Lovely sea-side town 35kms from Lisbon. We took the aerobus from the airport to Lisbon center and from there direct train to Cascais as the bus to Cascais was unknown and no where to be found.
Given that it took 2.5 hours it would have been better to have rented a car. Definately recommend O Pescador seafood restaurant in the centre of Cascais (behind the fish market). Amazing meal and fabulous wine. Excellent value for money. I found it via the Conde Nast website and was not disappointed!
Excellent resort with great beaches, great park, lots of restaurants and very east access to Lisbon and airport
