It may be the closest (fingers crossed) you’ll ever get to encountering alien-like life forms. The northern lights are a natural spectacle of shiny green, blue and purple waves of light dancing in the night sky, like a kind of extraterrestrial water feature excited to just exist. Located in a region known as the Auroral Oval, the aurora borealis’ dazzling display forms as a result of the sun ejecting clouds of gas which, two to three days later, meet the Earth’s magnetic field and generate this spectacular show. The phenomenon is most common between September and March high in the Northern Hemisphere (Iceland is a particularly great location for viewing). Many cultures around the world have tried to explain the origin of the lights. Cree First Nations people, for example, once believed they were the spirits of the dead trying to communicate with their earthbound loved ones.

Staying in the Northern Hemisphere, this destination is jaw-dropping. A majestic piece of rock that reveals itself one out of every three days (due to cloud cover). Denali — “the tall one” in the Koyukon language — is not only the highest mountain in North America (at 20,310 feet) but also the third highest of the “Seven Summits” (the tallest peaks on each continent). Visiting requires an 18-day round trip that includes a hair-raising flight in a small plane that lands on a snow-covered strip, where you’ll be met by some of the lowest temperatures on Earth. Attempting to reach the top is recommended only for the most experienced climbers. Thankfully, the rest of us can still enjoy its imposing gorgeousness from the forests of its namesake national park or, more likely, from the comfort of our sofa.

Ukraine offers many overnight train services connecting its biggest cities. To paint a picture: a couchette complete with two foldable bunk beds, pillows and duvets, as well as a tiny folding table set against laminated wooden walls, a small window and two dainty curtains. In the hallway you’ll find more dated fabric curtains and a carpet that hasn’t been washed for decades. Eleven hours after jumping on the train in Ukraine’s capital, Kiev, you’ll arrive in Zaporizhzhia, the country’s fifth largest city and an industrial center that boasts a number of Soviet-era artifacts. While certainly a worthwhile journey, be aware of current travel advisories in place both by the Ukrainian government and by foreign governments as Ukraine prepares to declare a state of emergency due to tensions with Russia.

This colorful, enigmatic and vibrant port city is a perfect secluded escape in the corner of the Peruvian Amazon. Buried in South America’s lushest jungle, Iquitos can only be reached by boat or plane. Dubbed the “Venice of the Amazon, ” it’s a gateway to South America’s past, where well-preserved Spanish colonial architecture combines with the rich sounds of tuk-tuks and jungle creatures nearby. Hungry? This former rubber-producing settlement is also home to bustling food markets featuring the super sweet lucuma, believed to have anti-aging properties, and the peach-like aguaje. If you’re craving more than fruit, head to Belén, a floating settlement in the south of Iquitos. The sprawling market there offers everything from fresh fish caught by local villagers to insect larvae and even bottled ayahuasca, a psychoactive brew popular in this part of the world. Take note: It should only be consumed by those in the know.

There’s something hypnotic about prehistoric rainforests. The spectrum of greens, the smell of mist, the fluorescent flora hugging the damp bark of towering trees. Life grows upon life and worlds within worlds evolve as they’ve done for millennia. Tasmania, the island off Australia’s east coast, has so many rainforests you’ll be spoiled for choice, such as Tarkine, in the island’s northwestern corner. This area boasts unbelievably diverse terrain, from mountain ranges to raging rivers, sandy beaches, grassy woodlands and the cutest, craziest animals you’ll ever see (yes, we mean the Tasmanian devil). No wonder Indigenous communities have had such a deep connection to this corner of the world for more than 40,000 years.

Speaking of ancient times, if boulders “rock” your boat, then Argentina’s Quebrada de Humahuaca is the place for you. A small town nestled in the foothills of the Andes, its name comes from its rich Indigenous heritage. It’s a favored stop for people trekking this section of the Inca Trail, offering a window into how early farming communities lived 10,000 years ago. The miles of gigantic red, orange and brown rocks that dot the region serve as an enormous archaeological museum. Hone your ears to the howl of the wind that has been shaping the landscape for millennia and, better still, listen for the traditional tunes that fill the air and the hearts of the people in this corner of our planet. But what’s more – the food here is as good as the view. Heard of quinoa? This is its homeland. Enjoy it as a side with locro, a hearty stew made from potatoes, carrots and beef, and wash it down with chicha, a fermented, corn-based alcoholic beverage. Worried about the altitude? At nearly 10,000 feet above sea level, it’s certainly a consideration, but don’t despair — that’s what coca leaves are for.

Looking to really get off the beaten track, and stay safe? This tiny kingdom’s relatively untouched landscape and sustainable culture could be exactly what the doctor ordered. With 90% of its adult population fully vaccinated against COVID-19, Bhutan is among the safest places to be. For those who make the trip, head to the astonishing Tiger’s Nest monastery to appreciate spectacular views and architectural genius at an altitude of over 10,000 feet. But if you’re looking for complete solitude, Jigme Dorji National Park is the place to go. Its verdant, mountain-ringed valleys, dotted with colorful huts and temples, are ideal for trekkers or anyone searching for a cure for screen-weary eyes. The catch? Traveling around this tiny nation is only allowed with a local tour guide, which changes the meaning of solitude. Still, don’t let that put you off, as the authorities are looking to protect the country’s pristine environment from excessive tourism.

An Indian Ocean island and UNESCO World Heritage Site, Socotra is, simply put, out of this world. Located some 220 miles south of mainland Yemen, this place is so special that many animals and plants are endemic to the island, such as the dragon blood tree and the Socotran chameleon. But there’s one more thing that makes Socotra feel almost alien: its mind-blowing white dunes, formed by years of strong winds blasting the island’s rocks. Be warned: Ascending these sandbanks is a cardio workout, but the reward when you reach the top is nothing short of spectacular. Considered one of the most remote places on earth (although it now has an airport), Socotra’s rich history attracts intrepid travelers looking to leave the beaten path behind.

The Maletsunyane Falls in Lesotho plunge into a gorge so deep that the sun can’t reach its lowest points. Icicles can be found throughout the winter and spring. When you walk by this waterfall, which features one of the steepest drops in the Southern Hemisphere (630 feet, to be precise), your hearing feels superhuman. Close your eyes and listen carefully to the deafening sound of the furious water crashing into rock, much like the screams of people past, at least according to one terrifying legend. Scary stories aside, it hasn’t put off a handful of wild adventurers who every year travel to the area to rappel from the edge of the falls. If rock climbing and skydiving are not your cup of tea, you can always enjoy some of the most beautiful parks in this corner of Africa. Fun fact: Lesotho is the only nation in the world that is entirely 3,280 feet above sea level, with 80% of its territory reaching heights of 5,905 feet.

If you spend enough time observing the Pacific Ocean’s waves, impatient and determined — as if purposefully trying to get somewhere — you can almost hear them speak. There are many places in the world to view the power of our largest mass of water, but few offer as winning a seat as San Agustinillo, a tiny fishing village hidden between some of Mexico’s most popular beaches. This strip of sand, home to a smattering of cabins and shacks, is the perfect spot for those easing their way back into the rat race of modern life. What more could one ask for than quiet evenings, huitlacoche fungus tacos and mezcal cocktails? Best of all, a short drive away, on Escobilla beach, visitors can visit a turtle sanctuary and rescue center — and help release hundreds of baby turtles back into the sea.
