The most beautiful castles in Europe

Pena National Palace (Sintra, Portugal)

As its name suggests, Pena National Palace is technically more a palace than a castle. But thanks to architect Baron Wilhelm Ludwig von Eschwege’s interest in castles along the Rhine, Pena’s design and construction are reminiscent of many castles in Europe.

This brightly colored palace sits high in the Sintra Mountains and is as impressive inside as it is out. The 360-degree views across the valley, towards the Atlantic Ocean and down over the town of Sintra give this unique corner of Portugal a distinct fairytale feel.

Insider tip: Sintra is packed full of fascinating castles and attractions. Don’t try to visit them all; don’t be tempted to walk between them. Pick one or two that interest you, and purchase a round-trip bus ticket on arrival to save time and money.

How to get there: There are regular trains to Sintra from Lisbon, and the journey takes approximately 45 minutes. Once in the town of Sintra, buy a bus ticket to get you to the Pena National Palace and other attractions.

Mont Saint-Michel (Normandy, France)

Mont Saint-Michel attracts more than 3 million visitors to its gates each year, which makes it one of the most popular castles in Europe. Unlike many other French castles, Mont Saint-Michel started out as a monastery rather than a strategic building or defensive structure. Its unique location – some 650 yards from land – also adds to its mystery and allure.

At low tide it may seem as if you can take a comfortable walk along the sandy bay to reach Mont Saint-Michel. But it’s not unheard of for visitors to fall victim to the deep mud and dramatic tide that whips in around it, turning the seemingly accessible estate into an eerily isolated, albeit somewhat palatial, island with just a single entrance road.

Insider tip: Pack a good pair of walking shoes and plenty of water. The only way to get around the castle is on foot; you can expect some stairs along the way.

How to get there: If coming from Paris, take the TGV from Gare Montparnasse to Rennes. From there, you can take one of four daily 90-minute bus rides to the island. The bus station in Rennes is at the north exit of the train station.

Bran Castle (Bran, Romania)

Most people know Bran Castle as Dracula’s Castle. Though its links to the fictional character are not as strong as much of the marketing material will have you believe, it’s still one of Eastern Europe’s most fascinating castles. The interiors may be slightly underwhelming, but the views and photo opportunities from the exterior and on the grounds are well worth the visit.

Bran Castle dates back to the late 1300s, and over the years, it’s served many different purposes, from a defensive structure through to a royal residence in 1920. The castle has only been open to the public since 2009. Today you can tour the fascinatingly eerie grounds and explore several rooms either with a tour guide or on your own – if you dare.

Insider tip: Keep an eye out for the deep dungeon that dates back to 1625 and the secret passageway.

How to get there: The nearest train station is in Brasov – a 3.5-hour train ride from Bucharest. Once there, you can take a bus or taxi to Bran. Buses leave every 30 minutes during the week and every hour on weekends.

Neuschwanstein Castle (Füssen, Germany)

Neuschwanstein Castle is one of the most recognizable castles in Europe, if not the world. This iconic 19th-century Romanesque revival palace in southwest Bavaria sees more than 1 million visitors each year. It started life as a rather lavish personal retreat for King Ludwig II of Bavaria, but it’s been open to the public since he died in 1886.

The views of the castle are almost more impressive than the views from the castle. Many tourists clamber up the surrounding hills or take a ride in the nearby Tegelbergbahn cable car to get those Instagram-worthy shots of its exterior.

Insider tip: If you’re after the best exterior views and photographs of the castle, consider taking a ride in the cable car, and planning a trip around spring, when you may be lucky enough to have perfect weather and the perfect backdrop of snow-capped peaks.

How to get there: Take the train from Munich to the town of Füssen. There, you can take bus 78 to the base of the hill in Neuschwanstein (get off at "Hohenschwangau Neuschwanstein Castles, Schwangau"); however, you need to climb up the hill to reach the castle. If you don't fancy a steep climb, take the cable car to admire the view above the castle. 

Europe is packed full of the most spectacular and unique castles, and you can get close to many of the most inaccessible of these by train. There’s no better way to journey back in time than by spending a day walking through ancient castle grounds or admiring stately living quarters from a bygone era, so be sure to include at least one iconic castle in your next Eurail trip.
