If you're seeking adventure, breathtaking landscapes, and unforgettable experiences, the U.S. national parks have it all. What the U.S. lacks in architecture, art and history, it more than makes up for in its natural spaces. Each park offers unique features, from geysers and canyons to lush forests and coastal cliffs. 

This guide will take you through the top 10 national parks based on annual visitors, helping you decide which parks to add to your travel bucket list. We’ll also go over safety tips for spending time in the great outdoors. Lastly, we’ll discuss why you should buy a virtual SIM card for your trip to the U.S. and its national parks. 

What is a “National Park?”

A "National Park" is a protected area established and managed by the U.S. government to preserve its natural environment, wildlife, and cultural heritage for the enjoyment, education, and inspiration of present and future generations. Here are some key characteristics of national parks:

  1. Government Designation: National parks are officially designated by the U.S. government through legislation or executive action.
  2. Conservation Focus: The primary goal is to preserve natural and cultural resources, including landscapes, flora and fauna, and historical sites.
  3. Public Access: National parks are generally open to the public, providing opportunities for recreation such as hiking, camping, wildlife viewing, and educational activities.
  4. Regulated Use: Activities within national parks are regulated to minimize human impact and ensure the protection of natural and cultural resources. This often includes restrictions on development, resource extraction, and certain recreational activities.
  5. Research and Education: National parks often serve as sites for scientific research and environmental education, helping to increase public awareness and understanding of natural and cultural heritage.

In the United States, the National Park Service (NPS), a federal agency within the Department of the Interior, manages national parks and other protected areas, ensuring their preservation and accessibility for future generations.

Yellowstone National Park

Location: Wyoming, Montana, Idaho

Annual Visitors: Approximately 4 million

Highlights: Yellowstone National Park is likely one of the most well-known national parks in the world. It boasts 2.2 million acres of land and contains about half of the world’s active geysers. The most notable is Old Faithful, which spouts off at regular intervals to the delight of visitors. In addition to the geothermal activity, wildlife is abundant (bison, elk, grizzly bears, wolves), and the “Grand Canyon of the Yellowstone” is a marvel. 

Best Time to Visit: For fewer crowds and milder weather, consider visiting from April to May or September to October.

Grand Canyon National Park

Location: Arizona

Annual Visitors: Approximately 5.9 million

Highlights: As the name suggests, the primary attraction of this park is the Grand Canyon. It encompasses 278 miles of the Colorado River and adjacent lands. It is one of the grandest examples of erosion anywhere in the world. Notable viewpoints include Mather Point and Yavapai Observation Station. There are many opportunities to hike and every year, people make their way through the canyon on the Colorado River. 

Best Time to Visit: For pleasant temperatures and fewer tourists, consider visiting from March to May or September to November.

Yosemite National Park

Best Time to Visit: May to September offers the best weather to accessing roads and trails. But, this is also a popular season; reservations may be required to access the park.
