Decide per leg, because the answer flips. Prague to Brno is a clear win for rail: 185 to 210 kilometres with the fastest trains at two hours thirty-five. Prague to Český Krumlov goes the other way — the train needs a change at České Budějovice and takes around three and a half hours, while a direct bus does it in two hours fifty. Prague to Karlovy Vary is roughly two hours by road on the D6 against three or more by rail. Kutná Hora is the easy exception: 62 kilometres with trains in fifty-one minutes to an hour and ten, and more than forty a day.

Not by train, which surprises people arriving from other European capitals. Václav Havel Airport sits roughly fifteen kilometres west of the centre and has no rail or metro connection at all. The standard route is bus 119 to Nádraží Veleslavín and then metro line A, about forty minutes in total; the Airport Express coach runs direct to Hlavní nádraží in forty to forty-five; trolleybus 59 is the fastest surface option; and a taxi or car takes thirty to forty minutes. Have the data line working before you pick between them.

Yes for the city itself. A stay of three or four days covers the Castle and St Vitus Cathedral, Charles Bridge, Old Town Square and its 1410 Astronomical Clock, Josefov with the Old Jewish Cemetery and Spanish Synagogue, and Petřín. Five to seven days lets you add a second city without rushing — Brno is the easiest at two hours thirty-five by rail, while Český Krumlov and Karlovy Vary each want most of a day in transit if treated as day trips. Kutná Hora at fifty-one minutes is the one that comfortably fits a half day.

An overnight rewards it more. The direct bus from Prague is two hours fifty each way, so a day trip spends nearly six hours in transit and reaches the town at its busiest. Staying gives you the UNESCO old town inside its tight Vltava bend early and late, when the steep, dense lanes empty out, plus time for the castle with its round painted tower and eighteenth-century Baroque theatre, the Cloak Bridge and the Egon Schiele Art Centrum. Lipno reservoir is a further thirty to forty minutes if you want water.

Kutná Hora is the strongest by transport alone: 62 kilometres with trains in fifty-one minutes to an hour and ten and more than forty departures a day, which makes it a genuine half day rather than a logistics exercise. Karlštejn and Terezín are the other common choices. Karlovy Vary is doable at roughly two hours by road each way, but it earns its keep more as an overnight given the colonnades and the spa triangle. Český Krumlov at two hours fifty each way is the one most people wish they had slept in.

In reservoirs and lakes, and the season is short. Lipno in South Bohemia is the country's largest water body at roughly forty-eight to fifty square kilometres, with beaches and cycle paths and thirty to forty minutes from Český Krumlov. Slapy and Orlík on the Vltava sit south of Prague, Máchovo jezero further north, and the Brno dam serves the second city. Swimming is realistically late June to August at around twenty to twenty-three degrees. The spa towns are the year-round alternative, but that is drinking cures and thermal bathing rather than a beach.

Entirely, and this country gives you more chances than most to notice it. Prague's metro runs deep — Náměstí Míru is fifty-two to fifty-three metres below street level at the foot of an eighty-seven-metre escalator, and line A passes under the Vltava. The Blanka complex is about five and a half kilometres of urban road tunnel. The Moravian Karst tour is entirely underground, an hour long and including a motorboat leg on an underground river. Judge the plan at street level. If it still fails there, use Wi-Fi to reopen the plan's own setup guide, confirm the Czech profile is enabled and set as the mobile-data line, and give support the order reference and handset model.
