Things to do
Prague stands on the Vltava, and its historic core fits into a walk between Old Town Square and the castle district. The river cuts the city in two, while trams and the metro reach the districts beyond the tourist circuit.
Old Town
Old Town Square is almost empty early in the morning, and the astronomical clock can be studied without a crowd. Walk to Charles Bridge before ten, then turn into Josefov to see the old synagogues and cemetery.
Prague Castle
The castle occupies the hill above Malá Strana: St. Vitus Cathedral, the old royal palace and Golden Lane. Climb on foot from Malostranské námestí and come back down through Petrín park towards the river.
Vysehrad
Vysehrad sits on a rock above the Vltava with the basilica of Sts Peter and Paul and a cemetery of Czech artists and composers. The walls open onto the river, and quiet streets nearby keep the crowds away.
Where to stay
Staré Mesto
Staré Mesto puts the main sights within walking distance: square, bridge, shops and restaurants. Bars keep the nights loud and rooms cost more, yet travel time disappears and a tram is seldom needed.
Vinohrady
Vinohrady draws people for wide streets, restaurants and calm evenings among locals. The centre is ten minutes by tram, the same lines serve the main station, and bakeries open early on these blocks.
Holesovice
Holesovice across the river lives on galleries, cafes and a market inside old industrial halls. Sights are not next door, but rooms cost less and the bridges stay quiet in the evening.
Getting to and around Prague
From Václav Havel airport a bus reaches a metro station, from where the train continues to the centre, and the Airport Express runs straight to the main station. Trams are the main transport in the city, reaching Staré Mesto, Malá Strana and Vysehrad. The metro helps on longer runs, while the historic core is better covered on foot.
Three days in Prague
Old Town and Josefov
Start at the astronomical clock on the square, walk down Paris Street and step into Josefov. Return to the river in the evening and eat in the lanes around Old Town.
Castle and Malá Strana
Climb to the castle in the morning for the cathedral and Golden Lane. Come down through Malostranské námestí, have lunch in a trattoria and spend the evening by the river.
Vysehrad and Vinohrady
Ride to Vysehrad in the morning for the cemetery and the walls above the river, where both banks open up. After lunch move on to Vinohrady, where kitchens cook for locals rather than tourists.
