Start early at Prague Castle, ideally arriving around 8:30–9:00. Enter via Pohořelec and walk downhill through Hradčany—it is quieter than approaching through the castle’s main ceremonial entrance. Allow about 2½ hours for St. Vitus Cathedral, the courtyards, and Golden Lane. The main complex opens earlier than some individual interiors; check the official schedule the evening before, and expect roughly 450 CZK for the standard circuit. Comfortable shoes matter, especially on the uneven stone and stairs.
From the castle, stroll to Nový Svět, one of Prague’s loveliest little surprises. This short lane of tiny historic cottages feels almost village-like, despite being minutes from the crowds. It takes only about 30 minutes, so linger for photographs rather than treating it as a quick checklist stop. Continue downhill through Hradčany and across Malá Strana to Lokál U Bílé kuželky for lunch; reserve if possible, as it fills quickly on Saturdays. Expect around 250–450 CZK per person for a filling Czech meal and a tank beer—try svíčková, schnitzel, or fried cheese, and note that the kitchen generally runs from late morning into the evening.
After lunch, spend an easy hour in Kampa Park, following the riverside paths and looking for David Černý’s playful crawling-baby sculptures. It is a good place for teenagers to slow down, grab a drink, and watch the boats rather than rushing between sights. Walk a few minutes onward to the Lennon Wall, where the colors and messages change constantly; be respectful of the surrounding residential lane, and bring a small marker only if permitted—the wall is regularly repainted and altered.
Finish with the climb to Petřín Lookout Tower in the late afternoon. From Malostranské náměstí, walk uphill through Petřín’s gardens; the funicular may be operating, but service can occasionally be suspended, so do not rely on it without checking. The tower usually closes earlier outside midsummer, and admission is approximately 220 CZK, with an additional charge or combined ticket depending on whether you take the lift. Allow about two hours for the ascent, panoramic views, and hillside paths. If energy is fading, take tram 22 or 18 from Malostranské náměstí toward the centre instead of forcing the full walk back.
Begin in Letná at the Národní technické muzeum, arriving around opening time—usually 9:00, but check the museum’s schedule before setting out, as hours can vary. Give yourselves roughly two hours for the spectacular transport hall, where historic cars, locomotives, aircraft, and motorcycles are displayed vertically through the museum’s huge atrium. It is especially good for teenagers because you can move between hands-on science, design, photography, and engineering exhibits rather than treating it like a purely historical museum. Admission is typically around 250 CZK for adults, with reduced tickets available; take tram 1, 8, 12, 25, or 26 to Letenské náměstí.
From the museum, walk through Letná Park toward the Prague Metronome—about 15 minutes, mostly uphill only slightly. The viewpoint opens dramatically over the Vltava, its bridges, and the Old Town rooftops, and the broad lawns are ideal for a short break. Allow 45 minutes, including time for photos and a relaxed wander; there is no entrance fee. Continue downhill or take a short tram ride toward Manifesto Market Florenc for lunch. Expect about 250–450 CZK per person, depending on whether you choose tacos, Asian food, burgers, or a drink; stalls and opening times change, so check the current listings on the day and bring a card, as cashless payment is common.
After lunch, stay in Florenc for the Prague City Museum, allowing about 1½ hours. The highlight is the enormous historic model of Prague, which makes the city’s medieval layout much easier to understand, while the interactive exhibits keep the visit lively. Check the museum’s current opening days and ticket prices before going—main exhibitions and temporary closures can change—and walk there from the market in roughly 10 minutes. Then take tram 3, 8, or 24, or walk around 20 minutes, to Kasárna Karlín, a former military barracks transformed into one of Prague’s most atmospheric cultural spaces. Its courtyards, cinema, event rooms, and casual bar make it a good place to slow down for an hour and a half; entry is generally free unless a specific event is scheduled, and refreshments are reasonably priced. Finish at Vzorkovna Dog Bar in Nové Město, reached from Křižíkova by metro line B to Národní třída, followed by a short walk. This underground-style venue is deliberately eccentric, with music, low-key rooms, and dogs wandering around; it suits an older-teen evening, but check the door policy and event listing, as entry and atmosphere vary. Budget roughly 200–400 CZK per person, and use the official Prague transit app or PID Lítačka for the return journey, especially if staying out after the metro stops running.
