According to the latest Phocuswright report, outdoor experiences are among the fastest-growing segments of the travel industry. In line with that, a TUI Musement study shows that half of respondents are interested in experiencing nature or taking part in outdoor activities while traveling.

Against this backdrop, TUI Musement, a leading provider of tours and activities, created a global ranking of UNESCO World Natural Heritage national parks. The ranking is based on the number of Google reviews these natural sites received***. The list includes ten destinations known for their exceptional scenic beauty, biodiversity, and geological diversity—from impressive waterfalls and dense forests to spectacular volcanic landscapes.

With more than 124,000 reviews and an average rating of 4.8 out of 5, Plitvice Lakes National Park in Croatia takes first place. This natural gem is famous for its 16 interconnected lakes, linked by numerous waterfalls and accessible via a wide network of hiking trails and wooden walkways.

In second place is Iguazú National Park in the Argentine province of Misiones, closely followed by the neighboring Iguaçu National Park in Brazil in third place. Together, the two parks form a cross-border natural area and share one of the world’s most impressive natural wonders. They were added to the UNESCO World Heritage List in 1984 and 1986, respectively. Their main attraction is the Iguazú Falls, with a total of 275 individual cascades plunging from different heights into the subtropical rainforest.

The Grand Canyon National Park ranks fourth with more than 63,000 reviews. From numerous viewpoints, visitors can enjoy spectacular views of the immense rock formations and cliffs shaped by the Colorado River over millions of years. Helicopter tours are especially popular, offering unique aerial perspectives.
