Things to do
Warsaw gathers around Castle Square: the Old Town rebuilt after the war, the Royal Route running south to Lazienki Park, and Praga on the far bank with a character of its own. Metro and trams cross the river, so choose a district by its evenings.
Old Town
Start on Castle Square by the royal castle and follow the cobbled lanes to the city walls and the Barbican. From there drop down to the Market Square with its rows of townhouses and the small chapel.
Lazienki Park
Lazienki Park, with the palace on the water, an amphitheatre and free-roaming peacocks, fills half a day. Enter from Aleje Ujazdowskie and work deeper into the park, returning along the canal.
Praga
Right-bank Praga keeps its tenement houses and factory buildings, now taken over by galleries and bars. Zabkowska street and the Rózycki market show the old trading quarter, cheaper in the evening than the centre.
Where to stay
Sródmiescie
Sródmiescie suits a first visit: the station, the Palace of Culture and the Royal Route are close. The district comes alive at night, and side streets can be noisy.
Powisle
Powisle by the Vistula is known for riverside boulevards and cafés under the bridges. The centre is walkable, and summer evenings happen down by the water.
Zoliborz
Zoliborz is a green district of interwar houses, gardens and quiet courtyards. It stays calm, with a tram or metro ride to the centre and the Old Town twenty minutes away.
Getting to and around Warsaw
Chopin Airport lies inside the city limits: buses and a suburban train reach the centre in about half an hour. Warsaw runs a metro and a dense tram network, while the Royal Route is better walked. Bridges cross the Vistula, and Praga is an easy tram ride from the old town.
Three days in Warsaw
Old Town and the Royal Route
Castle Square, the Old Town and the Barbican fill the morning. Walk down Krakowskie Przedmiescie to Nowy Swiat, then finish on the Vistula embankments.
Lazienki
A day in Lazienki Park: the palace on the water, the amphitheatre and shaded avenues. Return to Powisle in the afternoon and walk the riverside boulevards.
Praga
Take the tram to Praga for Zabkowska street, the Rózycki market and factory buildings turned into galleries. Cross back into the centre in the evening.
