Ever dreamed of an island getaway but worried about your carbon footprint? Good news! You can still have your paradise without the side order of guilt. These sustainable islands aren’t just talking the eco-friendly talk—they’re walking it too, with impressive conservation efforts, renewable energy initiatives, and community-based tourism that actually benefits locals.
The Azores: Europe’s Best-Kept Green Secret
Floating in the middle of the Atlantic, Portugal’s Azores archipelago takes sustainability seriously. Like, really seriously.
What makes them special? These nine volcanic islands generate more than 40% of their electricity from renewable sources (mostly geothermal and wind). The local government has implemented strict tourism caps to prevent overtourism and protect their pristine landscapes.
Must-do experiences:
- Whale watching from São Miguel island (with certified responsible operators)
- Hiking the rim of Sete Cidades, a twin lake crater
- Soaking in natural hot springs at Terra Nostra Garden
Where to stay: Eco-friendly accommodations like Pico do Refúgio on São Miguel island, housed in a restored 17th-century building with its own organic farm and solar power.
Palau: The Island Nation That Makes You Sign a Pledge
Yes, you read that right. When you arrive in Palau, you literally stamp a pledge in your passport promising to protect the environment. How cool is that?
This tiny Pacific nation has banned toxic sunscreens, created the world’s first shark sanctuary, and designated 80% of its maritime territory as a protected marine reserve.
Must-do experiences:
- Snorkeling in Jellyfish Lake (where the jellyfish have evolved to be stingless!)
- Kayaking through the Rock Islands (a UNESCO World Heritage site)
- Learning about traditional conservation practices from local guides
Pro tip: Pack reef-safe sunscreen! The kind with oxybenzone and octinoxate is banned here.
Dominica: The Nature Island of the Caribbean
Not to be confused with the Dominican Republic, Dominica is aiming to become the world’s first climate-resilient nation. After being devastated by Hurricane Maria in 2017, they’ve doubled down on sustainable rebuilding.
Dominica boasts 365 rivers, dense rainforests, and is investing heavily in geothermal energy. Even better? Their tourism model focuses on quality over quantity, avoiding the mass tourism pitfalls of other Caribbean destinations.
Must-do experiences:
- Hiking to Boiling Lake, the world’s second-largest hot spring
- Swimming in Emerald Pool, a natural grotto beneath a waterfall
- Learning about Kalinago culture (the island’s indigenous people)
Where to stay: Try Jungle Bay Resort, rebuilt after the hurricane using sustainable materials and employing locals from surrounding communities.
Samsø, Denmark: The Renewable Energy Island
This tiny Danish island produces more energy than it uses—all from renewable sources. Wind turbines dot the landscape, and most homes are heated with solar power or biomass. The best part? The renewable energy infrastructure is primarily owned by the locals themselves.
Must-do experiences:
- Touring the Energy Academy to learn about renewable innovations
- Cycling through quaint villages and farmland
- Sampling local organic produce at farm-to-table restaurants
When to visit: Summer months (June-August) offer the best weather and longest daylight hours.
Fernando de Noronha, Brazil: Where Tourist Numbers Are Strictly Limited
This stunning Brazilian archipelago takes exclusivity to a new level—with a daily visitor cap and an environmental protection tax that increases the longer you stay! The result? Pristine beaches and incredible wildlife experiences without the crowds.
Home to spinner dolphins, sea turtles, and incredible diving spots, this UNESCO World Heritage site shows how tourism limits can actually enhance visitor experiences.
Must-do experiences:
- Snorkeling at Baía do Sancho (consistently rated among the world’s best beaches)
- Watching sea turtles nest and hatch (seasonal)
- Hiking to various viewpoints for jaw-dropping vistas
Good to know: Accommodations are limited and book up quickly, so plan well in advance!
How to Make Your Island Visit Even More Sustainable
- Choose locally-owned accommodations rather than international chains
- Eat at restaurants serving local, seasonal food
- Use reef-safe sunscreen (especially important for marine environments)
- Participate in beach clean-ups or conservation activities
- Take direct flights where possible to reduce your carbon footprint
