We loved Fiskardo. It's really relaxed. There are some lovely pebbly coves that you can take a refreshing dip in. Nightlife is bars and restaurants - I don't think you go there for clubs! Which is one of the reasons we liked it - you don't get your loud boozy element so that's refreshing. The fabulous Myrtos beach is nearby too and that is definitely a double plus.
This was our favourite beach. Lovely view from the top and lovely when you get down there. We went there lots!! Didn't experience the current that people have mentioned. The sea was lovely and turqoise and you could just float around - I loved swimming here more than anywhere else. The beach is quiet too which is good. We're going back this year!
