Harbour Cable Car. Jun-Sep: 11AM-8PM. The 1450 metre long harbour aerial tramway with red cars connects Montjuic and Barceloneta. It starts in Barceloneta on the top of 78 metre tall Torre San Sebastian tower, which has also a restaurant on its top accessible by an elevator. It has an intermediate stop at Torre Jaume I tower (close Columbus monument), which can be reached by elevator from ground -107 metre tall tower, the second tallest aerial tramway support tower in the world. The final point of the tramway is Montjuic. Overall, the tramway is quite old (built in 1929), and the car is packed with tourists during the daytime--particularly sensitive for a stroller or a wheelchair. Currently, the Torre San Sebastian tower in Barceloneta is temporarily closed for renovation, while two other stops work as usual. One-way ?9.50, round trip ?12.50.
