Overview
Kaunas, Lithuania's second city, is a compact riverside gem where Gothic churches, Art Deco streets and a lively student population sit side by side. It's an easy, affordable city break from the UK — walkable, welcoming, and free of the crowds you'll find in Vilnius or the bigger Baltic capitals. Whether you're after a long weekend of café culture and history or a cheap base for exploring the Lithuanian countryside, flights to Kaunas from the UK are straightforward to book and typically excellent value.
Best time to fly to Kaunas
Late spring through early autumn (May to September) brings the warmest, driest weather and the longest days for sightseeing, with July and August the peak. Winters are cold and can be snowy, but Kaunas puts on a charming Christmas market in late November and December if you don't mind wrapping up warm. For the best combination of good weather and lower fares, aim for the shoulder months of May, June or September — see the When to book chart above for how prices tend to move across the year.
Airlines and routes
Kaunas Airport (KUN) is served by low-cost carriers popular with UK travellers, with Ryanair the main operator on routes from the UK, historically including London Stansted. Availability can vary by season, so it's worth comparing options using the price charts on this page rather than assuming a route runs year-round. Most UK–Kaunas flights are direct, taking around 2 hours 45 minutes to 3 hours; if you're flying from an airport without a direct link, a quick connection via another European hub is usually the alternative.
Things to do in Kaunas
Kaunas rewards a couple of days on foot, with most major sights within easy walking distance of each other in the Old Town and along Laisvės Alėja.
- Kaunas Old Town: Cobbled streets, the red-brick Kaunas Castle and a lively square full of cafés and bars.
- Laisvės Alėja: Europe's longest pedestrian boulevard, lined with shops, restaurants and Art Deco architecture.
- Ninth Fort: A sobering but essential museum documenting Lithuania's wartime and Soviet-era history.
- Pažaislis Monastery: A beautiful Baroque complex on the shore of the Kaunas Reservoir, a short trip from the centre.
- M. K. Čiurlionis National Art Museum: Home to the work of Lithuania's best-loved painter and composer.
At Kaunas Airport (KUN)
Kaunas Airport sits around 15km north of the city centre, near the town of Karmėlava. A public bus service connects the airport to Kaunas city centre and, less frequently, to Vilnius, with journeys taking roughly 25–40 minutes. Taxis and ride-hailing apps are readily available outside arrivals and take about 20 minutes into town, while car hire desks operate for those planning to explore further afield.
Top tips for finding cheap flights to Kaunas
- Book ahead but not too far: Fares on this route often sharpen up around 4–8 weeks before departure — use the When to book chart above as your guide.
- Fly midweek: Tuesday and Wednesday departures are usually cheaper than Friday or Sunday flights.
- Stay flexible on dates: Shifting your trip by even a day or two can unlock a noticeably lower fare.
- Compare airlines and airports: Check nearby UK departure airports as well as Kaunas against Vilnius, since combined search can reveal the better overall deal.
Travel essentials
UK passport holders don't need a visa for short tourist trips to Lithuania, which is part of the Schengen Area — a valid passport with at least six months left is all that's required, though an ETIAS travel authorisation is expected to become mandatory for UK visitors to the Schengen Area in the future, so it's worth checking the latest requirements closer to your trip. The currency is the euro (EUR), and cards are widely accepted, though a little cash is useful for smaller cafés and buses. No special vaccinations are required for UK travellers.
