Although Lefkada is the only Greek island accessible by land (via a causeway first built in 500 B.C.E.), its main attractions are the incredible white-sand beaches Porto Katsiki, Kathisma, and Egremni, which are featured on countless Greek tourism posters. The annual Ionian Regatta starts in Nydri’s marina. Mild winds and a smattering of small islands with plenty of anchorages make this part of the Ionian ideal for inexperienced sailors. Strong gusts in the northern part of the island are a favorite among kitesurfers (who swoop above Agios Ioannis beach) and windsurfers (who whiz across Vassiliki Bay).
