10 Best City Beaches in the World

What makes these the best beaches in the world? I think most people would agree that white sand, turquoise water usually makes the best beaches. In that case I'd say the best beaches are

1) Isla mujeres, Mexico

2) Zanzibar, Tanzania

3) Diani Beach, Kenya

4) Bora Bora, French Polynesia

5) Cook Islands, NZ

6) Whitsundays Islands, Australia

7) Islamorada, Florida

8) La Digue, Seychelles

9) Kho Lanta, Thailand

10) Nika Islands, Maldives

11) Virgin Islands National Park, US Virgin Islands

12) Castaway Island, Fiji

13) Santa Clara, Cuba

And places like that.
