In its “50 Best Eco Tourism Destinations in the World for 2026”, the publication highlights a major shift in travel behaviour, driven by growing environmental awareness and a desire for more meaningful, nature-based experiences. Backed by insights from TTW’s editorial team and more than 25 million readers, the report points to a booming sector expected to approach $1 trillion by 2035.

Portugal stands out

At the heart of this transformation is a move away from traditional luxury toward sustainability, conservation, and authentic local connection.

Among the global heavyweights—from the Yellowstone National Park to the Great Barrier Reef—Portugal secures its place on the list with Peneda-Gerês National Park, ranked 36th worldwide.

It is the country’s only national park—and a clear example of how ecotourism is being put into practice on the ground. Peneda-Gerês National Park is known for its rugged mountain landscapes, clear rivers and rich biodiversity, while also supporting local communities through small-scale, sustainable tourism. Visitors are drawn to activities such as hiking, wildlife observation and stays in traditional villages, all of which reflect a low-impact approach to travel.

A global shift in travel

The trend is clear. Destinations are being valued not just for their beauty, but for how they protect it.

From the Amazon Rainforest to the Galápagos Islands, the list showcases places where conservation efforts, renewable infrastructure, and local community involvement are shaping tourism models.

According to TTW, travellers are increasingly looking for:

• deeper connection with nature

• experiences that support local communities

• destinations that prioritise environmental responsibility

As TTW’s Editor-in-Chief Anup Kumar Keshan notes, travel is no longer just about visiting—it’s about contributing. That shift in mindset is what’s pushing eco tourism to the forefront of global travel decisions.
