Experience one of the city's romkocsma, or 'ruin bars', dilapidated old buildings that have been turned into bars featuring upcycled furniture. Szimpla Kert is the oldest and most famous, with live music a few nights a week, and a flea market during Sunday daytime.

Soak up the natural minerals at the historic Széchenyi Baths, where you can enjoy an impressive assortment of thermal pools. There are also saunas and steam rooms.

Looming over Budapest, the 19th-century lookout tower of Fisherman's Bastion gives the best views of the city. If the walk up to the top of the hill on which it sits is too daunting, just hire an electric scooter to get you there – Budapest has plenty of companies renting them out.

Highly photogenic and understandably popular as a wedding venue, the Art Nouveau Modrý kostolík – commonly called the Blue Church – is well worth a quick detour to the east of Bratislava's old town.

Standing proud above the old town, Bratislavský hrad (Bratislava Castle) is a huge white building dating back to the 17th century. It's well worth a visit, not only to see the Baroque castle and admire the city views, but to explore the Slovak National Museum which is housed here.

Explore the Staré Mesto district, Bratislava's old town, to see some of the city's most picturesque historic buildings including the Medieval Michael's Gate. The main street, Obchodná, is lined with shops and cafés, and there are some great bike routes which will take you past key spots – the Old Market Hall, Ganymede's Fountain and bridges across the Danube.

Treat yourself to an unforgettable experience by watching the Wiener Staatsoper (Vienna State Opera) perform at the Vienna Operahouse. The stunning building hosts 40-minute tours, and of course you can take a look at the schedule and book tickets to a show while you’re in the city. 

A popular and historic café frequented by Freud and Trotsky, Café Central is the embodiment of Vienna's coffee house culture. Enjoy an Apfelstrudel while admiring the majestic interiors and listening to the strains of piano music.

Pay a visit to the Schönbrunn Palace. The Habsburg’s residence’s huge size has to be seen to be believed; the building contains over 1440 rooms! The adjoining classical gardens are just as impressive.

The City Museum of Ljubljana tells the story of the city from prehistory to the modern day, while the National Gallery of Slovenia showcases Slovenian and European art, including works by the Slovenian Impressionists. 

A medieval fortress, Ljubljana Castle sits atop a hill overlooking the city and offering stunning views from the towers or ramparts. The castle hosts events and has two restaurants to enjoy, and offers a fun, escape room tour, where each room becomes a game. You can reach the castle on foot, or by funicular railway. 

See Ljubljana from the Ljubljanica River on stand-up paddle-boarding tour. You can choose from a tour that will take you through the city to admire the castle and all the sights of the town, or if you'd like to immerse yourself in nature, you can do a tour of the Ljubljana Marshes Nature Park.

Take a stroll through the Gornji Grad (Upper Town) for delightful medieval buildings. Make sure to stop by St. Mark's Square, the Church of St. Mark, and the Museum of Naïve Art (Muzej Naivne Umjetnosti). Another highlight is the traditional lamplighter, who takes to the streets at dusk to light the authentic gas lamps. 

Visit Jarun Lake, a recreational area located southwest of Zagreb's city centre, also known as the 'Zagreb Sea'. The lake offers numerous activities, including swimming, paddle boating, and cycling, and at night turns into a nightlife hotspot.
