We'll be staying in Corfu Town in early July, and I'm curious about visiting one of the Diapontia islands, sometime between July 5-12 but we can be flexible on the exact day.
Which of these islands is the most interesting / beautiful / accessible? Are they really hard to get to? Is it possible to do a day trip or would we have to stay overnight? (In which case we'd have to scrap the idea.)
I have a guidebook but I fear it may be outdated. It says that there is a twice weekly ferry from Corfu Town and a daily connection with Agios Stefanos but would that be sufficient to allow for a day trip? Are there any organized boat trips like from Sidari? Based on their descriptions in my guidebook I think I'd be most interested in Othoni, but I'm also curious about Ereikoussa and Mathraki. Ereikoussa seems to be the most touristic of the three?
