How do Český Krumlov and Karlovy Vary compare?
Both Czech towns sit a couple of hours from Prague but ask for very different itineraries. Český Krumlov is a tightly wrapped medieval gem — 12,800 people inside an oxbow loop of the Vltava, with the country's second-largest castle complex (after Prague Castle) climbing the bluff above five courtyards, plus the Egon Schiele Art Centrum and the painted Castle Tower for the postcard view. Karlovy Vary is the polar opposite — a Habsburg-era spa resort of 49,000 in western Bohemia, founded by Charles IV in 1349 around 80+ thermal springs. Spa-goers carry porcelain sipping cups shaped like little teapots and walk the 132m Mlýnská colonnade between drinking fountains, sipping each spring at prescribed intervals through the day.
Logistics shape the choice. Český Krumlov is 134 km south of Prague, reached by Regiojet or Student Agency direct bus in about 3 hours for around 220 CZK; no direct train. Karlovy Vary is 130 km west, also a 2-hour 15-minute bus from Florenc for around 180 CZK. Český Krumlov shines on castle interiors (Tour I and the rare Baroque Castle Theatre), the Egon Schiele Art Centrum, and summer Vltava rafting at 600 CZK for two hours. Karlovy Vary delivers the spa cure — 60-minute thermal baths at 800–1,500 CZK, the Becherovka distillery tour, the Diana funicular at 80 CZK, and the early-July film festival when the Hotel Thermal fills with directors.
Pro tip: Krumlov sells out every weekend July through September — book your guesthouse a month ahead and arrive Sunday afternoon when the Prague day-trippers leave, walking the empty cobblestones at dusk for the long-shadow castle photographs. Karlovy Vary gets quiet by 21:00 outside festival week, which is exactly the rhythm spa weekends ask for; Café Elefant on the colonnade does an old-school strudel for 90 CZK. Pick Český Krumlov if you want a Renaissance castle, painted facades, and a town that walks end-to-end in 30 minutes. Pick Karlovy Vary if 19th-century colonnades, mineral water rituals, and Becherovka tastings sound like the right pace.

🛡️ Safety
Český Krumlov
Český Krumlov is one of the safest tourist destinations in Central Europe — extremely low crime rate, well-policed historic centre, and a small-town atmosphere even at peak season. Violent crime against tourists is essentially unheard of. The main risks are practical: slippery cobblestones in wet or icy weather, occasional pickpocketing in the most crowded summer hours around the castle entrance, and the standard tourist-trap restaurants on the central square that overcharge.
Karlovy Vary
Karlovy Vary is one of the safest tourist destinations in the Czech Republic — extremely low crime rate, well-policed spa district, and a calmer atmosphere than Prague even at peak season. Violent crime against tourists is essentially unheard of. Main risks are practical: slippery paving stones around thermal springs (constant mineral deposits make them treacherous when wet), the sometimes-aggressive heat of the thermal water (can scald), and the steep climbing paths up to lookouts and the Mary Magdalene church.
🌤️ Weather
Český Krumlov
Český Krumlov has a humid continental climate similar to Prague — warm summers (20–28°C, occasional 30°C+ heat waves), cold winters (often below freezing, with snow December–February), and pleasant shoulder seasons in May–June and September–October. The town's position in a valley along the Vltava gives slightly higher humidity than surrounding hills and occasional river fog in autumn. Pack layers in any season; dramatic short-notice showers are common May–September.
Karlovy Vary
Karlovy Vary has a humid continental climate moderated slightly by its valley setting and the surrounding Slavkov Forest. Summers are mild (often cooler than Prague by 2–3°C due to the elevation, around 380m), winters cold and frequently snowy December–February. The thermal-spring microclimate keeps the spa district itself a degree or two warmer than the surrounding hills. Pack layers in any season; the spa promenades are exposed and the colonnades are open-sided.
🚇 Getting Around
Český Krumlov
Český Krumlov's historic centre is tiny and entirely walkable — most cars are banned from the historic streets, and the entire UNESCO area can be crossed on foot in 15–20 minutes. The bus station is a 10-minute walk from the centre; the train station is a less-convenient 20-minute walk uphill. There is no in-town public transport (and none is needed). For day trips to surrounding sights, regional buses and rented cars are the options.
Walkability: Český Krumlov is one of the most walkable destinations in Europe — the historic centre is small, traffic-free (mostly), and dense with sights. Bring sturdy shoes for the cobbles and steep ramps; otherwise no transport needed within the town.
Karlovy Vary
Karlovy Vary divides into two distinct areas: the spa district (lázeňská čtvrť) along the Teplá River — pedestrianised, hotel-rich, where you'll spend most of your time — and the modern lower town around the train and bus stations, 1.5 km north. The spa district itself is fully walkable end to end in 15–20 minutes; for the airports, train station, and Moser glassworks you'll need the city bus, taxi, or rideshare.
Walkability: The Karlovy Vary spa district is one of the most walkable historic centres in the Czech Republic — pedestrianised, dense with sights, and small enough to cross in 15 minutes. Bring sturdy shoes for the slippery mineral-coated paving around the springs. Outside the spa district, distances require buses or taxis.
