Buses and trains are the two forms of shared public transport in Palma de Mallorca. The local buses are run by Empresa Municipal de Transportes Urbanes de Palma de Mallorca EMT and are very frequent. They have particularly good coverage of the beaches and the centre of the city. Timetables and fares are available from the City Council (http://www.a-palma.es/eng...). The main train system is operated by Serveis Ferroviaris de Mallorca SFM, Mallorca Railway Services.
The Palma City Sightseeing bus which is numbered line 50 on the EMT bus maps (http://www.emtpalma.es/EMTPalma/Front/imgdb/183.pdf) does a circuit of Palma that includes tourist attractions like Pueblo Español and major shopping centres like Av. Jaume III and Porto Pi, as well as the ferry and commercial ports. The buses are double-decker and the top floor is open air. A basic audio tour is free with the tickets. The tickets are €13 adults and €6,50 children for one day 24 Hours which is much higher than the other city buses, but they are valid for reboarding as many times as you like within 24 hours, and this is the only bus route that visits the Castell de Bellver. The Two-day fare is € 16,25 for Adults and € 8,13 for children from the age of 8 to 16. The first bus in the winter season starts from Cathedral at 10:00AM and the last bus in winter starts from the same place at 06:00PM.
