I was at Lisbon Airport, last Sunday, and noticed at the Tourist Counter that Portuguese Railways, (CP) and the bus operator for the Sintra/Cascais area, SCOTTURB, are now offering a one day Euro 12 travel combi travel pass which allows one to take a train to either Sintra, Cascais or Estoril and use SCOTTURB buses to make connections between the Stations.
There are trains from Lisbon Restauradores to Sintra every 30 minutes at least and the same on the Line from Lisbon Cais de Sodre to Cascais. This offer the opportunity of a great day out.
I attach below a copy of an extract from the leaflet. (Click on it to enlarge:)
