Two companies, BUDO (Bursa Deniz Otobüsleri) and İDO (İstanbul Deniz Otobüsleri) operate fast catamaran passenger ferries across the Sea of Marmara between Istanbul’s Kabataş docks and Bursa (map) in about 2 hours. Both are municipal companies owned by their respective city governments.

Each offers between 4 and 8 voyages daily in each direction, depending on the day of the week (Saturday has fewest) and season of the year.

There are snack bars serving snacks, sandwiches, hot beverages and soft drinks on board the vessels.

Buying Tickets Online
Important! If you buy your ticket online by credit card, you must have that same credit card and your PNR (ticket reservation code) with you at the dock to print your ferry ticket!

But you may not be able to reserve a seat or buy your ticket online—you’re required to have a mobile phone from Turkey or one of only a few other countries.

1. BUDO: Kabataş – Mudanya
Bursa Deniz Otobüsleri (BUDO) operates at least 6 voyages daily between Istanbul’s Kabataş docks and Bursa’s Mudanya docks. More…

The BUDO website shows seat availability, so even if you can’t succeed in making a reservation online, you can see if a voyage is already sold out. If it is not, you can try going to the Kabataş dock, ready to travel, 30 to 60 minutes before departure time. In most cases, you should be able to get on the boat.
