An amazing experience, it's like going back in time. They only sell the amount of tickets for the amount of seats there are, so trains will never be overcrowded, however, if it's full there's lots of people on board. Masks are still mandatory when riding between Palma and Sóller but lots of people just take them off once they're sat down. There is room at the end of each carriage for pushchairs, wheelchairs, suitcases etc. The journey itself goes through the back end of Palma where you can see the darker side of the city, then on to the fincas and olive groves at the base of the mountains. In to the tunnel for around 3 minutes with only the ceiling lights is a magical feeling but could be scary or unnerving for small children or anyone with claustrophobia. Arriving back in to the daylight is great as the train now stops at the top of the mountain with phenomenal views across the town. You can jump off and get selfies here but it does only stop briefly. Once the whistle blows, get back on quick! Definitely recommend this journey, including the tram ticket down to Sóller Bay, which is another amazing journey in itself. The cost for the train is €18 one way, €25 return and €32 for the whole package of all 4 journeys.
