The tram runs 3km between Sóller town's railway station and the port, taking about 20 minutes on a route that passes through the orange and lemon groves filling the valley bottom. The rolling stock is original — open-sided wooden carriages from the early 20th century — and the tram shares the road for part of the route, slowing for cars and pedestrians with a bell that sounds faintly ridiculous and entirely charming. It runs throughout the day from early morning to early evening, frequently enough that you don't need to plan around it.
The classic way to arrive at Puerto de Sóller is to take the narrow-gauge railway from Palma to Sóller — a 90-minute journey through the mountains with one dramatic tunnel — and then change directly onto the tram for the final leg down to the port. Done in sequence, it is one of the best rail journeys in Spain, and not because of speed. The tram on its own is worth a return trip simply to watch the valley from the window, especially in spring when the citrus is in flower and the scent carries through the open carriages.
