Buses from Dubrovnik to Korcula leave Dubrovnik’s main bus station once a day at 15:00 hrs, arriving in Korcula at 18:15.
The bus goes along the Croatian coast towards village Doli in the vicinity of Ston – where the Peljesac peninsula is connected to the mainland. At this point, the bus turns left and drives along Peljesac to Orebic. Once the bus arrives at Orebic (a small coastal town on Peljesac, which is the closest to Korcula) it drives to the Orebic ferry terminal and embarks on the car ferry Orebic – Korcula (Domince).
