National Park Road Trips

The Ultimate National Park Road Trip

One loop connects every national park in the contiguous United States — 47 of them, from the Florida Keys to the Olympic coast. Driven in the right order, it's a single continuous route, not 47 separate trips.

Why this loop

Why these parks, in this order

Visiting all 47 sounds like a lifetime project. It isn't — if you drive them in the right order.

Data scientist Randal Olson mapped the shortest possible route that connects every one, and that's the loop this guide follows. It's a loop, not a line: there's no official start or finish, so you can join it at whichever park is closest to home and drive in either direction back to where you began.

The order is what makes it work. Each leg below is a tight group of parks you can drive between in a day or two, and the legs chain together so you're always moving forward around the country instead of doubling back across it.

Before you commit

What the full loop actually takes

Driven end to end at a fast pace, the loop is about two months of near-constant driving. That's the honest number, and it's why almost nobody does the whole circuit at once.

The loop suits some travelers better than others. If you're retired, working remotely, traveling by RV or van, or stringing together a long sabbatical, the full route is realistic. If you have two weeks, pick one leg and do it properly rather than rushing the whole country.

  • About two months end to end at a fast pace — plan one or two legs per trip if your time is shorter.
  • Four parks need a boat or seaplane: Dry Tortugas, Biscayne, Isle Royale, and Channel Islands. Book those crossings well ahead.
  • Isle Royale closes from November to mid-April — fit it into a summer leg.
  • The northern parks — Glacier, the North Cascades, Yellowstone's high country — are summer-only; their high roads don't open until the snow clears.
  • Big Bend and Death Valley are remote and hot. Go in spring or fall, and fill the tank before you arrive.

The route

The loop, leg by leg

The order below is the loop in driving sequence. Each park links to its full Atlas trip guide where one is built; the rest are on the way.

The Southwest

Three Arizona parks sit within a day's drive of each other, which makes the desert Southwest the easiest place to begin — and the Grand Canyon is the anchor most people plan the whole trip around.

  1. 1
  2. 2
    Petrified Forest AZ
  3. 3
    Saguaro AZ

West Texas & Southern New Mexico

Two of these share a mountain range across the Texas–New Mexico line. Big Bend is the long detour south to the Rio Grande — remote, and worth the fuel.

  1. 4
    Guadalupe Mountains TX
  2. 5
    Carlsbad Caverns NM
  3. 6
    Big Bend TX Remote far-West Texas — the nearest fuel and supplies can be an hour out.

The Mid-South

The route turns east across the South, picking up two cave-and-spring parks and the most-visited park in the country before the run down to Florida.

  1. 7
    Hot Springs AR
  2. 8
    Mammoth Cave KY
  3. 9
    Great Smoky Mountains TN

Florida

The Florida parks are a peninsula dead-end, so you do them as an out-and-back. Two of the three are mostly water.

  1. 10
    Everglades FL
  2. 11
    Dry Tortugas FL Ferry or seaplane only, from Key West — book well ahead.
  3. 12
    Biscayne FL Almost entirely water; a boat tour is the way in.

The Atlantic Seaboard

Back up the Eastern Seaboard the parks thin out and spread apart. Acadia, on the Maine coast, is the northeastern turn before the route heads west.

  1. 13
    Congaree SC
  2. 14
    Shenandoah VA
  3. 15
    Acadia ME

The Great Lakes & North Woods

Across the top of the Midwest, two of these are remote north-woods parks on the Canadian border. Isle Royale is an island in Lake Superior.

  1. 16
    Cuyahoga Valley OH
  2. 17
    Isle Royale MI Ferry or seaplane only, and closed November to mid-April.
  3. 18
    Voyageurs MN

The Northern Plains

The badlands and the Black Hills make a tight three-park run before the climb into the Rockies.

    Theodore Roosevelt ND
  2. 20
    Badlands SD
  3. 21
    Wind Cave SD

Colorado

Colorado packs four parks into one state — alpine peaks, the tallest dunes in North America, a sheer canyon, and ancient cliff dwellings, each a different landscape.

    Great Sand Dunes CO
  3. 24
    Black Canyon of the Gunnison CO

Utah's Mighty 5

Utah's five parks are close enough to drive in a week, which is exactly why we've built the day-by-day version as its own field-tested guide.

The Great Basin & Greater Yellowstone

Cross the Great Basin to the Tetons and Yellowstone — the busiest stretch of the whole loop, and the one to reserve earliest.

  1. 31
    Great Basin NV
  2. 32
  3. 33

The Northern Rockies & Cascades

The northern tier is summer-only country: Glacier's high road and the Cascade passes don't open until the snow clears, usually not before late June.

  1. 34
    Glacier MT The Going-to-the-Sun Road opens only in summer once plows clear the pass.
  2. 35
    North Cascades WA
  3. 36
  4. 37
    Olympic WA

The Pacific Coast & Volcanoes

Down the Pacific side the route trades alpine for volcano and old-growth — a caldera lake, the tallest trees on earth, and a still-active volcanic park.

  1. 38
    Crater Lake OR
  2. 39
    Redwood CA
  3. 40
    Lassen Volcanic CA

The Sierra Nevada

California's Sierra parks stack up the center of the state. Yosemite anchors them, with Kings Canyon and Sequoia just south and Pinnacles out toward the coast.

  1. 41
  2. 42
  3. 43
    Sequoia CA
  4. 44
    Pinnacles CA

Southern California

The last leg drops into Southern California and closes the loop back toward the Grand Canyon — desert again, where you started.

  1. 45
    Channel Islands CA Boat only, from Ventura or Oxnard.
  2. 46
    Joshua Tree CA
  3. 47
    Death Valley CA Summer heat is extreme — spring and fall are the windows.

Make it real

Pick your leg and start planning

You don't have to drive all 47 at once, and you shouldn't try. Pick the leg that fits the time you have — the Mighty 5 across Utah, the Colorado four, the Washington three — and plan that stretch properly.

Every park above links to its full Atlas trip guide as we build it out. For the legs that are ready, the field-tested guides give you the day-by-day: where to stay, which hikes to prioritize, when to book permits, and the contingency plan for when a road or a trailhead is full.

One pass, every park

One pass covers every national park on this route.

The America the Beautiful annual pass covers entry to every park on this loop. On a trip that strings together this many parks, it pays for itself long before you finish the first leg.
