Sóller is a town located on the north west coast of Mallorca. It is set in a green valley surrounded by Mallorca's highest mountains. Much of the town is residential and agricultural: it is full of orange, lemon and olive groves. The resort area of Port de Sóller is four kilometres away and is much more tourist oriented.
The combined population of Sóller and Port de Sóller is 12 000. The town has a beautiful square and many of the buildings are of architectural interest.
Sóller is twenty kilometres drive north of Palma de Mallorca on route MA-11. You can either drive through the toll tunnel or go over the top of the Coll de Soller. Once you arrive in Soller, park your car and continue on foot, as the town's narrow streets are not conducive to driving.
The Ferrocarril de Sóller  train service runs between Palma's Plaza d'Espanya and Sóller six times a day between 8AM and 7PM. Tickets are €10,00 single and €17 return and can be purchased at the station half an hour before the train leaves. The train journey is slow, taking over an hour, but is scenic, with marvellous views of the mountains on both sides of the tunnel. Note that even in the lower seasons the train can be very crowded. The trains are very old-fashioned with outside viewing platforms at the front and rear of each coach. The line is narrow gauge.
TIB  operates several bus services to Port de Sóller. The IB-09 service operates between Palma and Port de Sóller; the IB-12 service operates between Peguera, Valldemossa and Port de Sóller; and the IB-15 service operates, except in winter, between Port de Pollença, Lluc, and Port de Sóller.
A tram service operates between the Sóller train station and Port de Sóller approximately every half hour between 7AM and 8:30PM. Tickets are €4 per journey and are available on board. Like the train service from Palma, the tram service is very crowded, especially before the last train to Palma leaves in the evening.
For bike lovers there are great tracks for both roadbiking and mountain biking. Please note that mountain biking is in rocky terrain so one needs to be experienced and ride a full suspension bike. The old road to the Sóller Pass (since the tunnel opened there are only a few cars on the road) is a magnificent ride on a road bike. There are approximately 50 hairpin bends if you cross the pass to the other end of the tunnel.
Walking the mountains is popular and local guides are available. Try Tramuntana Tours in Sóller, Calle de la Luna, 72 or Puerto Sóller, Paseo de Traves, 12. +34 971632423. firstname.lastname@example.org.
