As I will be visiting Lefkada this summer a visit to the nearby smallish (!) island of Meganisi is also a must. Short walks on the island are described by Lance Chilton in his booklet Walks in Lefkada and Meganisi. Read more about and see more of the island at the municipality web site at http://www.meganisi.gr/EN/index.html. Refer to that page also for information about transportation (bus schedules) and access (ferry schedules).
