Best Spa Towns in Czechia

Karlovy Vary is the one everybody has heard of, and it earns the reputation. The town is a long ribbon of pastel façades and colonnades stuffed into a narrow valley along the Teplá river, so the whole spa quarter is one continuous, gently uphill promenade. It's also the home of Becherovka, the herbal liqueur Czechs drink the way the French drink an aperitif — and the reason the town smells faintly of caraway and cloves in December.

The Mill Colonnade is the showpiece: a neoclassical colonnade designed by Josef Zítek and finished in the 1880s, long enough to house five separate springs under one roof, with a row of allegorical statues standing along the balustrade above it. Walk the length of it, tasting as you go. At the other end, the Hot Spring Colonnade covers the Vřídlo — the strongest thermal spring in Europe, which sends a jet of water up to a dozen metres high when the pressure is right. The water there comes out close to 73°C, which is why it's drunk in mouthfuls, not glasses.

The tradition is to buy a porcelain cup — a tall, handleless thing with a spout, sold at every kiosk in the spa quarter — and walk from spring to spring drinking as you go. Locals do it in bathrobes and slippers; you'll do it in trainers, and it's just as valid. Start at the hot end and work outward, because the springs get cooler and milder as you go, and the water is genuinely salty and rich. Two or three springs is plenty. A full tour of all of them is an experience in diminishing returns.

Above the town, the Diana Lookout Tower is the view you came for: a funicular climbs from the spa quarter through forest to a tower and a terrace looking down the whole length of the valley. Take it up, walk back down through the woods if your knees allow, and you've used a good hour. Getting here is simple — RegioJet runs direct buses from Prague Florenc in about two hours and fifteen minutes, comfortable, cheap and punctual, and they drop you at the top of the spa quarter.

Mariánské Lázně is smaller, greener and considerably calmer than Karlovy Vary, and for a lot of people that's the whole argument. Where Karlovy Vary is one packed street of colonnades, this one spreads its springs and colonnades out through parkland, with forest on the hills above and a restrained, English-park feel to the whole town. You notice the difference within ten minutes of walking: fewer tour groups, more people sitting on benches with a newspaper.

The town's signature is the Singing Fountain on the plaza in front of the Spa Colonnade — a wide, choreographed fountain that runs to classical pieces several times a day, and later into the evening in summer. It is a fountain, not the Sistine Chapel. But it works as the town's heartbeat and the natural place to agree to meet someone, and on a warm evening with the colonnade lit behind it, it's genuinely lovely.

The crowd is different too. Karlovy Vary draws international visitors and film-festival glitter; Mariánské Lázně draws spa guests — often Czech and German, often older, often staying three weeks rather than three hours. That gives the town a settled, unhurried rhythm that's pleasant to borrow. Getting here: a direct train from Prague takes about three hours.

That three hours is the honest trade-off. Mariánské Lázně has fewer headline sights than Karlovy Vary and asks more of you to get to, so it's a weak standalone day trip from Prague and a very good second stop if you're already staying in the region. It's also the town I'd pick if your plan is to do almost nothing for a day: a coffee, a walk into the park, a spring or two, a book.

Františkovy Lázně is the smallest of the three and, to my eye, the most perfectly preserved. Its centre is one coherent Empire-style design — low, symmetrical, pastel buildings arranged around a park and a colonnade — and because the town was never big enough to be worth demolishing, almost none of it has been touched by modern development. You notice that immediately: everywhere else in Czechia you look up from the historic core to see a panelák on the skyline. Here you mostly don't.

The springs here are cold mineral springs rather than Karlovy Vary's hot ones, and the town's speciality is peat and mud treatments — a different kind of cure, and one you'll see people walking to with an odd determined stride at eight in the morning.

Be realistic about scale: the whole core is a thirty- to forty-minute walk, and that's the honest version of a visit here. You don't come to Františkovy Lázně for a full day. You come for half of one if you're already in the region — it's a short hop from Mariánské Lázně by train or bus — for the colonnade, the park, a coffee in a town where the day-trippers never arrive, and the pleasant feeling of having found the quiet one.

These towns reward slow travel and punish a rushed day trip, and that's the single most useful thing I can tell you. They aren't a list of sights to tick off; the whole experience is the walking, the drinking, the sitting in a colonnade while it rains and the town goes about its business. Hurry through and you've seen some pretty buildings. Stay an evening and you'll understand why people came here for a season rather than an afternoon.

So: if you only have one day, do Karlovy Vary alone and don't try to add anything else. The colonnades, a cup of spring water, the funicular up to Diana, a long lunch — that's a full and satisfying day. If you have a free extra day, pairing Karlovy Vary with Mariánské Lázně makes a relaxed loop that's much better than either on its own, and it's genuinely one of the easiest good days you can add to a Prague-based trip.

Two practical things surprise people. Actual spa treatments — mineral baths, massages, the peat wraps — have to be booked in advance at a specific spa hotel, and the reception will happily tell you what's still free this week. But drinking the water and walking the colonnades costs nothing, needs no ticket and no appointment whatsoever. The cup itself is a modest one-off purchase, and the springs are open to anyone who can find them.

And please don't do it as a same-day return to Prague with a 21:00 bus home. I've watched people spend two hours getting here, four hours rushing and two hours getting back, then describe Karlovy Vary as "nice, very touristy". One night in a spa hotel changes the verdict completely — the towns in the evening, when the coaches have gone and the colonnade lights come on, are the reason this place has been famous for five hundred years.
