Highway A8 and then A21 will take you to Ericeira:

1.    Leaving the airport on Av. Berlim, turn left on Av. Cidade do Porto and follow the signs towards highway E1 direction A1 Norte/A8 Oeste/A12 Sul;
2.    Take exit 14 on IC17/CRIL towards A8 Oeste – (that is roughly 700 meters after driving on the highway and passing the Burger King, on your right hand side, as well as passing underneath the highway bridge);
3.    Take the exit towards A8 direction Leiria/Loures and follow that road for 16km;
4.    Take exit 5 towards N8/Mafra/Malveira and follow the highway A21 until the end;
5.    After passing the toll take the 2nd exit at the roundabout, towards Ribeira Dílhas – follow the road that leads you downhill for roughly 1 km  (pass one more small roundabout) until you get to the big roundabout with a surfer riding a tube. You can already see the ocean from the roundabout,
6.    Take the 1st exist, towards the Casal do cardio (there is a sign indicating this name, which is the name of the neighborhood),
7.    Take the first left, on Avenida Colinas do Atlantico;
8.    Take the first right (uphill);
9.    Take the first left, that is already our road, Rua Maria Guiomar Carvalho Miranda. Go almost until the end of the road.
10.    We are on your right hand side, number 56 – there are lots of palm trees in the garden and we are the only house on our street with blue gates. Welcome!
The fee for the toll (for a car) is 2,90 Euro one way, make sure you don’t take the fast lane and always get a valid ticket at the ticket machine!
