Even if you can't name them all, you've probably heard of the 7 Wonders of the World. However, the lesser-known truth is that there are several different categories of world wonders. The Ancient Wonders of the World, for example, include man-made architectural marvels that date back millennia, such as the Great Pyramid of Giza, the Temple of Artemis at Ephesus and the Colossus of Rhodes. Very few of these still exist today, but the ones that still stand strong are popular cruise destinations.
What are the 7 Natural Wonders of the World.? As the name implies, this group includes nature's most majestic feats — such as the Grand Canyon, Mount Everest, the Great Barrier Reef and the Northern Lights. The list has been altered and edited by many different people over the years, and in 2008, an organization was created by conservation and exploration experts to protect and promote these awe-inspiring wonders.
How many of the Seven Wonders of the World still exist today? They all do — and while they're not all easy to reach, any world traveler such as yourself can visit or catch a glimpse. Here's what they are, how to see them and why they're worth adding to your adventure bucket list.
Australia's Great Barrier Reef is the world's largest coral reef system — a distinction that earned it a spot on the Seven Natural Wonders list. Recognized as a UNESCO World Heritage site, this sprawling expanse encompasses 133,000 miles, comprises more than 2,900 distinct reefs and 900 islands, and supports one of the world's most diverse ecosystems. It's so big that it can even be seen from outer space.
While perhaps not as easy to get to as the Grand Canyon, it’s still accessible to visit the Great Barrier Reef via diving, snorkeling or kayaking tours. Most visitors start their adventures on dive boats departing from Port Douglas, Townsville, Cape Tribulation, Cairns, or even during a relaxing cruise to Airlie Beach, Queensland. If scuba diving isn't quite for you, you can join a snorkel or kayak tour — several set out from Master Magnetic Island, a small isle just off the coast of Townsville. But the best way to experience the reef is indeed underwater. Some of its residents include manta rays, blanket octopi, giant clams, and even humpback whales.
This is the only one of the 7 Natural Wonders of the World not tied to one geographical location. The Northern Lights offer plenty of options to be seen worldwide. One of the best ways to view them is to explore Alaska by cruise, and the trick to seeing them is to time your visit right. This naturally occurring phenomenon, also known as the aurora borealis, appears as dancing bands or curtains of colored light in the sky. The aurora is caused by electrically charged particles that blow into our atmosphere from solar storms, so it's difficult to pinpoint exactly when or where it will appear. But research has shown your chance of catching the northern lights is best at certain times of the year in remote, northern places where skies are dark and light pollution is minimal.
Denali National Park in Alaska is a prime spot, especially in the fall, winter and early spring when the nights are longest. Tromso, Norway and Swedish Lapland are also good choices, in the heart of the aurora zone. You can even catch the Northern Lights from parts of Michigan's Upper Peninsula, though sightings here occur far less frequently than destinations closer to the Arctic Circle.
One of the most accessible among the 7 Natural Wonders of the World is the Harbor of Rio de Janeiro in Brazil, also known as Guanabara Bay. Formed by erosion from the Atlantic Ocean, it's surrounded by towering granite mountains and rock formations and dotted with beautiful islands. It's also the largest bay in the world by volume of water. So, why is the harbor of Rio de Janeiro a wonder? Its dramatic formation, striking scenery and cultural significance offer a clear answer..
While visiting the Christ the Redeemer statue is an epic experience with breathtaking views, you can also head to the skies on a helicopter tour — or via hang glider, if you're craving an adrenaline rush. You can easily find tours locally in Rio. Experienced mountaineers prefer to view it from the top of Sugarloaf Mountain, which is actually in the harbor and yields captivating views of the bay, the mountains and the city of Rio de Janeiro. You might even catch a glimpse of Corcovado Peak. But two of the easiest ways to experience this natural wonder include enjoying one of the fine, white sand beaches that hug it or setting out on a scenic cruise to Rio de Janeiro, for a close-up, once-in-a-lifetime experience around nearby islands and rock formations.
One of the most famous natural wonders of the world is Mount Everest, located in the Himalayan mountains that stretch between China, Tibet and Nepal. Compared with other mountains, Everest doesn't have the greatest vertical rise, but it's designated as having the highest point in the world. It is commonly referred to simply as Mt. Everest. Its tallest peak rises to an elevation of over 29,000 feet. Tibetans have another name for this towering marvel: Chomolungma, which means "Goddess Mother of Mountains." Because of its staggering height and the dangerous conditions at such high altitudes, summiting the mountain is extremely risky and something only the most experienced climbers should attempt. It's also a costly undertaking that requires hard-to-get permits. A much safer, easier and cost-effective way to admire Mount Everest's majesty is from the mountain's base camp and the surrounding national park. You can also opt for a guided flight around the mountain from Kathmandu, which offers captivating views.
Some even compare this journey to visiting other widely revered sites in the world, such as Chichen Itza or the Great Wall, both included on various “Seven Wonders” lists (though those are manmade wonders of the world).
How many wonders of the world are there to see in a lifetime? While there are many world wonders these, the 7 Natural Wonders of the World represent some of nature's most impressive creations. Whether you feel most drawn to the Grand Canyon's surreal rock formations, the Great Barrier Reef's vibrant marine life, Mount Everest's soaring, snow-covered silhouette, or all seven wonders in equal measure, you should definitely try to visit as many as you can.
Regardless, nothing compares to the sense of awe accompanying seeing the northern lights firsthand or hearing the booming roar of Victoria Falls with your own ears. Take the time to enjoy our world, add these one-of-a-kind wonders to your travel vacation plans and explore cruises that help you experience them in the best possible way.
