Flights & getting there
Anek ferries call in at Diafani’s small jetty twice a week on route to/from Pigadia, Halki and Rhodes, and three times weekly en route to/from Pigadia and Kasos (€4, one hour). One of these continues to, or returns from, Crete (€19, eight hours) while two other services head to/from Santorini (€27, 15½ hours). There are also day trips by boat to Pigadia in summer, as well as assorted excursions (from €10 per person).
Tourist coaches carry day trippers from the jetty up to Olymbos. Unfortunately for both locals and tourists, there's only one weekly bus to/from Pigadia, but in summer services can increase (via Olymbos).
