"Describing them as a natural rock formation barely does them justice — the rivers of sand that sparkle at their feet, the bold blue sky just visible overhead, the rocks themselves," King said. "The rock formation's rust red curves ripple like a concertina. It's indescribable."

"Birgufest's beauty lies in its simplicity: lit candles across the city create a glittering illusion," King said. "Of course, this city's narrow cobbled streets and towering honeycomb walls look stunning all day long, but this is other worldly."

"From the earth, it is hard to see the sky; from the sky no-one can see the earth," King said. "But in the middle of those places, beneath a canopy of trees, visitors to eco-resort
Mashpi Lodge can cycle through the air, fully immersed in the impressive emerald beauty that lives beneath the treetops."

Alex Roddie, Sub-Editor of Sidetracked Magazine, told Business Insider: "The Cape Wrath Trail — Britain's toughest long-distance hike — is used as a Ministry of Defence training zone and must be accessed either on foot or by ferry, making it an unusual place to visit."

"The Jotunheimen National Park contains Norway's highest glaciated peaks," Roddie said. "On the edge of this wilderness, the DNT (Norwegian Trekking Association) cabin of Gjendesheim makes a comfortable base from which to explore the mountains or kayak along the magnificent Lake Gjende."

"This high mountain village in the Swiss Alps is a quieter alternative to the mini-metropolis of Zermatt nearby, yet is surrounded by some of the finest peaks in the Alps," Roddie said.

"The Cairngorms form one of Britain's highest and most remote mountain areas — a haven for rare plants and animals and a Mecca for mountain-lovers, Roddie said. "A classic multi-day walk links Braemar with Aviemore through this glen, and is a must-do for all Scottish backpackers."

The eco-hostel has an 85-year history and is located on the edge of the remote and beautiful Ben Alder area of the Highlands," Roddie said. "Solar-power and locally sourced hydro- provide hot showers and electricity."

Kiersten Rich, owner of travel blog and Instagram account The Blonde Abroad, told Business Insider: "Situated in the protected Bazaruto National Park, the Bazaruto Archipelago is one of the best places I've ever been scuba diving, and is one of the more memorable and naturally beautiful places I've traveled."

"Never have I encountered wildlife so unafraid and curious of humans," Rich said. "The Galápagos National Park has taken incredible measures to protect all forms of nature and, in doing so, we can observe birds, reptiles and marine life more than anywhere else I've been in the world."

"Instead of joining resort-goers at Bora Bora, you need to explore the vanilla plantations of Taha'a Island, the tropical 'blue lagoon' of Rangiroa, and the lava tubes and secret waterfalls of Tahiti," Rich said.

"Namibia has one of the lowest population densities in the world which means long drives with nothing but nature," Rich told Business Insider.

"From the big-little-city of Cape Town to the delicious food and wine of the Stellenbosch Winelands [and] the game reserves helping to conserve and protect the Big Five [safari animals], South Africa is a magical place that everyone should experience," Rich said.

Airbnb's General Manager for Northern Europe James McClure said of Moscow: "I love the mix of history, art and architecture here — everything from 17th century townhouses to big Soviet blocks — combined with the energy of a massive and dynamic city. Next time I visit, I'm keen to try Airbnb's Local Georgian Food Experience which explores the tasty Georgian food you can discover in Moscow's food markets."

"When I lived in Singapore, I used to travel to Ho Chi Minh City every month," McClure said. "It's a city that rewards repeat visits once you get to know the local people there. The variety amongst the different districts is really stark, plus there's narrow lanes teeming with street vendors, river life, and fantastic food and nightlife."

"Whether you're going for an early morning surf at Bronte beach, or drinking [what is] arguably [the] world's best coffee, Sydney is overall a stunning city with access to sporting heritage and national parks very close by," McClure said. "I couldn't recommend the lifestyle highly enough."

McClure said Lake Toba is "the biggest lake in Southeast Asia, with an island in the middle which is bigger than Singapore."

"You can laze around on truck inner tubes in the lake, cycle around the island and stay in traditional homestays. It doesn't get much better than that."

"Surprisingly, I've never been," McClure said, adding: "I know it's fairly cliche but I really want to experience Rio Carnival one day."

Melissa Hie, the food and travel blogger who runs Girl Eat World, said: "The scuba dive sites here are pristine, colorful, and abundant with sea life. We saw everything from big fish like sharks and manta rays, to the small stuff like seahorses and nudi branches."

"The city of Kumamoto was hit with an unfortunate series of strong earthquakes in 2016 that left the city without water and damaged the precious Kumamoto Castle," Hie said. "I visited the place a few months after but it didn't stop us from taking a rental car and exploring around the beautiful mountain surrounding this region."
