Common questions
How long is the ferry from Kos to Leros?
About an hour to an hour and a half on a Dodekanisos Seaways catamaran, or about two to three hours on a Blue Star conventional ferry. Catamarans run most days in summer; the larger ferries run a few times a week. Check current timetables, as they change by season.
Which port on Leros will I arrive at?
Catamarans usually arrive at Agia Marina on the east coast, while larger Blue Star ferries use Lakki, the big natural harbour on the west. The two are about 10 to 15 minutes apart by road. Check your ticket and arrange a taxi or transfer if needed.
Can I fly from Kos to Leros?
No direct flight exists. Leros's small airport has flights to Athens only, so flying between Kos and Leros would mean going via Athens, which is slower and far more expensive than the ferry. The catamaran, at about an hour to an hour and a half, is the practical choice for almost everyone, and the larger Blue Star ferries carry cars.
Can I visit Leros as a day trip from Kos?
Possible in summer if the catamaran timetable has a morning departure and an evening return. Check both directions before planning. Most visitors stay a night or two to see Leros properly, including its Italian-era architecture at Lakki and the castle above Platanos.
