The Country That Refuses to Be Just Prague

Most travelers land at Václav Havel Airport, spend four days in Staré Město, and leave thinking they've seen Czech Republic. They haven't. The country has three distinct regions - Bohemia, Moravia, and Silesia - each with its own wine culture, dialect, and architecture. Brno, the second city, is quieter and cheaper than Prague but has a real student energy around Masarykova University. Český Krumlov looks like a movie set but earns it. The Moravian wine region around Mikulov produces dry whites that barely make it outside the country.

Prague itself is genuinely beautiful, but it helps to know which parts. Josefov, the old Jewish Quarter, is worth the admission fees. Vinohrady and Žižkov, two neighborhoods just east of the center, are where people actually live - good restaurants, no tour groups, trams running every few minutes. The No. 22 tram is the classic route, climbing up through Malá Strana toward the castle. Take it once during the day and once at night.

Summer in 2026 means long days, festival season, and crowds around the Charles Bridge by 9am. Get there at 7. The light is better anyway.

Staying Connected Across Bohemia and Beyond

Czech Republic has solid 4G coverage in Prague, Brno, and most major towns. In rural Moravia or hiking areas like Bohemian Switzerland National Park, signal can thin out - but it rarely disappears entirely. Most cafes and hotels offer Wi-Fi, though it varies in quality.

Your home SIM will technically work here, but roaming charges from non-EU carriers can be punishing. Travelers coming from the US, Canada, Australia, or Asia often find a local or regional data plan makes more sense.

An eSIM is the cleanest solution. No physical SIM to buy at the airport, no hunting for a T-Mobile or O2 store in Prague 1. With eSIMMY, the process is straightforward: message us on WhatsApp, we confirm your device is compatible and that coverage looks good for your itinerary, then we send you an install link directly in the chat. Tap the link, follow the steps in your phone's Settings, and your data plan is active - before you board if you want. That means you land at Ruzyně with maps already loaded and your accommodation address ready to go.

If you're planning to use WhatsApp to stay in touch with people back home - or to coordinate with other travelers - a stable data connection makes a real difference. This guide on using WhatsApp abroad without paying a fortune is worth a read before you leave.

Still weighing whether an eSIM makes sense for your trip? Here's an honest answer to that question.

Three Things Worth Knowing Before You Go

TIP 01

Cash Still Matters More Than You'd Expect

Prague's tourist center has gone mostly card-friendly, but the moment you step into a local hospoda (pub), a market stall, or a tram ticket machine that's out of order, you'll want koruna. ATMs are common - look for ones attached to actual banks like Komerční banka or Česká spořitelna rather than the standalone machines in tourist areas, which often charge higher conversion fees. Dynamic currency conversion will almost always cost you more. When asked whether to pay in CZK or your home currency, always choose CZK.

TIP 02

Prague Public Transport Is Excellent - Use It

The metro has three lines: A (green), B (yellow), C (red). They intersect at Muzeum, Můstek, and Florenc. Trams cover the gaps the metro doesn't reach, especially in Vinohrady, Žižkov, and across to Smíchov. A 24-hour pass costs a few dollars equivalent and covers everything. Validate your ticket before you board - inspectors are plain-clothed and the fine is immediate and not small. Uber and Bolt both operate in Prague and are generally reliable for late nights or trips to the airport.

TIP 03

Day Trips Are Worth the Early Start

Kutná Hora is about 1.5 hours from Prague's Hlavní nádraží by direct train. The Sedlec Ossuary - a small chapel decorated with human bones - is the draw for most visitors, but the town itself and the Cathedral of Saint Barbara are genuinely impressive. Český Krumlov is further, around 3 hours by bus from Florenc bus station. Book the bus in advance in summer. Both towns get crowded by late morning, so an early start pays off. If you have a second week, the train south to Brno and then east toward Olomouc gives you a completely different side of the country.
