We’ve cracked the top five on our list of the largest national parks in America. Death Valley National Park is the 5th largest national park in America at 3,408,395.63 acres (13,793.3 km2) and the largest national park outside of Alaska.

Despite the morbid name Death Valley has an abundance of life and incredible sights. So long as you don’t visit during the summer when temperatures can soar into the 130s you’re bound to have a great time here.

4. Katmai National Park
Katmai National Park is the 4th largest national park in the US at 3,674,529.33 acres (14,870.3 km2).
We’ve all seen the famous bearcam of the grizzlies hunting salmon at Brooks Falls, and we all want to see that in person (safely behind the plexiglass viewing area) along with the countless other hard-to-fathom landscapes that exist within this amazing park.
The fact of the matter is that it just ain’t easy (or cheap) to do so. Getting to Katmai typically requires multiple flights and thousands of dollars which puts it squarely out of reach for most Americans.
Accessing Katmai National Park is expensive. There are no roads that lead into the park which means getting to Katmai requires a flight (and we’re not talking a standard commercial flight).

Alaska’s flagship national park named for its tallest mountain which happens to be the highest peak in North America, Denali is on every park-goers bucket list. The breadth of this mountain is hard to appreciate and so is the size of the park itself at 6.1 million acres.

1. Wrangell St. Elias National Park
- Size: 13,175,799 acres (53,320.57 km2)
- Location: Alaska
- My Favorite Resources: Guide | Map | Guidebook
At over 20,000 square miles, the largest national park in the United States is Wrangell St. Elias National Park.
As one of the more accessible Alaska parks, Wrangell makes it into our top 20 US national parks for that reason alone. Wrangell is an Alaska national park full of superlatives and a world unto itself.
It is a park of otherworldly and seemingly impossible landscapes. The difference at Wrangell vs some of Alaska’s national parks is that you can take a car and drive to some of them.
Wrangell St. Elias National Park is the largest in the US at over 13 million acres. The park features 9 of the 16 tallest mountain peaks in the country.
The massive scale of Wrangell is truly hard to fathom. So, bear with me for some comparisons.
If Wrangell St. Elias National Park was a country it would be the 121st largest ahead of nations like Denmark, the Netherlands, and Switzerland.
Wrangell St. Elias is larger than the four smallest US States combined including Rhode Island, Delaware, Connecticut, & Hawaii.
