It's challenging to decide which natural wonders to visit first because there are so many to pick from. To assist, we have developed a list of the world's top national parks based on expert views and characteristics such as accessibility, the number of species, camping options, and impressive natural landmarks.

Yellowstone

Yellowstone National Park is a national gem because of the myriad attractions that may be found throughout its over 2 million acres. Many people return year after year to see see the wonders of Old Faithful and Mammoth Hot Springs, as well as less-traveled areas like Hayden Valley (a great place to see wildlife) and Yellowstone Lake (a great place to go canoeing or kayaking).

Yosemite

Yosemite is home to a wide variety of breathtaking natural wonders. Yosemite's famous Valley View and Tunnel View overlook, as well as notable features like El Capitan and Half Dome, are just a handful of the park's most popular attractions. Check out the enormous sequoia groves while you're in the area. There are also more than 750 miles of trails to explore in this California park.

Glacier National Park

Montana's crown treasure is Glacier National Park. One of the world's largest national parks, Glacier National Park covers an area of more than 1 million acres and features breathtaking alpine beauty. To get the most out of the park, plan to spend many days there.

Grand Canyon

You can't go wrong with this national park in terms of scenery. The Grand Canyon's varied colors, tremendous depth, and spectacular rock formations never fail to amaze tourists. A helicopter ride over the canyon, a rafting trip down the Colorado River, or a walk through the canyon on your own will all leave you in awe of the Grand Canyon's majestic beauty. 

Serengeti National Park

It's no secret that the Serengeti National Park in Tanzania is where The Great Migration takes place. Two million wildebeests and thousands and thousands of gazelles and zebras cross the park each year searching for breeding locations and food. If you can't guess when this historic event will take place, a regular tour is your best option. The Serengeti's spectacular terrain and wildlife, like leopards, elephants, lions, buffaloes, and rhinoceroses, are all within your grasp.

Jasper National Park

Enjoy a variety of outdoor activities, including biking, hiking, and boating, as well as ice climbing and cross-country skiing, during your visit to this national park. Spring and fall are ideal times to visit the park since they offer the best opportunity for birdwatching and rushing waterfalls, respectively. There's always a good chance you'll get a chance to look up at the stars in Jasper's second-largest dark sky preserve.

Torres del Paine National Park

You may see pumas, penguins, and whales in this area, but the terrain is the main attraction here. It is home to the Grey Glacier and the world-famous Cuernos del Paine, two of the park's most beautiful natural features. It is not uncommon to need a guide to do the longer O Circuit and W Trek hikes, which both take several days to complete.
