Florida's glowing waters among the natural wonders inspiring travelers in year ahead

Expedia has released its "Unpack '25" report identifying trends that provide insight into travelers' motivations for next year.

Vrbo, the vacation rental bookings-by-owner site, highlighted the "Phenomena List" trend as a theme for 2025.

Travelers are "seeking out awe-inspiring natural wonders, often planning entire trips around these events," a spokesperson from Vrbo told Fox News Digital via email about the trend.

The light is due to a type of chemiluminescence in which there's a chemical reaction within a living organism, according to National Geographic.

Bioluminescent waters have also been spotted on the West Coast, with visitors seeing bright waves on California beaches.

"The synchronous fireflies are a rare spectacle where thousands of fireflies light up in unison," said Vrbo. 

"This natural event occurs in May and June in the Great Smoky Mountains, drawing visitors from around the country."
