i won't lie it's probably Greece for Zackyinthos island , it's beautiful there. really. In Asia the best beaches are probably in thailand , in Phiphiley/ phiphi island . That's the location of the famous "The beach" film (Leonardo Dicaprio) but i heard that the sand beach was destroyed by tsunami but it's still beautiful. And also G-Land , padang padang and bali , also Raja Ampat in papua nugini (indonesia)
Australia has some INCREDIBLE beaches, I love how there is lots of sand and they are very very gradually sloped in to the water so its not like you all of a sudden just dip down into it. also beaches in the caribbean, especially in the Virgin Islands are stunning and have pristine, crystal clear water and white, soft sand.
Crosby beach in England its not the warmest but it has great views and iron men.
Carribean and mediterranien.
