Leg 4: Amsterdam, Netherlands to Copenhagen, Denmark
Lowest cost: $49-$53
Fastest time: 12 hours, four minutes
This bus ride is an overnighter, and hopefully the sun will be up by the time you hit the Fehmarn ferry, an epic 45-minute boat ride across the Fehmarnbelt from Germany into Denmark. From there, you’ll pass through gorgeous Danish towns and sprawling countryside into Copenhagen. Book a bunk in advance at Urban House, the city’s hippest hostel (it has its own tattoo parlor) located in the also-very-hip neighborhood of Vesterbro. Nyhavn, Copenhagen’s waterfront entertainment district, is a good spot to end a day; it’s a gorgeous walk along the canal with no shortage of cozy bars and restaurants to duck into.
Don’t leave without: Seeing Tivoli Gardens, an old-fashioned amusement park with roller coasters, merry-go-rounds, and meticulously landscaped gardens set among classic European architecture
Leg 5: Copenhagen, Denmark to Berlin, Germany
Lowest cost: $20-$35
Fastest time: Seven hours, 55 minutes
There are a few different ways to book this leg. You can enjoy the Gedser-Rostock ferry, a scenic one-hour, 45-minute ride across the Baltic Sea, or take a longer trip that includes a few hours’ stopover in Hamburg. But the cheapest overnight route will have you in Berlin by 8:30am. Best to get an early start. This might be the most architecturally interesting capital in Europe — you’ll see brutalist Communist-era buildings set near Gothic, Baroque, and Roman structures. It’s also fun as hell and an absolute dream for travelers on a budget: cheap Airbnbs, cheap beer, free street art, beautiful parks, legendary nightlife, and young, English-speaking locals happy to show you around.
Don’t leave without: Losing track of time dancing your face off to a DJ set in the grungy back room of a warehouse building
Leg 6: Berlin, Germany to Warsaw, Poland
Lowest cost: $20-$23
Fastest time: Eight hours, 34 minutes
The bus leaves from either the Berlin Central Bus Station or Schonefeld Airport, so starting your journey with a flight to Berlin is also an option. Next stop is Poland, another one of those charming dirt-cheap countries that not enough Americans visit. In Warsaw you’ll find super-affordable digs and eats — even a fancy six-course meal can be had for a reasonable $70. There’s a long and fascinating history here; Warsaw has been marvelously rebuilt since its World War II occupation, and while trips to the Jewish section of town and the Uprising Museum show you exactly how far this city has come, nowhere showcases it better than Old Town.
Don’t leave without: Walking the cobblestone streets through the relaxing environs of Market Square and Castle Square to appreciate how a beautiful city can be so completely restored from ruin
Leg 7: Warsaw, Poland to Prague, Czech Republic
Lowest cost: $30-$38
Fastest time: Nine hours, 19 minutes
It’s a long road to Prague, with a trip through Dresden along the way, but it’s well worth it once you arrive at one of the most mind-blowingly picturesque cities on Earth. Europe’s “City of Spires” certainly has some grand architecture, and taking a day or two to inspect it all, along with Prague Castle, is definitely worth it. But Prague has also shot to the top of the European nightlife scene, so save some energy and get in on the action. For club goers, head to the nuclear bunker-turned-nightclub at Bunkr Parukarka. If dives are more your scene, head out to Zizkov, where 300 bars are packed into two square miles.
Don’t leave without: Walking across the incomparable 15th-century Charles Bridge — preferably at sunrise, when its ethereality isn’t lost in the throngs of tourists. Order some late-night smažený sýr (breaded fried cheese) off a food cart and have your fill of cheap Czech beer.
Leg 8: Prague, Czechia to Vienna, Austria
Lowest cost: $16-$22
Fastest time: Three hours, 55 minutes
Vienna ain’t cheap, but hanging here feels fancy and indulgent even if you aren’t dropping a ton of money. It’s classy, cosmopolitan, chock-full of attractive humans, and one of the most spectacular architectural cities in Europe. In particular, check out the Secession Building, an iconic example of Vienna’s turn-of-the-century art nouveau movement, and the popular Hundertwasser House, a quirky colorful apartment complex.
Don’t leave without: Vienna, once the seat of the Habsburg empire, is home to some of the most ornate palaces in the world, so be sure to hit up the Schönbrunn Palace, a one-time hunting lodge that boasts gardens on par with those at Versailles and is home to the oldest zoo in the world at Tiergarten.
Leg 9: Vienna, Austria to Bratislava, Slovakia
Lowest cost: $5-$7
Fastest time: 49 minutes
Because Vienna is often the airport of choice for those flying to Slovakia, there’s no shortage of cheap busses going from the Austrian capital to Bratislava (just make sure you take the bus to Most SNP station, not to the airport). It’s only a few minutes’ walk to the city center where you’ll find one of Europe’s best-kept secrets for divine food and laid-back vibes. This might be the most historically charming European capital you’ve never heard of. Colorful, classic old structures line the Danube, and Bratislava Castle stands like a sentinel over the city.
Don’t leave without: Browsing the shops at Eurovea, then walking along the Danube River into the historic old town center. Get some coffee and cake and take in the scenery.
Leg 10: Bratislava, Slovakia to Budapest, Hungary
Lowest cost: $13-$28
Fastest time: Three hours, 45 minutes
If you can, take the bus that leaves Bratislava at 10:20am; not only is it the cheapest, it also gets you into Budapest with enough time for a full evening in town. Spend it at one of Budapest’s famous ruin bars like Szimpla Kert, a former abandoned factory that has quirky themed rooms where old junk like bathtubs and car hoods serve as your bar stool. This city feels romantic and old-school, with jovial locals and plenty of Airbnbs to be found for shockingly little. Get a gorgeous panoramic view from the city’s highest point, Gellért Hill, an easy 30-minute climb on the Buda side.
Don’t leave without: Taking an afternoon to relax those travelin’ bones in one of the city’s natural thermal hot baths that date back 400-500 years. Day pass entrances start around $15.
Leg 11: Budapest, Hungary to Zagreb, Croatia
Lowest cost: $20-$26
Fastest time: Five hours
After a ride through rolling hills and charming little towns in Northern Croatia, you’ll arrive in Zagreb. Tourists usually skip Zagreb and head straight to the Adriatic Coast, which is a shame. Beyond the historic cathedrals and charming cobblestone streets of the old town, you’ll see a quirky mishmash of architectural styles and all the makings of a modern cultural capital — chic bistros, wine bars, jazz clubs, art galleries, counterculture bookstores, and specialty shops. Walk down Martićeva St and you’ll see what I mean.
Don’t leave without: Visiting the Museum of Broken Relationships, just one of Zagreb’s several offbeat museums. This one-time traveling exhibition is full of letters, gifts, and stories of failed romances, both heartbreaking and hilarious, and makes for an excellent quirky diversion.
Leg 12: Zagreb, Croatia to Rome, Italy
Lowest cost: $50-$65
Fastest time: 20 hours, 15 minutes
This trek is worth it for the spectacular mountain scenery in Slovenia that you’ll pass on the way to Milan, where you’ll have two hours in the evening to grab a bite. Think of that as an appetizer for the gastronomic delights that await you in the Eternal City. No worries if you blow your budget on heaps of fresh pasta and wine; Rome is basically an open-air museum of piazzas, fountains, and markets that are completely free to browse. This might be the one city in the world you’d never be able to finish exploring, and time is limited, so don’t waste it standing in line for the Colosseum. But you will want to brave the heavy tourist crowds to throw your coin in the Trevi Fountain.
Don’t leave without: Meandering through the Imperial Fora — public squares built by the ancient Romans that stretch from Vittoriano to the Colosseum and Constantine’s Arch.
Leg 13: Rome, Italy to Bern, Switzerland
Lowest cost: $59-$60
Fastest time: 19 hours, 25 minutes
After a hearty German breakfast during a two-hour stopover in Munich, you’ll see some nice mountain views and chalet-lined streets of small Swiss towns on your way to Bern. The picturesque Swiss capital is set on the Aare River against the towering Alps. If the weather craps out, there’s no shortage of museums here — two major art museums, an Einstein museum, and a communication museum. But if the weather is nice, you’ll want to wander down the banks of the Aare and take in all that majestic beauty.
Don’t leave without: Visiting the BearPark. The bear is Bern’s city symbol, and it pays tribute to these fierce behemoths with a large swath of land that runs along the Aare River, where you can watch the bears playing on the grassy hillside, bathing in the river, and hiding in their caves.
Leg 14: Bern, Switzerland to Paris, France
Lowest cost: $37-$46
Fastest time: 13 hours, 45 minutes
The first leg of this trip is absolutely gorgeous; you’ll ride along the shores of Lac Léman and through Geneva, stop for dinner in Lyon, then arrive in Paris at daybreak. (Just make sure you take the bus to Porte Maillot. Port Orleans buses cost twice as much, and busses to De Gaulle airport will leave you with an hour-long train ride into the city.) Head straight to the Latin Quarter — though it’s a bit touristy, it’s still packed with fragrant bakeries that will serve you the most impeccable croissant-and-coffee combination of your life. You can cross that off your Paris culinary bucket list; spend the remainder of your trip trying to knock off as many dishes as humanly possible.
Don’t leave without: Taking a stroll along the Seine. Paris can be overwhelming to do in a short period. If you’ve got limited time, take the Metro to the Eiffel Tower, get a nice long look at it (and the massive line to go up), then stroll along the Seine River back towards the Latin Quarter until you arrive at the Cathedral of Notre-Dame.
Leg 15: Paris, France to London, UK
Lowest cost: $27-$32
Fastest time: Seven hours, 30 minutes
And so your grand European tour comes to its close. If you’ve saved some money, celebrate with a pint in one of the city’s many venerable watering holes, or by burning your face off at a curry house. If you’re broke as a joke at this point, there’s plenty to do in London for not that much money.
Don’t leave without: Jumping on a double-decker bus tour. As one of the most historic cities in the world, picking between the changing of the guard at Buckingham Palace, a stroll through Piccadilly Circus, or selfies of you pushing over Big Ben can be a tough decision. So if you’ve got limited time, you can knock out Buckingham Palace, the Tower of London, Westminster Abbey, the Eye, and all the other sights you’ll be expected to post pictures of in one swing. After a journey like that, you’d be forgiven to do things to easy way.
