Portugal
Sintra is wonderful. If you have more time take the old tram from the terminus near the art gallery over to the coast - some good beaches there and a lovely run to them. Trams are infrequent, so plan!
Regular trains from Sete Rios station or Entrecampos station (Estação Rossio closed at time of writing)
