Following Rick's advice for taking a ferry from Ermioni to Hydra in mid-March, I went to the Hellenic Seaways site to check schedules. Site continually displays, "No Service" no matter what day is checked, even into June. Are they still in business? Is this a website problem? Should I just wait until arrival in Athens to check with a travel agency? If there is truly no more ferry between Ermioni and Hydra I will need to do some schedule rearrangement. Thanks!
I'm getting the same results you are, and I am clueless about what is going on.
I found a different website that shows sailing times (scroll down) for Hellenic Seaways ships, but I come up empty when I go to that company's website.
Hellenic Seaways is still in business but schedules may not be available just yet beyond Feb. 20. I know there are daily ferrys from Ermioni to Hydra throughout the year so it's possible the schedule is not available.
