Field Trips That Don’t Cost a Fortune

The library card is the cheapest field trip pass you own

Before you buy a single ticket, walk into your local library and ask if they have a museum pass program. A lot of public library systems partner with local museums, science centers, zoos, and gardens to lend out free or discounted admission passes on your library card, the same way they lend out books.

One well-documented example is the Museum Adventure Pass in the Chicago area, where more than 160 suburban public libraries let cardholders check out a pass for free or discounted admission to 17 cultural destinations, including the Chicago Botanic Garden and the Illinois Railway Museum. Not every library runs a program this big, but a surprising number run something like it. It costs nothing to ask your librarian.

National parks and public lands: several free days a year, plus a pass just for fourth graders

The National Park Service waives entrance fees on eight days in 2026: February 16, May 25, June 14, July 3-5, August 25, September 17, October 27, and November 11. Fee-free means the entrance fee is waived. Camping fees, reservation fees, and special use permits still apply, so plan around a day hike or a visitor center, not a campground.

If you have a fourth grader in the house, look into Every Kid Outdoors. It’s a federal program (a partnership between the Department of the Interior, the Army Corps of Engineers, NOAA, and the U.S. Forest Service) that gives any fourth grader a free annual pass covering entry for themselves, all accompanying kids under 16, and up to three adults, to more than 2,000 federal recreation sites, including national parks, forests, and wildlife refuges. You get it by having your fourth grader complete a short activity on the Every Kid Outdoors website and download a voucher, good from September 1 through the following August 31.

The free museum weekend most people don’t know about

If anyone in your house has a Bank of America credit or debit card, you already have access to Museums on Us. On the first full weekend of every month, cardholders get free general admission at roughly 250 partner museums, science centers, and botanical gardens across 43 states. Some locations honor it Saturday only or Sunday only, so check the map for your specific museum before you drive over.

Military families get an extra season of free museums

For families connected to active duty, National Guard, or Reserve service, Blue Star Museums runs from Armed Forces Day through Labor Day each year (May 16 through September 7 in 2026). It’s a partnership between the National Endowment for the Arts and Blue Star Families, and it opens up free admission at museums across the country for the whole family for the summer.

Free every single day, no ticket needed

If you’re anywhere near Washington, D.C., remember that Smithsonian museums are free every day of the year, no ticket or reservation required, for every location except the Cooper Hewitt design museum in New York. That covers the National Air and Space Museum, the National Museum of Natural History, and the rest of the Smithsonian complex, plus the National Zoo. Special add-ons like IMAX films or planetarium shows can carry their own charge, but walking through the halls costs nothing.

Don’t skip homeschool days

Plenty of science centers and museums run dedicated homeschool programming, sometimes at a discount off standard admission, sometimes bundled with hands-on classes. Pacific Science Center, the California Science Center, and Science Museum Oklahoma all publish homeschool day pages with their own pricing and schedules. It’s worth a five minute search for “[your nearest science museum] homeschool days” before you pay full price at the door.

A simple system before you go

Put a recurring reminder on your calendar for the first weekend of the month (Museums on Us) and check nps.gov for that year’s fee-free dates in January. Sign up for email lists at the two or three museums your family visits most. A lot of discount days get announced by email a few weeks out, not posted where a search engine will find them. Between the library, the fee-free calendar, and a few email subscriptions, you can fill a real field trip rotation without ever paying full sticker price. We keep a running list of resources like these, verified and updated, over on our Resources page, so check there too before you plan next month’s outing.
