I loved Englishman's bay in Tobago, it is so very picturesque and a true lost paradise. But I'm keen to know what is considered the top 10 so wanted to start up this discussion. It may be a beach has a great bar or is just isolated and you are the only one there !
What are your criteria also for deciding what makes a great beach. I think these days the Caribbean has some of the best beaches in the world.
