Tram No 17 has worked the same line for ages. My grandma used it in the 70s and later. This line usefully crisscrosses the city, and if you’d like to get to know Prague better and from different perspectives, it is worth exploring from one end to the other.
I have to say that tram No 17 is pretty well known to tourists at its beginning because it crosses the main downtown along the Charles bridge. But no worries, it will not be full for the entire duration of your alternative sightseeing tour. Despite the popularity of the old trams, line No 17 only has modern trams with low-floor access made by local brand Škoda.
The tram takes 52 minutes to run its line. From Vozovna Kobylisy to Sídliště Modřany there are 36 stops. Mostly they lead along the Vltava river and true Prague’s highlights (e.g. National Gallery – The Trade Fair Palace, National Theatre, Stromovka city park, Kovařovic Villa, the masterpiece of Czech Cubism and many other points of interest).
Tram No 17 has two end stations – Výstavište Holešovice (drives only up to Stromovka) that serves a more frequent schedule through downtown or Vozovna Kobylisy. You will see the pleasing characters of districts, different architectural styles, go up to the hill, and see the forest in the suburbs.
Enjoy a twenty-kilometer ride and the view over Vltava River – both its relaxing and industrial part.
