( CNN ) Island-hoppers take note : Providenciales in the Turks and Caicos is TripAdvisor 's latest pick for the world 's top island . Providenciales climbed a rung from last year 's No . 2 ranking among the travel review site 's Travelers ' Choice award winners to bump Ambergris Caye out of the top spot . It was quite a tumble for the Belize island . Ambergris Caye held the top ranking on the TripAdvisor global islands list for two years in a row before dropping out of the top 10 completely this year . Why the disappearance ? `` It 's hard to say , as winners change from year to year based on feedback from travelers , '' said TripAdvisor spokeswoman Julie Cassetina . `` Similar to last year and 2013 , winning islands were determined using an algorithm that looked at the quality and quantity of traveler reviews and opinions for hotels , attractions and restaurants on each island gathered during a 12-month period .
