The bus service on Corfu is reliable if infrequent. I have a feeling the service to Corfu Town runs about 6 times a day but someone will correct me if I am wrong. From Kassiopi you can also get a bus that runs up to Sidari via Acharavi and Roda.

There seem to be two sets of road signs for every junction now. One in Greek and one in English, so perhaps hiring a car wouldn't be such a problem now!

There is a bus service to Corfu town from Kassiopi so not quite sure if it's reliable, all buses to everywhere else on the Island leave from Corfu Town or did do when we were there in the 80's stayed in Sidari 2 years ago not many buses from there to elsewhere. As Corfu in places is now very English there are lots more road signs available suppose if you want to visit remote places a car would be adviseable.
We have stayed in Greece on several Islands from April/October and it's suprising how the weather can vary from year to year.
Have a great holiday.

Thanks everyone. A week isn't long, so what we do will depend on the weather. Starting to look forward now. It won't be long. I love Greece but have always gone late July and August. Oh we did go to Zante once in September and the weather in the main was lovely, with the evenings cooling down towards the end of the fortnight. I'd better pack a selection of suncreams with various factors as well - so much to remember! The Joys !

Take your driving licence anyway and hire a car for at least a couple of days in the middle of the week. The limited bus service will limit you so much that it is a shame to miss out on the many beautiful places there are to see.

Don't worry about getting lost...most people do ! And the maps!! It is part of the fun. You are never really lost in such a small island... you just take longer to get anywhere and come out in different places to what you expect. Most junctions on main (Ha! Ha! ) roads have signs in English anyway.
The north west coast is not to be missed and also the central areas of northern Corfu are worth a wander through (i.e.south of Acharavi).

Hire a car!

We stayed in Acharavi the last time we were in Corfu and we definitely got lost with a capital L. As I said previously we ended up in the hills and just drove non stop for a couple of hours. We stopped once to look at our map and were immediately set upon by a couple of young children who gave dirty balloons to our two children only to demand money in exchange. We then noticed their beggar mother lying in a shelter close by. She soon got up, but we soon hurried off again. This was a horrible experience. It hasn't put us off Corfu as it was a beautiful place. If it rains when we are there we will probably try our luck with a car once again.
