Take the A1 NORTE from Lisbon airport. Follow the signs until you see A8 OESTE. Take the exit towards A8 OESTE (Attention – double exit: be careful not to take the A12 SUL – PT. Vasco da Gama, which would lead you to a 14km high-way bridge over the river Tejo into the opposite direction).
Once you’ve reached the tunnel stay at the far right and follow the sign A8 OESTE direction LEIRIA.
Stay on the A8 until the intersection MALVEIRA/MAFRA/ERICEIRA. Here you transit onto the A21 leading towards ERICEIRA. Leave the A21 at its final destination passing the toll station ERICEIRA!
At the adjoined roundabout you take the second exit towards RIBEIRA D’ILHAS – after passing two smaller roundabouts (always direction Ribeira d’Ilhas) you’re already on the coastal road N247 heading north.
Leaving Ribeira d’Ilhas (a famous beach-break) behind you pass the town of RIBAMAR. Rolling down the hill you will see the town sign SÃO LOURENÇO on the following ascent.
Keep going uphill until you’ve reached the end of the town, where you’ll see a bus stop on your left side. Opposite – right handed – you’ll see a big sign pointing towards CASAIS DE SÃO LOURENÇO.
Turn right and follow the street for approx. 50m.
Now you find yourself in front of a big white and blue house with columns and a parking lot in front of it – CONGRATULATIONS! You’ve made it!
Some quick notes regarding highway toll:
Don’t use the green lines (Via Verde) at the toll stations! These are reserved exclusively for cars with yearly prescription and you will not receive a valid toll ticket but a ticket with a fine.
Time: approx. 45min
