Rent a boat in Agia Efimia - there are a few rentals, such as Yellow Boat - and spend the day visiting secluded beaches which can only be reached by boat.
There are a number of horseriding stables in Kefalonia and it is possible to arrange a ride into the mountains, through ruined villages and ancient vineyards, where the bells of the mountain goats and the cry of eagles are the only sounds to punctuate the silence. Gorgeous, and highly recommended, even in the height of summer.Go to the western corner and visit this remote village called Atheras and take a the road down to its private little beach with its century old monastary "Saint Spyridon"...tucked in time..
