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 Mount Fuji

Solitary Mount Fuji is probably Japan's most iconic natural wonder, rising 12,388 feet above villages and reflecting on lakes' surfaces. You can get views of the landmark from many places, like Lake Kawaguchi in Fujikawaguchiko and even the Park Hyatt Tokyo, but it's the views from the mountain that give you the most bragging rights. Visit from early July to mid-September (fingers crossed for 2022) to take advantage of the official climbing season, when the designated trails and paved roads are free from snow.

Swim through Mexico's cenotes

Mexico’s Yucatán Peninsula features a wealth of unique natural beauty, particularly when it comes to its cavernous cenotes. Floating in one of these natural sinkholes is an incredible experience, as is diving through the underground cave systems. When in Tulum, visit Dos Ojos (“Two Eyes”) to view one of the planet's most beautiful underwater sites (bonus points for water visibility), or Gran Cenote for rock formations that resemble Gothic architecture.

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.
