Turquoise lagoons, powder-white beaches, volcanic mountains, tropical forests and spectacular coral reefs make the world’s most beautiful islands some of the most desirable travel destinations on Earth.
But with thousands of inhabited and uninhabited islands scattered across the world’s oceans, which ones deserve a place among the very best?
For this TopMost10 ranking, we use the results of the Travel + Leisure World’s Best Awards 2026 as our primary benchmark rather than creating an entirely subjective ranking.
More than 207,000 Travel + Leisure readers participated in the 2026 World’s Best Awards survey, casting approximately 661,000 votes across hotels, cities, islands, cruise lines and other travel categories.
The resulting island ranking combines some of the world’s most famous tropical destinations with extraordinary places known for wildlife, culture and dramatic natural landscapes.
From Zanzibar’s Indian Ocean beaches to the jungles of Koh Samui, here are the top 10 most beautiful islands in the world in 2026.
10. Zanzibar, Tanzania
Country: Tanzania
Region: East Africa / Indian Ocean
Best for: Beaches, culture, history and honeymoons
Zanzibar takes the tenth position among the world’s best islands in the 2026 ranking.
Located off the coast of Tanzania, Zanzibar combines the qualities of a tropical beach destination with centuries of African, Arab, Indian and European cultural influences.
The island’s coastline features stretches of pale sand bordered by warm turquoise waters, while traditional fishing villages and palm trees give much of the coast a distinctly tropical character.
But Zanzibar offers much more than beaches.
Stone Town, the historic heart of Zanzibar City, is famous for narrow streets, intricately carved doors, old merchant houses and architecture shaped by centuries of Indian Ocean trade.
The island is also known as the Spice Island because of its long association with cloves and other spices.
Travelers can combine beach days with spice-farm tours, snorkeling, diving, historic sightseeing and trips to smaller surrounding islands.
For travelers exploring the continent, Zanzibar belongs on the same itinerary shortlist as the destinations featured throughout our Travel & Tourism coverage.
Why Zanzibar Is Special

- Popular honeymoon resorts
9. Dominica
Country: Dominica
Region: Caribbean

The mountainous island is covered in lush rainforest and filled with rivers, waterfalls, hot springs and hiking trails.
Its nickname, the Nature Island of the Caribbean, captures its appeal perfectly.
One of Dominica’s most famous natural attractions is Boiling Lake, a flooded volcanic fumarole reached through a challenging hike in Morne Trois Pitons National Park.
The island is also an important destination for whale watching and marine adventures.
Dominica is particularly appealing to travelers who would rather spend their vacation exploring forests and waterfalls than remaining at a beach resort for an entire week.

Travelers can surf along the coast, take scenic train journeys through the mountains, explore ancient ruins and search for elephants and other wildlife.
That diversity makes Sri Lanka particularly attractive to travelers who want several different experiences during one trip.
Its beaches range from popular surf destinations to quieter stretches of tropical coastline.
Further inland, mist-covered hills and tea plantations create scenery that feels completely different from the coast.
Sri Lanka ranked eighth worldwide in Travel + Leisure’s 2026 island results.

Mahé, Praslin and La Digue are among its best-known islands.
La Digue’s Anse Source d’Argent is particularly famous for its granite formations, shallow turquoise water and tropical vegetation.
Seychelles also offers rich marine ecosystems and protected natural areas.

Visitors may encounter giant tortoises, marine iguanas, sea lions, penguins and numerous bird species.
Volcanic landscapes add to the archipelago’s unusual appearance.
Rather than being dominated by conventional beach resorts, much of the Galápagos travel experience revolves around guided wildlife encounters, cruises, snorkeling and conservation-focused exploration.
