Is it worth visiting Bratislava for just 1 day?+
Yes, and it's the most common way to visit. The historic centre is small, and the main sights — Michael's Gate, the Main Square, the cathedral and the castle — can be covered in 5 hours including lunch. Anyone wanting to add Devín Castle or the vineyards of the Malé Karpaty needs a second day. It also works well as a day trip by car or train from Vienna, without needing to stay overnight.
Do I need euros in cash, or can I just pay by card?+
Slovakia has used the euro since 2009, so no currency exchange is needed. Cards work almost everywhere, including public-transport ticket machines, small pubs and market stalls, and contactless payment is standard. Cash is handy at markets, at wineries in the Malé Karpaty hills, and for tipping. ATMs at the train station and around the centre accept foreign cards without trouble, but watch for the dynamic currency conversion offer at the till or ATM — always decline it and choose to be charged in euros.
How much is transport around the city, and do I need to validate my ticket?+
A 30-minute ticket costs €0.90, an hour-long one €1.30, and a day pass €3.80. Buy it from a machine at the stop, at a newsstand or through the IDS BK app. A paper ticket must be validated in the yellow machine on board before travel, or it counts as invalid, with an on-the-spot fine of €50. Plain-clothes inspectors mainly work the route to the castle and the airport line.
How do I get to Devín Castle, and is it worth it?+
By bus 29 from Nový most, running roughly every half hour; the ride takes 25 minutes and a standard city ticket covers it. It's worth it if you like views and history — it's the confluence of the Morava and Danube rivers, a Great Moravian hillfort, and a former Iron Curtain border post all in one place. The site itself is a ruin with no shade, so bring water in summer. In July and August a sightseeing boat also runs there from the riverfront.
Is Bratislava a cheap destination?+
Food and drink are moderately priced — a half-litre of beer costs €2–3.50, and a set lunch menu €6–8. Accommodation is noticeably better value: a 3-star double room runs €60–95 a night. Admission fees are lower and public transport is among the cheapest in Central Europe. Against Vienna, budget for roughly half the cost.
Will I get by with English?+
English is spoken in the historic centre, in hotels and by younger staff, but it thins out once you're away from the main sights, so a handful of Slovak phrases help: ďakujem (thank you), prosím (please), dobrý deň (good day). Slovak belongs to the same Slavic language family as Polish, Russian and Ukrainian, so travellers with any grounding in those languages will recognise plenty of words on signs and menus.
When is the best time to visit?+
May, June and September. In September and early October, add the grape-harvest festival in the Malé Karpaty, when wine cellars open up in Pezinok and Modra. July and August are hot in the Danube lowlands, with temperatures regularly above 30°C, and the old town's narrow lanes trap the heat; on the plus side the city empties out as locals head to the coast. December brings a Christmas market that's smaller and noticeably cheaper than Vienna's and is worth a weekend trip. January and February are the cheapest and quietest months, but the itinerary shrinks to museums and pubs.
Can I drive to Bratislava, and where do I park?+
You can, but driving into the old town creates a headache — the entire centre falls under the PAAS resident parking system, with hourly rates and enforcement. The most sensible option is to leave the car in the underground car park at Eurovea or Aupark in Petržalka, where it costs around €1 an hour, and walk across the bridge. An electronic vignette is compulsory on Slovak motorways, bought at eznamka.sk; a 10-day pass costs around €8, and it must be bought before you enter the motorway, not after.
