What is a national park unit?

National parks in the national park system

These are our 63 well-known National Parks, including Yellowstone and Yosemite.

National park units in the national park system

While the 63 parks above are the most famous park units in the system, the other 370 national park units are less well known and are less clearly defined.

  • 25 Battlefields & Military Parks
  • 76 specific Historic Sites, including some battlefields and many military forts
  • 64 general Historical Parks, including some more battlefields
  • 31 Memorials for people, places and both positive & tragic events
  • 11 Gardens and undesignated areas, including some more memorials
  • 87 Monuments, including natural areas, some more battlefields and more military forts
  • 76 Preserves, Recreation Areas, Rivers, Shores and Trails, both protecting wildlife and supporting fishing & hunting

President Lincoln first protected Yosemite Valley. Then Grant created the first national park, Yellowstone. Then Teddy Roosevelt created five more, plus various bird reserves, national forests, and monuments, and he signed the Antiquities Act into law. Then Wilson signed the Organic Act which created the National Park Service. Stephen Mather was instrumental in making the parks into what we see today. And since then, there has been a wide variety of additional legislation, creating, ending, renaming, and reorganizing various types of parks for different purposes, including historic sites, rivers, trails and wilderness.

Turns out, a national park unit is quite arbitrary. Either the President or Congress can authorize a national park unit under different legislation, and they can and do change their status too. Leaders regularly reinvent what a park unit is, what it’s for and why it’s important (or not). Presidents on average increase the total by a couple units per year. But it varies; last week the President shrank two national monuments in Utah. All of which makes my trip planning a moving target.

Officially, there are now 433 national park units of the National Park Service (NPS) managed under rules standardized in 1970. I’ve been to 400.

Extra sites not considered park units that are within the national park system

I joined the non-profit National Park Travelers Club (NPTC) to track my visits on their parkstamps.org checklists, and their like-minded community of travelers has been wonderfully helpful. The NPTC got me interested in NPS-related affiliate sites, heritage areas and trails too, and I’ve been to over 100 of these.

  • 32 Affiliates including yet more battlefields, historic sites and memorials
  • 62 Heritage Areas covering broad areas
  • 27 Trails in addition to 6 Scenic Trails that are park units above
  • 50 Wild & Scenic Rivers are also part of the park system
  • 3 Commemorative sites
  • 5 Authorized sites not yet open (typically waiting on private land transfers)
  • 1 co-managed area next to the Grand Canyon

Same type of national park units outside the national park system

Confusingly, there are 1/2 a dozen other federal agencies that also manage exactly the same types of national park units as the NPS, sometimes jointly and sometimes on their own, often under different or even conflicting rules. This leads to confusion on many websites as to exactly how many national monuments and other types of park units there are in the US. And I have to decide whether to include these units or not.

When I began my quest to see our parks, I assumed that NPS management must mean that the site is worth visiting, but one of the first NPS sites I tried to visit is permanently closed to the public with nothing to see or do. Meanwhile, there are non-NPS national monuments over 1 million acres, extraordinarily beautiful, unique in the world, and as important as they are unforgettable.

If a national historic site, monument or recreation area is important enough to be so designated by the President and/or Congress, then it belongs on my EV road trip itinerary, regardless of which government agency manages it. If a President designates a new national monument in the middle of a large national forest, management likely goes to the US Forest Service (USFS), even though it’s not any less important than other national monuments.

So, don’t be surprised to read about a USFS national recreation area or a national monument managed by the Bureau of Land Management. I’ve already posted about several, and I plan to visit more of the following units outside the NPS.

  • 1 Historic Site
  • 51 Monuments
  • 23 Recreation Areas

Where to draw the line on what to see

But I’ve also decided I can’t visit everywhere I’d like to go.

The NPS manages 50 wild & scenic rivers, but other agencies manage more than 175 other wild & scenic rivers, which are equally verdant. That’s too many for me, so I only plan to visit most of our national recreational, scenic and wild river systems that are over 100 miles long. I’ve already seen our shortest wild & scenic river.

There are over 1250 national recreational trails managed by other agencies. While I’ve hiked many, I’m going to stick to the 33 NPS related trails, but feel free to hike the rest.

There are also over 800 national wilderness areas in the US, plus over 500 national wildlife refuges. Many wildlife refuges do not have any roads, since they’re set aside for forests, wetlands and wildlife, not for people. And that is a problem for my electric car and for me.

Our country is full of so many fascinating travel destinations, that there’s simply not enough time to see them all. I’m an old man, and I don’t want to spend the rest of my life futilely checking off 2,600+ landmarks, 700+ lighthouses, and ~10,000 state parks. No, I need to draw the line for my own sanity.

I happily drive through national forests and cross scenic rivers every trip, but I usually do so without mention. I’m leaving wilderness areas and wildlife refuges to the plants and animals. I wish I could visit every forest, hike every trail, paddle every wild river, and explore every wilderness and wildlife refuge in the country, because they’re critically important for saving species, especially as so many lands are being damaged irreversibly by the climate crisis. But I can’t, so I will only mention a few of them occasionally in passing. However, these are our public lands, and I hope you care about and help protect them too. Thanks.

All Pacific Northwest Sites

Alaska awaits, but in the meantime, I have visited all 4 National Parks and 16 park units in the Pacific Northwest region, plus 2 heritage areas, 1 affiliate, trails and biospheres. Part of the Manhattan Project NHP is in Washington too.

The four national parks all contain snow capped volcanoes. There are fossil, cave and geologic sites, 3 lake recreation areas, and many fascinating historic sites to enjoy. The region is beautiful, with rugged coastline, forests, mountains and wildlife.

Redwood National and State Parks

After Yosemite’s magnificent waterfalls, stunning vistas and valleys, Redwood is quieter, with more solitude and an intimate closeness with the trees: less spectacle and more spiritual. This World Heritage Site is a marvelous place to get lost alone among giants, to reminisce as if traversing the great forests of Middle Earth. One of the young hikers strode in full Frodo costume, looking for Ents. As some of the trees living here predate all but the earliest human history, you can’t blame him for getting into the spirit. When Frodo first entered Lothlórien to seek Galadriel’s help, he spent his first night in a treehouse in a giant Mallorn tree. “He felt a delight in the wood and the touch of it, neither as forester nor as carpenter; it was the delight of the living tree itself.”

My favorite park for tall trees, the redwood forest is real and huge, so plan on hiking. The photo above is near Trillium Falls on a highly recommended 3 miles hike in the National Park from Elk Meadow near the south end of the park. I also walked from the Prairie Creek visitor center up to Big Tree—a Giant Coastal Redwood—in the Prairie Creek State Park on the Knapp trail returning on the Cathedral trail on the other side of the scenic drive. There are several ways to do the 3 mile loop, as well as plenty of shorter or longer hikes from many trailheads, flat or up onto ridges or down to the coast. There are also tide pools, fresh water lagoons, beaches, mountains, camping, elk (I saw 12) and more. Best of all, it was 30 degrees cooler than inland in July. The coastal redwood forest is lush and beautiful, safe for now.

“Many of these trees were my friends.
Creatures I had known from nut or acorn.
They had voices of their own.”

John Day Fossil Beds National Monument

John Day was merely an unfortunate trader who got robbed along the river here, but the event was noteworthy enough that this Columbia River tributary was named after him, then the whole region in Oregon. I first explored the area in 2017 when finding a campsite to observe a full solar eclipse, but I skipped the fossils. I really should have visited the museum earlier.

The John Day Wild & Scenic River flows through a huge volcanic landscape that contains the best Cenozoic fossils discovered in the country. Layers of forests and ash preserved some of the most important fossils used to understand evolution. The Cenozoic is the age of mammals, including the John Day Tiger above and the big entelodont (pig/hippo) behind it on the left. There is a camel skull, a gomphothere (elephant) jaw, mastodon teeth, horns of a giraffe-deer, bones of a short-faced bear previously thought to live only in Asia, rhinos, and some kind of giant dog-bear called a nimravid. There are also fossils of the Dawn Redwood, which still lives in China. The fossils I’ve seen at Fossil Butte, Florissant and Agate are all from periods covered here. If you have time, it’s possible to hike in the three separate remote park units, but the exhibits above are in the Condon Visitor Center in the Sheep Rock unit near the scenic Picture Gorge.
