A day trip to Mathraki Island off the Northern Coast of Corfu takes you to a truly “away from it all” place. Beautiful beaches, a handful of Taverna’s and can be walked around in a few hours, with plenty of time to catch the ferry back to Corfu or have an overnight stop.
Ferry timetables from San Stefanos (NW) http://www.aspiotislines.gr./ . There are also other Ferries from other Corfu Ports depending on the time of year.
