Hi Neill, I just published this in the other post Car Hire and Driving,
Here is a copy which may help you.
Driving - I have re-produced below, some driving info I published a while back - good tips!
It's the route from Airport to S S - but the principle holds firm for driving anywhere in Corfu.
The trick in Corfu is to plan routes via villages. Get a Map and Drive "Village to Village - then next village" following the road on the map, until a junction,
then note next village on your route, and you won't get lost!
The route below is a good example;
There is two, even three alternative routes the taxis/Coaches take you these days from the Airport to SS.
1) My favourite via Arrilas. Quickest and reasonable journey.
2) Via Sidari and avliotes - slightly longer but better sign posted, some narrow villages and bendy narrow mountain roads.
3) follow main road following signs for initially, Roda and Sidari, (by-passing) Roda, via Karoussades, Sidari Avliotes.
I'll stick with these.
Leave the Airport, at "T" junction turn Right, (you should have a map from the hire Co.) you need to take a left turn and go ahead -
To complicated to give exact directions, find your way out of town looking for Gouvia.
So - follow signs for Gouvia , then Limni.
you are heading for the road (that passes the road towards the Harbour - on your right)
It's a dual Carriageway (not many of those on Corfu) -
and also on your right you will note you are running along the coastline for a while.
After Limni, look for Gazatika (and general signs for Sidari & Palaiokastritsa) - you will turn right at a big "T"-junction).
At this "T"-junction (it should be signposted Sidari & Roda), turn right - then after 30 metres, the road goes sharp left & you will be driving up a "mini-mountain" one of the higher points of Corfu, and by-passing Skripero (on your left), through Troumpettas village (top).
As you descend the other side, after the double bends, (just before Kastellani village), there is another "T"-Junction sharply to the right, {this is the way the Coaches Go} (option 3)
Now decide your route!!
Option 1). You would not go right at the T"-Junction, carry on straight through Kastellani village, and turn right at the next "T"-Junction.
(Sign-posted Agros & Sidari).
At Agros village, Turn very sharply to the left (not towards Sidari), and follow the road, (follow signs for Arillas ), via Aspiotades, Manatades, Dafni, Termenades, Armenades, Kavadades, (by-pass)-Magoulades (on right) - drive into Arillas -
at "T" junction (Cash Machine - before sea front) turn right - Follow Road up hill, turn left, (before BP Garage),
Follow main Road, Turning right at next "T"-Junction, follow road - welcome to San Stefanos!
Option 2). Again, You would not go right at the T"-Junction, carry on straight into Kastellani bear right and simply follow signs for Sidari, then as below from Sidari.
a harder route roads not so good.
(option 3) - Starting back to descending the mountain, Turn sharp right, at the "T"-Junction, (just before Kastellani village),
{this is the way the Coaches Go}
it's much longer, distance & time, but better roads. It goes via the road to Roda initially, then Sidari, follow signs for Acharavi, (by-passing) Roda, via Karoussades, Sidari, Avliotes then into San Stefanos.
Sidari is partially one way system now - follow road through Sidari - as you leave Sidari 1/2 Kilometre, turn Left then immediately turn right after 30 metres. (straight on is sign-posted Peroulades). Follow signs for Avliotes, watch out for sharp bends, slowly through village, then follow main road to left for San Stefanos. 10 mins drive now.
This is probably your easiest route, road wise, but a much longer drive.
