Tucked into a wooded valley where the Teplá and Ohře rivers meet, Karlovy Vary is the Czech Republic's most celebrated spa town — famous for its thermal springs, elegant colonnades and the annual Karlovy Vary International Film Festival. It's an easy, rewarding trip for UK travellers looking for something a little different from the usual city break: think gilded spa architecture, wafer-thin oplatky biscuits, Becherovka liqueur tastings and gentle walks through the Slavkov Forest. Flights to Karlovy Vary from the UK are straightforward to arrange once you understand the route options, and this guide covers everything you need to plan yours.
Late spring (May–June) and early autumn (September) offer the best balance of mild weather, thinner crowds and good spa conditions. July brings the film festival and the busiest, priciest week of the year, so book well ahead if you want to attend. Winter is cold but atmospheric, with Christmas markets and quieter colonnades, while summer is warm and lively but the most popular season overall. Use the When to book chart above to spot the cheapest months to fly.
Karlovy Vary Airport (KLV) itself has very limited scheduled passenger service, so most UK travellers fly into Prague Airport (PRG) and continue overland — it's the route we'd recommend for reliability and choice. Airlines including British Airways, easyJet, Ryanair and Wizz Air operate frequent direct flights from London Heathrow, Gatwick, Stansted and Luton, as well as regional airports such as Manchester and Edinburgh, with a flight time of around 2 hours to Prague. From there, comfortable coach services (RegioJet and FlixBus) or a private transfer take roughly 2 hours to reach Karlovy Vary. Always compare both the flight and transfer cost against any seasonal charter options into KLV using the price charts on this page.
Once you arrive, the town rewards slow exploration on foot. Highlights include:
Karlovy Vary Airport sits around 5 miles (8km) north of the town centre. There's no dense public bus network directly to the terminal, so taxis and pre-booked transfers are the most practical option for the short 15–20 minute journey; car hire is also available for those wanting to explore the wider Karlovy Vary Region.
UK passport holders don't need a visa for stays of up to 90 days in the Czech Republic, part of the Schengen Area, but you will need a passport valid for the duration of your stay (a UK driving licence or ID card isn't sufficient). The currency is the Czech koruna (CZK); cards are widely accepted, though it's worth carrying some cash for smaller cafés and spa treatments. A UK GHIC or private travel insurance is recommended for any medical needs while you're away.
Your allowance to Karlovy Vary depends on the airline and the fare you book. The table below shows typical long-haul allowances so you know roughly what to expect — always confirm the exact limits with your airline before you fly.
