From Lisbon :  Travelers landing in Lisbon can proceed to Cascais via rental car or train.  Many travelers opt for car rental, taking the A5 Highway which is the most direct route from Lisbon.  Some travelers who rent cars opt to take the EN 6 Highway instead because, though it takes longer, it offers the more scenic view between Lisbon and Cascais.  For a truly scenic view, travelers should forego the rental car and take the train which runs along the coast between the two locations.  Trains at least every 20 minutes, seven days a week, from Lisbon's Cais do Sodre station. The journey takes about 40 minutes, one-way fare is €2.30. Cais do Sodre can be reached from the airport by using the Aerobus or the metro
