How to Visit Us...
In all case please arrange it with us in advance. We can give you up to date directions, meet you at Faro airport or Tunes station
or just guide you in by mobile.
By Plane and Car...
Fly into Faro or Lisbon. Allow about 1 hour to drive from Faro, about 2 - 3 hours from Lisbon depending on time of day.
Take the A2 motorway (tolls up to about 20 euros) to the Algarve.
Exit at Castro Verde (also signed for Ourique).
Then take the IC1 from Ourique to S. Marcos da Serra, (about 25km). Exit at S. Marcos and head for the village.
If you miss the exit at Castro Verde do not take the next exit but come off at Messines and follow the directions below.
Take the motorway (Via Infanta) towards Portimao (opposite direction from Spain).
When you are on the the Via Infanta you can join the A2 signposted Lisboa for one junction exiting at Messines (toll about 1 euro 50),
or you can stay on the Via Infanta until the next exit signposted Lisboa, IC1 (which has no toll). The IC1 is not dual carriageway but
is usually not too busy.
The IC1 goes by Messines (where you can join from the A2) and continues north a further 10km to S. Marcos da Serra. Exit and pass over
the IC1 on the bridge and head for the village of S. Marcos.
From S. Marcos da Serra...
The road from the IC1 passes the station and heads a further 1km into the village. At this point it is essential that you contact us
for detailed directions to our site. If you go up the hill and turn sharp left at the top you will find the Cafe Central opposite the church (signposted "Igreja").
We can meet you at the cafe.
The inter-city "Alfa-Pendula" service from Lisbon (pre-booked tickets only) stops at Tunes, about 20km south of us. Either take a taxi or arrange for us to collect you.
The inter-regional stops at more stations including S.Marcos da Serra. The station is about 3km from us. There are not usually taxis around so arrange for us to collect you.
Sintefex Audio is based in the well known Algarve area in the south
of Portugal, an area surely destined to be the 'California' of Europe.
It already has the climate and it is growing its high tech industry at
an increasing rate. The Algarve is well known as a tourist centre but here
an ideal environment exists for research and development and it is a perfect
manufacturing centre for Europe and world. Despite being a recent member
of the EU the infrastructure benefits from fast communications with the
rest of Europe by air, by a new motorway network and by electronic means
with a full digital telephone system and ISDN links. Most shipping services
(for example DHL, our recommended operator) operate a standard 48 hour
service between us and the US and Europe.
Sintefex Audio is located approximately 50 minutes by main road from
Faro airport. Faro is 150 minutes by air from Paris and London, 180 minutes
from Amsterdam, Frankfurt, Munich and Milan. We are within 2 hours by road
of Lisbon, capital of Portugal, and within 3 hours of Seville in Spain.
Seville provides major rail, road and air links to Madrid and all Spanish
territories. Lisbon provides further access to Europe, the US and South
America with New York about 6 hours away.
Because Portugal is a member of the Shengen agreement on a common border,
transit to and from most European countries including Germany, Spain and
Holland is free of passport control making it an ideal trading partner
for non-Europeans who are fed up with airport form-filling and holdups
when travelling around. Portugal has adopted the Euro as its currency further
easing trade between Europe and the rest of the world.
