9. Trinidad and Tobago
If a sexy vacation is what you're after, you should start preparing for your upcoming trip to Trinidad in March. Carnival is one of the biggest festivals in the world and though there are Carnival festivals held all over the world, no one does it quite like Trinidadians. Every year on the Monday and Tuesday before Ash Wednesday, folks take to the streets to celebrate the festivities before Lent. Women dress up in elaborate costumes in which most of the material rest on their heads. If you can't make it to Trinidad during Carnival, no worries, the party lasts all year round.
