(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."
Only two more of 2014's top 10 islands appear on this year's global list. Ko Tao, Thailand, gained five spots this year, moving up from No. 10 last year, while Bora Bora dropped from No. 3 last year to rank ninth.
Here are the world's top 10 islands for 2015:
1. Providenciales, Turks and Caicos
2. Maui, Hawaii
3. Roatan, Honduras
4. Santorini, Greece
5. Ko Tao, Thailand
6. Madeira, Portugal
