Top Islands in the World for 2025

From Koh Samui to Jamaica, Discover Immersive & Sustainable Island Getaways Redefining Global Travel

Island tourism is experiencing a powerful resurgence in 2025. With unspoiled beaches, rich cultural roots, and a shift toward immersive experiences, islands have captured the interest of modern travellers. The global appetite for meaningful, authentic island journeys is growing up by 30% year-over-year, reflecting a new era in how travellers plan, book, and experience island vacations.

This surge isn’t just about beaches and sunshine—it’s about connections, affordability, and sustainability. The islands featured in this year’s top destinations list are meeting those expectations head-on, making them ideal for B2B travel agents and consolidators creating tailor-made packages for evolving customer preferences.

New Island Trends for 2025: Authentic, Local, and Accessible

Gone are the days when islands were just luxury retreats for honeymooners or high-end tourists. In 2025, travel demand favours islands that deliver a strong sense of place, with cultural festivals, eco-stays, local food trails, and nature-based experiences.

What defines this year’s top islands is their ability to blend affordability with unique offerings, making them attractive to both FIT and group segments in the B2B space.

🇹🇭 Koh Samui, Thailand: Affordable Luxury with Tropical Charm

Ranking Highlight: Top for budget-friendly luxury & immersive Thai culture

Koh Samui has emerged as a global favourite for travellers looking for value without compromising on experience. Its blend of palm-lined beaches, world-class spas, vibrant nightlife, and lush landscapes offers a complete island escape.

With accessible international flights and high-value accommodations, it’s become a prime destination for travel agents targeting mid-to-high-tier travellers seeking relaxation with a dash of adventure.

Travel Tip: Promote curated add-ons like Thai cooking classes or island-hopping to upsell group packages.

🇯🇲 Jamaica: Where Culture Meets the Caribbean Coast

Ranking Highlight: Best for cultural immersion & local rhythms

Jamaica is far more than reggae and rum. In 2025, its rich cultural heritage—from the beats of Bob Marley to the aromas of jerk chicken—drives serious traffic. Travel agents can pitch Jamaica as an all-rounded experience combining beach beauty, vibrant cities, adventure excursions, and deep local flavour.

It’s an ideal match for clients seeking purpose-driven travel or incentive tours with culture at the core.

🇵🇹 Madeira, Portugal & 🇺🇸 Nantucket, USA: Underrated Island Escapes Gain Traction

Ranking Highlight: Rising U.S. outbound favourites with 45% booking increase

Mid-sized islands like Madeira and Nantucket are attracting interest from U.S.-based travellers in search of offbeat elegance. Madeira is beloved for its nature trails, wine tours, and Atlantic charm, while Nantucket offers New England’s coastal charisma with boutique luxury.

Both destinations are seeing a rise in MICE travel and eco-tourism, expanding opportunities for B2B packaging beyond the mainstream.

How Island Travel Is Shaping Global Tourism in 2025

Island tourism is now a key growth engine in global travel. Lesser-known island destinations are gaining visibility, pushing demand beyond traditional hubs. For B2B players, this means new revenue streams, especially in small-group travel, wellness retreats, and long-stay remote work packages.

With tourism comes economic opportunity. Islands like those mentioned are experiencing growth in jobs, investment in local businesses, and improved tourism infrastructure—all vital talking points when selling to institutional clients or pitching CSR-aligned corporate retreats.

Sustainability: The Core of Tomorrow’s Island Itineraries

The new traveller wants to explore—but not at the expense of the planet. Sustainability is more than a buzzword—it’s now a must-have filter for island selection. From banning single-use plastics to promoting eco-resorts and local guides, destinations that prioritise preservation are seeing repeat business and longer stays.

Jeff King of Virtuoso notes the shift: “More travellers are opting for low-impact journeys with strong community ties—this is the new luxury.”

B2B Travel Tips for Booking Island Experiences in 2025

• Plan in Shoulder Season: Rates can drop 30–50%, making it easier to offer a premium at better prices

• Bundle Smartly: Flight + hotel + activity packages boost margins and traveller satisfaction

• Push Local Tie-Ins: Culinary trails, cultural performances, and artisan workshops are high-converting extras
