Like Sandy, we don't do trips etc, but you can get a bus at a very unearthly early 7am to Corfu Town. Dead cheap. Did it once, but still in my nightclothes.... No comments please, forum.
Olga (Olga's Travels) who you can find at the crossroads near Amourada and Vasillis Supermarket will provide anything you want.
Sandy is right though - don't take the tour operators trips - book in the village.
