The world's second best beach

You have to applaud the imperative behind 'County Donegal in 5 days' on the www.ireland.com website. It's part of their series, Ireland itineraries > Wild Atlantic Way.
However, it's a let down. It's clearly been put together by someone well-meaning, but who's working mainly off the web and making a dog's dinner of it.
More on that anon. In the meantime, got the chance to check out one of those statements which are repeated so often and in different ways that you wonder how it all began. It's Ballymastocker Bay, which we're often told has been described as the second-best beach in the world. Who did it, and when?
This from 'County Donegal in 5 days' http://www.ireland.com/en-gb/itineraries/wild-atlantic-way/donegal-in-5-days/ -

On a less epic scale, Fanad is fringed by the “most beautiful beach in the world”, according to one British journalist…and it can be found near Portsalonat Ballymastocker Bay.

Turns out it actually comes from The Observer on January 3, 1993 -

Can't find the details on what was the best one! (somebody said somewhere in the Seychelles . . )
