Is there a train that goes directly from Cascais to Sintra
We end a bicycle trip in Cascais and want to go to Sintra next.
We were offered a free transfer from Caiscais to Lisbon airport (not the city of Lisbon) and don't know if it is easier to leave Caiscais via this transfer to the Lisbon airport, and then take a train from the airport to Sintra.
Or should we just take a train from Cascais to Lisbon , and then a train to Sintra?
Thank you,
Lee
