Does anyone have a website for Ferries between Kos, Greece and Bodrum? Do they still run regularly through the month of October? Thank you.
http://www.feribot.net/feribot/?lang=en I expect that by October the ferries won't be as frequent as earlier in the season.
Besides the ferries there are also plenty of privately owned excursion boats that travel between Kos and Bodrum daily. The owners stand outside their boats in the harbor at the end of the day and sell tickets for the following days. These boats do take longer, usually more than an hour. The high speed hydrofoils will cross in about a half hour. I have traveled both ways and prefer the quick crossing. I wouldn't anticipate any problem for you in October.
