Choose your destination

Image: Annie Spratt

Unless they have a specific destination in mind, narrowing down the large list of national parks should be the first item on the list of any aspiring visitor. Fortunately, the National Park Service has a helpful section on its website called 'Find A Park,' which allows users to select a park from the list or search for parks by state, activity, or topic.

Once you've decided where you're headed, check for maps, calendars, directions, hiking trails, and operating hours. Additionally, when choosing your perfect destination, consider exploring some under-the-radar parks, which might offer more solitude and less crowded experiences.

2

Check the weather

Image: Inge Maria

Almost nobody wants to be caught off guard by rain when spending time outdoors. Therefore, always check the weather conditions in advance so you can prepare accordingly or reschedule if necessary.

Even if the weather seems favorable in the morning, a thunderstorm could roll in during the afternoon, so it’s best to be prepared.

3

Pack smart

Image: Alice Donovan Rouse

Life in nature is not the same as life in the city. As basic as that statement might seem to most, watching people attempt to hike through rocky trails in impractical footwear reminds us that perhaps it isn’t so obvious.

Therefore, when exploring nature, make sure to bring durable, comfortable gear . Essentials include hiking boots, sunscreen, waterproof jackets, and layered clothing. Even if you don't plan to be out for long, always bring essential supplies like a first aid kit, water, and snacks whenever you visit a national park.

4

Link parks together

Image: John Matychuk

Many parks in the U.S. are within a short driving distance of each other , so it is always a good idea to visit several national parks in the same area. This way, you’ll experience a bunch of different landscapes in one single trip.

5

Historic accommodations

Image: Igor Chitz

Many national parks have historic lodges within their grounds . Featuring natural materials and stunning designs, these accommodations offer a unique experience worth staying in for a night or two. Keep in mind that booking a room can be challenging, and availability may be limited.

6

Free nature

Image: Kalen Emsley

In a world where almost everything comes with a price, it’s refreshing to know that most national parks are free . And the ones that do, charge a modest fee, ranging from $5 to $35, which typically covers up to seven days for an entire carload of people.

7

Pets

Image: Jamie Street

Our furry friends aren’t always welcome in national parks. If you're traveling with pets, be sure to check the park’s policies. Many parks allow pets on leashes in certain areas , such as campgrounds, and some even offer kennels. However, it’s important to research this in advance.

8

Try to avoid peak seasons

Image: Sebastian Enrique

The summer months are typically the busiest time of year at national parks . Visiting popular parks during the off-season means fewer crowds and lower rates. October is considered an ideal time to visit most national parks, as it’s quieter and the weather is pleasant.

Even if you visit a national park during the high season, you can still avoid crowds by arriving early in the morning before most tourists or visiting in the middle of the week to avoid the weekend rush.

9

Tours and campground reservations

In the same vein as the peak season commentary, making tour and campground reservations is always a good idea. Accommodations tend to fill up early, but online reservations are easy to make . Booking in advance will ensure you get the accommodations and experiences you want.

10

Check out the visitor center

Image: Blake Wisz

While many people tend to pass by the visitor center kiosk without giving it a second glance, doing so at a national park can be a very useful stop. You can pick up maps, guides, and up-to-the-minute information on everything from road conditions to hiking trails, as well as learn about special programs offered at the park.

11

Ask the locals

Image: Taylor Flowe

Nobody knows more about the parks than the park rangers who work there every day. They are highly knowledgeable about everything there is to know about their park and are always ready to assist visitors in any way they can.

12

Keep your distance from animals

Image: Elizabeth Meyers

This should be a no-brainer, but it's worth repeating: be respectful of wild animals and keep your distance. The animals you may encounter in some national parks are not captive in a zoo. These animals are in their natural habitat and behave accordingly .

13

Respect nature

Image: harun asrori

Another simple tip: national parks are protected areas where the preservation of nature and entire ecosystems is critical. Therefore, it's essential to follow all park rules during your visit , including staying on designated trails, respecting wildlife, not littering, and being considerate of fellow travelers. This way, national parks will continue to thrive for generations to come.

14

Be mindful of campfires

Continuing with the obvious tips, we can't leave this one out: unattended campfires pose a serious threat. Help prevent forest fires by never lighting campfires in prohibited areas and always ensuring that authorized fires are properly extinguished.

15

Embrace the digital disconnect

Image: Philip Smart

National parks are places where visitors go to connect with nature, not with their cell phones. Besides, cell service in these areas is often limited. The last tip on this list is always an obvious one, at least for us: put your phone aside and experience the world with your own eyes , which have a much better quality than the best phone ever built.

1

Home economics class

Home economics as a school subject peaked in the mid-20th century, teaching sewing, cooking, and budgeting —often aimed at girls.

By the 2000s, however, many states had folded it into a broader "family and consumer sciences" category, as shifting gender roles and changing cultural habits made the old curriculum feel increasingly outdated.

2

Woodshop in every school

Lightly supervised children with access to power tools? Today, it seems hard to believe, but woodshop was a standard industrial arts course throughout the 1950s–1980s.

Declines began in the 1990s due to higher liability insurance costs, budget cuts, and a growing emphasis on college-prep academics over practical skills. Some schools still maintain limited woodworking programs, often using them as hands-on, integrated learning tools.

3

The dodgeball era

Dodgeball dominated physical education classes well into the 1990s, often using hard rubber balls that were notorious for causing stingers, bruises, and occasional injuries . The game was popular because it required little equipment, could fill an entire class period, and kept large groups of students active.

By the 2000s, however, concerns about safety and bullying led many districts to restrict or replace dodgeball with more structured team sports. Some schools still play modified versions, usually with soft foam balls and strict rules.

4

Chalkboard dusting

For over a century, green and black chalkboards were the centerpiece of American classrooms, with students regularly assigned to "clap out" erasers outside to clear the built-up dust. Chalk was cheap, durable, and easy for teachers to use in large rooms.

By the 1990s, districts began replacing chalkboards with whiteboards due to dust concerns linked to asthma and indoor air quality. The shift accelerated as overhead projectors, digital displays, and interactive whiteboards provided cleaner surfaces and reduced inhalation hazards.

5

Daily milk breaks

Mid-morning milk breaks became common in American elementary schools after the USDA expanded dairy subsidies through programs like the Special Milk Program in 1954. For decades, students lined up for small cartons—usually whole milk—intended to boost childhood nutrition and support U.S. dairy producers during periods of surplus.

By the 1990s and 2000s, milk breaks declined as updated nutrition guidelines shifted schools toward broader meal programs rather than standalone milk service.

6

In-school smoking lounges

The idea of teens openly smoking on school grounds would be almost unimaginable under today’s health and liability standards. But through the 1960s and into the early 1980s, many American high schools—especially in the Midwest and Northeast—maintained designated smoking areas for students.

The practice disappeared quickly as federal and state regulations tightened, beginning with widespread adoption of indoor smoking bans in the late 1980s and early 1990s. The 1994 Surgeon General’s report and anti-tobacco campaigns further pushed districts to eliminate student smoking sections altogether.

7

Daily cursive drills

For most of the 20th century, daily cursive drills were a nonnegotiable part of American schooling , often reinforced by specific handwriting manuals. Teachers devoted significant class time to perfecting loops, slants, and connected strokes, because cursive was considered essential for legibility, speed, and personal discipline.

The decline accelerated after the rollout of the Common Core State Standards in 2010, which omitted cursive entirely in favor of keyboarding and digital literacy benchmarks. With shrinking instructional time, cursive was often one of the first skills removed from early-grade schedules.

8

Class pet enclosures

From the 1960s through the 1990s, class pets—hamsters, guinea pigs, turtles, goldfish, and even the occasional lizard—were staples of American elementary classrooms. Teachers used them to teach responsibility, empathy, and basic biology , and many classes created rotating "pet helper" charts for feeding and tank cleaning.

Today, the idea of a live animal in a crowded classroom, handled daily by students, feels out of step with modern safety, allergy, and sanitation standards. Maintenance costs, humane-treatment rules, and the challenge of caring for animals during breaks led schools to retire these longtime classroom mascots.

9

Student hall monitors

For much of the mid-20th century, student hall monitors were a fixture in American schools. Selected students—often upper-grade or high-performing—wore badges or sashes and were tasked with checking hall passes, reporting loitering, and keeping noise down between classes.

By the 1990s, the role faded as schools adopted professional security staff, stricter attendance protocols, and legal liability rules that made peer enforcement impractical. As districts invested in cameras, campus supervisors, and centralized discipline systems, the traditional hall monitor quietly disappeared from most American schools.

10

Morning physical calisthenics

From the 1950s through the early 1970s, influenced by Cold War fitness campaigns, many American schools began the day with school-wide calisthenics —jumping jacks, toe touches, and arm circles—led over the PA system.

The practice faded as schedules tightened and PE moved into dedicated class periods, with research favoring structured fitness over brief daily routines. Today, the idea of entire schools performing synchronized drills feels almost militaristic.
