As much as we love lounging on a faraway beach or revisiting our favorite city for the tenth time, sometimes our passports need some adventure travel—we’re talking about those once-in-a-lifetime trips that push us way outside our comfort zones. Adventure travel is a great way to see more of the world, while also testing your physical limits, and coming home with a lifetime’s worth of stories to tell at parties.

Below, we’ve rounded up some of the most incredible outdoor adventures for intrepid travelers, ranging from climbing Machu Picchu to skydiving in Dubai. Even if you don’t consider yourself a daredevil, you’ll still find activities that feel exciting (hello, camping under the northern lights) without too much physical—or emotional—exertion required. So fasten your seatbelts, grab your best pair of hiking boots, and get ready for the adventure of a lifetime.

Boat under the Iguazú Falls

South America’s Iguazú Falls, located on the border of Brazil and Argentina, make all other waterfalls look like mere trickles in comparison. The system of more than 200 cascades (reaching heights of around 270 feet) can be viewed from surrounding walkways and catwalks, but we’re fans of the more adventurous vantage-point—hopping on an Iguazú Jungle inflatable raft and sailing directly under the exhilarating, high-pressure falls.

Climb to Machu Picchu

No adventurer’s must-visit list is complete without Machu Picchu, the famous Incan citadel located in the Andes. While the site can be accessed via train and bus, more active travelers can take the five-day trek along the entire 26-mile-long Inca Trail. Or, thanks to local tour operator Sam Travel Peru, you can get dropped at kilometer marker 104 and do the whole experience in 24 hours.

Sand surf in the Sahara

The dunes of the Sahara are colossal, untouched, and tailor-made for extreme sports. The desert’s rows of barchans (meaning “crescent-shaped dunes” in Turkic) have ideal shapes for sand surfing (descending the slopes on a surfboard) and sandboarding (descending the slopes on a snowboard)—and those views don’t hurt, either. Stay at Erg Chigaga Luxury Camp in Morocco, which offers sandboarding in addition to other desert activities like camel rides and quad biking.

Heli-hike in British Columbia

With CMH Heli + Skiing, you can helicopter to the steepest and deepest powder in Canada for backcountry skiing. However, come summer, the company’s guides take guests on multi-day hiking trips to terrain otherwise inaccessible, along ridgelines, through alpine meadows, and to stunning viewpoints. While these high-altitude adventures are not for the faint at heart, the accommodations are quite comfortable, with log-hewn lodges complete with full-service restaurants, spa treatments, and a rooftop hot tub to relax in before another day on the trail.

Hot air balloon over Cappadocia

A hot air balloon ride over central Turkey’s Cappadocia region provides 360-degree views of the famous limestone spires and “fairy chimneys”—something you can’t get at the ground level. We recommend booking with Kapadokya Balloons, the first company that introduced hot air balloon tourism in Cappadocia. Services include transfers to and from your hotel, snacks, full insurance, and a champagne party after the flight.
