Thanks for this.
Having looked at the website, there are some gorgeous beaches on the island. Some are difficult to get to and others are well known (Vai, Elafonissi etc.).
Plakias is listed as a popular tourist resort, which to be honest isn't the easiest place to get for holiday companies. it's certainly not the prettiest or most picturesque, it can get very windy in the high season (we see this as a bonus, others don't) and as far as the main beach is concerned (although considered to be a clean beach) doesn't even get into the top 20 on this website.
So taking into account these and other factors, one would question why Plakias is as popular as it is. It does though have a special 'feel' or vibe that it is difficult to put your finger on it. The people that live and work here are on the whole great but that doesn't tell the whole story as to why we go back time after time.
