004m) Devil's Point, pictured – brood with character. As well as hiking and biking, snow bunnies will love Glenshee Ski Centre and history lovers the wonderful 17th-century Braemar Castle.

In southeast Germany, the sprawling, unspoiled Bavarian Forest National Park extends almost 94 square miles (243sq km). The country’s first national park, founded in 1970, can be reached in just over two hours from Munich. It straddles Germany’s border with the Czech Republic, and with Bohemian Forest in the next-door country, is the largest protected woodland in Central Europe. Familiar sights include wildcats like the native lynx (pictured), wolves, boars and brown bears.

Things to see and do include motorbiking on Grosser Arber mountain, wildlife watching at the Tierfreigelande open air habitat plus tobogganing and snowshoeing. The forest offers over 300 miles (483km) of marked trails, but the best might be the wooden tree top boardwalk Baumwipfelpfad Bavarian Forest, complete with a 144-foot (44m) observation tower.

Next, a beautiful swathe of northern England stretching 555 square miles (1,437sq km), spanning Derbyshire, Cheshire, Greater Manchester, Staffordshire, West Yorkshire and South Yorkshire – the picturesque Peak District. It’s the UK’s first National Park, established in 1951. Accessible in just over an hour by car from Manchester, it’s home to an array of charming sights, from the Victorian Midland Railway Headstone Viaduct, (pictured) dating back to 1863, to Peveril Castle, dating from 1080.

Top sights such as the Salt Cellar rock formation, or the 1,696-foot high (517m) Mam Tor, can be accessed on foot. Elsewhere, activities include a wander around the splendid gardens of Elvaston Castle Country Park, treetop rope courses at Go Ape and, for a boat trip with a difference, the flooded 18th-century lead mine Speedwell Cavern. See more of the world's most amazing caves.

Distinguished by jagged mountains, steep slopes, giant plateaus and green-blue water, you’ll find the 444-square-mile (1,150sq km) Jotunheimen National Park in the heart of Norway. The capital, Oslo, is four hours south by car. It’s home to 29 of Norway’s highest mountains, including the tallest, Galdhøpiggen, at 8,100 feet (2,469m), and the strikingly cone-shaped Kyrkja, pictured here.

Visitors love to soak up undisturbed valleys on horseback and hike the 186 miles (299km) of marked trails, including the stunning Besseggen ridge, usually walked by over 60,000 people a year. Along its 3,608-foot (1,100m) rise, there are views of the crystal-clear waters of both Gjende and Bessvatnet lakes, plus elegant animals like reindeer and elk.

Vibrant valleys, mystical lakes and densely-forested mountains define Ireland’s Killarney National Park, established 1832. It’s found in the southwest of the county, 90 minutes from Cork, and covers 40 square miles (104sq km). People usually head here to conquer Ireland’s tallest mountain range, the MacGillycuddy's Reeks. Elsewhere, the serenity of Upper, Muckross and Lough Leane lakes can be enjoyed, along with the magic of the 66-foot (20m) high Torc Waterfall.

The 15th-century Ross Castle, a commanding presence on the shores of Leane, the largest of the lakes, is one of Killarney’s most iconic sights. A more modern attraction is the 19th century lakeside Muckross House, with its handsome exterior and manicured gardens. Popular outdoor pursuits revolve around the lakes, from kayaking and boat touring to cycling loops.

Covering almost 115 square miles (298sq km), Plitvice Lakes National Park is found near the Bosnia and Herzegovina border, two hours south by car from Zagreb. The park, founded in 1949, is famous for its collection of 16 crystal clear, colour-changing lakes – they morph between shades of green and blue due to their high mineral content – plus over 90 waterfalls. See more of the world's most beautiful waterfalls here.

The lake formations call for slow, meditative walking, via easy trails and pleasant, water-crossing boardwalks. People admire cascading waters – including the 229-foot (70m) Veliki Slap, shimmering with mist – at their leisure. But beware: swimming is prohibited in the park.

Despite its name, Bohemian Switzerland National Park is not in Switzerland, but the north of the Czech Republic, just over two hours from Prague. (It’s connected to Saxon Switzerland National Park, across the border in Germany.) Featuring dramatic rock formations, alluring pine forests and relaxing streams, 18th-century Swiss artists Adrian Zingg and Anton Graff inspired the name, when they noted that elements of its 30.5 square miles (79sq km) reminded them of home.

One iconic sight is the Pravčická Archway: spanning 85 feet (26.5m), it's the largest natural sandstone arch in Europe. It's easily reached via walkways and steps, and there’s a pretty chateau next door called the Falcon’s Nest, dating from 1881. A boat ride up the craggy, charismatic Kamnitz or Kamenice gorges is a bit more relaxing though.

In northeast Spain bordering France, Ordesa y Monte Perdido National Park spans over 60 square miles (155sq km) and since 1997 it's been a UNESCO World Heritage Site. It includes part of the Pyrenees mountain range, a natural border between the two countries. It’s three and a half hours by car from Barcelona and under two and a half hours from Zaragoza. Founded in 1918, Spain's oldest park is characterised by dramatic drops and the limestone valleys of Ordesa (pictured), Pineta, Anisclo and Escuain. 

Popular outdoor activities include paragliding and mountain biking, on which there are scenic waterfalls, lofty peaks – the highest, Monte Perdido, is 11,000 feet (3,355m) and a serious climb – plus storybook beech and oak forests.

Established 1973, Vikos National Park is flecked with deciduous and coniferous forests, and covers 49 square miles (127sq km) of northeast Greece, near the Albanian border. It's remote, with Thessaloniki reachable in three hours. However, it's worth the trip with Vikos celebrated for its breathtaking Vikos Gorge, plus interesting rock formations like the Stone Forest.

The park's traditional stone bridges cross one of Europe’s cleanest rivers, the Voidomatis, while a cobblestone path leads to the Monastery of Saint Paraskevi, which dates from the 15th century. There are viewpoints for those on foot aplenty, but another great way to see the gorge is by car, on winding mountain roads such as these. See more of the world's amazing roads here.

In remote northeastern Finland, you'll find the 104-square-mile (269sq km) Oulanka National Park. Established in 1956, it’s a day's drive from the capital, Helsinki, although there’s an airport in the tiny town of Kuusamo, only 50 minutes away. It’s twice been expanded (in 1982 and 1989); there are evergreen forests, turbulent rapids and Siberian-esque natural beauty, as the park shares a border with Russia.

Beautiful year-round, this park attracts many adventurous travellers during winter when activities include riverside snowshoeing and cross-country skiing, with accommodation in traditional wooden cabins. Wildlife lovers should keep their eyes peeled, as there are around 400 protected species of animals and plants in the region, with the chance to see everything from woodpeckers in late winter to calypso orchids at the start of spring. 

One of 20 national parks in the Netherlands, Hoge Veluwe is one of the oldest, having been established in 1935. Measuring 21 square miles (54sq km), it has some of the most diverse landscapes of any park on this list. Think heather-strewn heathland, dense forests, peat bogs and gentle rolling sand dunes. It’s found in the centre of the country, an hour’s drive from Amsterdam. Meanwhile, Apeldoorn is just 19 minutes by car. 

There's an abundance of wildlife to see such as foxes, Corsican sheep, wild boar and red deer. As well as bird-watching and biking, a major draw is the on-site Kröller-Müller Museum, home to the world's second-largest Van Gogh collection.

To the Land of Fire and Ice: Iceland. There you'll find the 5,460-square-mile (14,141sq km) Vatnajökull National Park, the largest in Europe. A UNESCO World Heritage Site that can be reached in around four hours from the capital city, Reykjavik, this chilly playground is found in south Iceland around the Vatnajökull glacier, which itself covers 8% of Iceland’s land mass.

Created in 2008 after the merging of Jökulsárgljúfur and Skaftafell parks, Vatnajökull is known for grand, snowy mountains, powerful waterfalls, glacial lagoons and sparkling ice caves. Glacier hiking, ice climbing, snowmobiling and jeep tours are all popular here.
