The U.S. National Park Service will mark its 105th birthday on Aug. 25 by offering free admission that day to all 423 of its sites. Aug. 25 is one of three “free entrance” days left on the 2021 calendar; the other two are Sept. 25 (National Public Lands Day) and Nov. 11 (Veteran’s Day).

The park service is planning several in-person and virtual activities to commemorate the occasion. It varies by location, but the offerings include activities such as free camping at Big South Fork National Recreation Area near the Kentucky-Tennessee border, and a guided hike through Hot Springs National Park in Arkansas. You can find a list of all the events and activities happening that day on the official NPS website.

Each year the park service offers these too-good-to-resist days for families to enjoy the great outdoors at some of the most spectacular natural wonders in America. So if you have the capacity to plan a last-minute trip into the great outdoors, get to it.

A few caveats to be aware of: The most popular of the country’s parks, like Yosemite National Park, may not be available on Aug. 25 or the remaining free-entrance days. Because of the high demand to enter such popular destinations and the desire to avoid overcrowding, reservations are now required by the park service for entry into the most popular parks. You can make reservations for the parks here.

Also, we want to point out the park service offers free admission year-round to several groups, including veterans, Gold Star Families and U.S. citizens and permanent residents with permanent disabilities.

Pent-up demand for travel has sent visits to national parks surging this year, with Yellowstone National Park and Grand Teton National Park among those breaking visitor number records, according to a June 11, 2021 story in the Billings Gazette.

A helpful tip to enhance your own user experience if you plan to visit on one of the fee-free days is to pass on visiting beautiful but busy spots like Olympic National Park and Acadia National Park in favor of lesser-known park service sites instead.

“While there’s no replacement for Yellowstone and Yosemite, there are lots of national monuments and other national park service units that can give you that big national park experience without the crowds,” says Jason Epperson of the RV Miles, website and podcast, whose family has visited over 50 national park service sites during five years of living full-time on the road.

Epperson points to Dinosaur National Monument on the Colorado/Utah border, which offers “epic hikes, large canyons and white water rafting” in addition to real-life dinosaur bones for viewing, as a good option for ditching the masses

If Aug. 25 is too close for you to plan an outdoor adventure, or if you’ll be right in the middle of back-to-school week, start looking ahead to the final two free entry days of 2021, Sept. 25 and Nov. 11. TPG put together the list below of less-crowded national parks and monuments that you can visit for free on those days (including two favorites that are always free to visit throughout the year). Find one that fits your schedule and interests, and go enjoy the great outdoors!

About 2.5 hours by car from Reno and less than four hours from San Francisco, this Northern California national park sees just a fraction of the Yosemite hordes. Lassen Volcanic National Park is a hydrothermal wonderland where you can spot steaming fumaroles, hook a rainbow trout or dip into a clear mountain lake over the course of a day.

Manzanita Lake is a favorite for kayaking and fishing. And the beach at Summit Lake, accessible from the main park highway, makes it easy to stop for a swim while you’re touring.

Congaree National Park

Primeval forest landscapes await at this South Carolina national park located less than 20 miles southeast of the state capital, Columbia, and about 100 miles from Charleston, if you’re coming from the coast. Entrance is always free at Congaree National Park.

The wilderness here is home to one of the country’s largest remaining intact expanses of old-growth bottomland hardwood forest and is an amazing place to see bald cypress trees, some with circumferences of more than 26 feet. The park is also a Globally Important Bird Area with spectacular biodiversity. The tree canopy is so dense in parts that Barred Owls can sometimes be heard calling in the middle of the day, so keep your eyes (and ears) tuned.

Dinosaur National Monument

Opting to visit a national monument instead of a national park can be a good bet for ditching the guidebook crowds. And Dinosaur National Monument in Jessen, Utah, is a place where the behemoths once roamed in a particularly picturesque setting.

It’s 3.5 hours by car from Salt Lake City and about 4.5 hours from Denver. In addition to seeing prehistoric dinosaur remains embedded in rocks and petroglyphs, you can go rafting through lonely canyons along the Green and Yampa Rivers within the 210,000-acre park and hike uncrowded trails where sheer cliffs tower at every turn.

Everglades National Park

With three different entrances spread across the girth of South Florida, Everglades National Park — the largest subtropical wilderness in the U.S. — makes it easy to spread out and escape any crowds (if not the alligators, more than a million of which live in Florida).

Summer temperatures in South Florida, of course, can be brutal, which does help to cut down on the park’s attendance at this time. Perhaps opt to explore via a shaded boat ride from the Gulf Coast Visitor Center near Naples or a tram ride from the Shark Valley Visitor Center instead of a full-sun stroll along the admittedly excellent Anhinga Trail near Homestead.

Wind Cave National Park

In the southwestern reaches of South Dakota, Wind Cave National Park is “one of the very best places to see bison, elk and prairie dogs without waiting in the Yellowstone traffic jams,” said Epperson. And it’s another national park that never charges an entry fee to visit yet remains uncrowded for most of the year.

The park is home to the eponymous Wind Cave, one of the longest and most complex caves in the world. It’s named for the air pressure system created by barometric winds at its entrance (yes, you can feel it!). You can enter the cave during ranger-led tours only, but there are plenty of other exterior hiking trails to enjoy, too, if that sounds a bit too claustrophobic.

Isle Royale National Park

Ferries and seaplanes carry visitors from points in Minnesota and Michigan to this splendid national park on an island in Lake Superior. An International Biosphere Reserve, Isle Royale National Park is home to beavers, moose, gray wolves, mink and many more animals – and on most days, there are far more of them than any human visitors.

You can explore via a day hike on a short visit or stay longer to paddle miles of waterways within the park that includes inland lakes, coves and bays.

Dry Tortugas National Park

Here’s another worthy hop by seaplane or boat where the national park fees are being waived over the course of six days in 2021.

Florida’s Dry Tortugas National Park makes for one of the most amazing day trips from Key West (the park is about 70 miles west of Duval Street), with some of Florida’s best snorkeling within the 100-square-mile park that’s almost entirely underwater.

The thing to see topside in the Dry Tortugas, beyond the park’s pristine strip of white sand beach, is the 19th century Fort Jefferson – a huge coastal fortress at the park made from millions of bricks that contrast to dazzling effect with the surrounding turquoise waters of the Gulf of Mexico.

The bottom line

Wherever you choose to visit within the National Park Service’s portfolio, says Epperson, remember that most people don’t stray more than 100 feet from the roadside within the national parks. “Even big popular places have plenty of places to get away,” he said. You can see the entire list of participating parks and national monuments that are waiving entrance fees in 2021 here.
