Recently, more and more bike sharing projects have found their way to Rotterdam. The bikes can be found everywhere; In the park, in the Maas and randomly parked on the street. But are you looking for another alternative to discover the city, which will cost you less energy? You can take the tram, a solid 40 tons of steel taking you from one side of the city to the other, without losing sight of it.
Get yourself a day ticket at the RET-desk (Rotterdam Elektrische Tram) or RET-machines at the Central Station, also the start of your tour (check article: Kruisplein). From the total of 9 lines, 8 of them stop at the Central Station. The first one to take: Line 4 Marconiplein for a trip along the Nieuwe Binnenweg and Delfshaven (check article: Delfshaven) passing loads of spots. (check articles: UEB, Rotown and STEK). From Delfshaven hop on Line 8 Kleiweg and get out the Euromast for a walk through the Park and along the Westerkade to the Veerhaven (check articles: Westerkade and Veerhaven). At Willemsplein (Erasmusbridge) you can hop on Line 7 Woudestein and get out at the Noorderbrug. Cross the Zwart Jan Straat (check article: Noorderboulevard) on foot and get back to the Central Station using Line 4 Marconiplein along the Noordersingel.
This is of course just a suggestion. Combine the map of the network with the Spotted by Locals map in the App to make sure when to hit the stop button to jump on and off.
