The National Park System comprises 63 national parks and over 350 national park sites that stretch over more than 84 million acres. Dotting across all states and U.S. territories, the sites range from large, well-known parks like the Grand Canyon and Yellowstone to historically significant places, like the birthplace of Martin Luther King, Jr.
Whether exploring history or sight-seeing, our national parks provide a wonderland of recreation and education.
When visitors saunter along a national park pathway, they inevitably bring along their smartphones to take pictures and record their adventures. How would anyone believe you were there if you didn’t post it on Instagram? Of course, it’s not just about the “pics or it didn’t happen.” You’d need good service if there is an emergency, to make further plans, or to check in with your homebase.
You may also want to spend a few days at a park and work remotely or get other digital comforts you’re used to. For that, you’d need reliable and strong mobile service. So before you set off on your journey through a national park, be sure it has the necessary mobile service. (Want to travel to a city and be assured of good broadband?

To find the 10 national parks with the best mobile service and the 10 with the worst, 24/7 Tempo reviewed Speedtest’s feature, “Choose Your National Park Adventure: The Best Places to Work Remotely or Digitally Disconnect.” Speedtest analyzed mobile services at U.S. national parks for median download and upload speeds as well as 4G and 5G availability.
Missouri’s Gateway Arch provides the best mobile service among national parks. It offers 5G availability and near 100% 4G availability. Median download speed is 84.6 mbps (megabytes per second), and median upload is 31.1 mbps. This is likely not surprising considering the park is in a major metro area, St. Louis. Many parks near urban areas have better mobile services.
The park with the poorest service is Sequoia Park in California, where 4G availability is a scant 4%, with no 5G availability. Both median download and upload speed crawl at 1.4 mbps. (Based on size, here are the largest and smallest national parks.)
Whatever the mobile service at any national park, simply being able to enjoy the wonders around us is worth the trip and perhaps hassle of poor service.
