No list of the world’s top national parks would be complete without the Yellowstone National Park, which is also considered the world’s oldest. Located in Wyoming and extending into Idaho and Montana, the park was established in 1872.
Now, it’s a premiere tourist destination that welcomes thousands of visitors to its doorstep each year. It’s primarily known for its extensive wildlife and wide range of ecosystems, including the subalpine forest, which is the most abundant in the area. It also features the Old Faithful Geyser, a geothermal ecosystem.
The park’s 3,468 square-mile land is home to hundreds of species of birds, reptiles, mammals, and fish, and countless unique plant species.
