This is the river in the middle of the city, done on foot: the gold-roofed Národní divadlo, a café full of ghosts, and two green islands you can walk onto and stand in the Vltava with the castle laid out across the water.
Start at the National Theatre — the building Czechs funded by public subscription, watched burn down in 1881 weeks before opening, and rebuilt within two years out of sheer collective will. The gold letters read Národ sobě, the nation to itself. Across the street, the Café Slavia: writers, dissidents, Havel, and a window table that frames the river and the castle. Sit. That's the instruction.
Then onto the water. Slovanský ostrov — Žofín to locals — is a small park with a concert palace at its heart. Past the Mánes gallery on its functionalist legs over the weir, cross under the Legion Bridge to Střelecký ostrov and walk to its downstream tip, where the theatre, the castle and the foaming weir line up at once.
End in Malá Strana at Újezd — the tram, the Petřín funicular, or the bridge back at dusk with the theatre lit.
