Have a ride at Port Vell Aerial Tramway. Port Vell Aerial Tramway is the 1450-metre-long harbour aerial tramway with red cars connects Montjuic and Barceloneta. It starts in Barceloneta on the top of the 78-metre-tall 41.3731782.1877921 Torre San Sebastian tower, which has also a restaurant at its top accessible by an elevator. It has an intermediate stop at 41.3720832.1801211 Torre Jaume I tower (close to 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 line is Miramar at the slopes of Montjuic hill. Overall, the whole system is quite old (built in 1929, albeit restored a couple of times), and the car is packed with tourists during the daytime — particularly sensitive for a stroller or a wheelchair. But if you start from the Montjuic side, there are fewer people waiting.
