We asked millennials and Gen Zers for their top hidden-gem travel destinations. Here’s what they said.

Bratone couldn’t get enough of Ko Lanta, an island off the west coast of Thailand dotted with palm trees and golden sand beaches.

“Super peaceful, beautiful beaches, very friendly people, and the best Thai food, as you’d imagine,” he said.

“Also very cheap. It was like $3 for a full meal,” Bratone added. “That’s like the streetside cafés, not a fancy place, but it was still very good.”

Nguyen is from Vietnam and recommended Sơn Đoòng Cave, nestled at the heart of Phong Nha-Kẻ Bàng National Park in the Quang Binh Province.

“It’s the biggest cave in the world,” she added of Sơn Đoòng, which stretches over 5 miles, encompassing vast caverns, underground rivers, and a plethora of stalagmites and stalactites.

“It’s really gorgeous,” Muthia said of her time in Labuan Bajo, a city on the Island of Flores in Indonesia. “I really love it there.”

The port city is known for its natural attractions, like the marine cave Gua Rangko, as well as boutiques, hotels, and beach clubs. It’s also considered a jump-off point for those wanting to visit Komodo National Park, a collection of islands and coral reefs home to a wide variety of species, from sea turtles and dolphins, to — yes — Komodo Dragons.

During a trip to Slovenia last April, Miñano — who’s from Spain — visited the Black Lake, one of 10 bodies of water nestled throughout the Triglav Lakes Valley. At the time, he remembers the mountains surrounding the lake being capped with powder-white snow.

“There is a church in the middle of the lake, and it’s so beautiful,” he said. “Not many people know it, I think at least here in America.”
