Yellowstone National Park is known for a lot of things, but perhaps not everyone knows that when it comes to our national parks, this beauty was the pioneer of its time. The park’s scenic geysers, vast forests, and stunning mountain peaks inspired its visitors to advocate for the conservation of the area’s natural landscape. In 1872, Congress named Yellowstone the first national park and established some of the procedures that would become the foundation for the preservation and care of over 400 public parks nationwide. What began as a relatively small movement in the wilds of Yellowstone spread across the nation, and throughout the world—today there are more than 1,200 national parks in more 100 countries.

As the U.S. National Park Service celebrates 100 years this fall, we, along with our friends at Audley Travel, have put together a list of our favorite international parks inspired by some of the great U.S. national parks. In other words, if you’ve got a soft spot for the high peaks and snow-capped mountains of Rocky Mountain National Park, just wait till you get a look at the Atlas Mountains in Morocco’s Mount Toubkal National Park.
