Washington, D.C.

For a summer visit to D.C., you better be ready to share it with a whole lot of field trips and tour buses. When school is pack in session, however, it’s easier to get around. For a requisite tour of the Mall, you’ll definitely want to check out our insider’s guide. For the under-five set, you won’t want to miss the Building Museum. If it’s still hot in October (it’s been known to happen), cool off in the extra-large splash fountain at the Yards Park, where the newly developed waterfront has great spots for lunch, too. If it’s already chilly when you visit, tour the U.S. Botanic Gardens and warm up among the tropical plants and flowers.

Insider's tip: All Smithsonian museums are free! That includes the National Zoo!

Disneyland—Anaheim, CA

There may not be a more magical way to take advantage of a school-free schedule than at a Disney park. At Disneyland, the weather’s just about always lovely, so find out when your school district has its winter or spring breaks—and book your family’s trip before or after to lessen the crowds. You may think it’s a trip to save for when the kids are a little older, but there is plenty for all ages to enjoy—and this may be the stage when the kids are most willing to believe in all the magic. We know how expensive it can be, too, so we have tons of ways to save so you can feel like you’ve made the most of it.

Insider's tip: We rounded up 16 hidden secrets of Disneyland (like where to pick up those baby essentials you may have forgotten at home).

Boulder, CO

One (of many) fantastic things about a high-elevation destination is all that can happen in a day just when it comes to weather. If you need a fleece in the morning during the fall months, you’ll be in a t-shirt by the afternoon thanks to your proximity to that glorious sun. And much of what is wonderful about Boulder in the summer is still accessible to families in the fall, from letting the tots scale the boulders in Arapahoe Ridge Park to a kid-friendly hike by the Flatirons. Football season, of course, is only in the fall and is when downtown Boulder is the stage for Pearl Street Stampedes. The University of Colorado's Golden Buffalo Marching Band performs while cheerleaders dance and the football team tosses out toy footballs from an antique fire truck that leads a parade. Locals and kids alike call this a favorite fall tradition. Check out all of our other favorite mountain towns to explore year round here.

Insider’s tip: If you visit right after school is back in session, you’ll have Boulder Creek more to yourself for warm-weather tubing!

Adirondack Park—Northville, NY

When the playgroup asks if you went to the park on your trip Upstate, your tots will be able to say that, yes, in fact, they visited the biggest park in the country. Well, the continental United States, but who’s counting? (If you are counting, however, the park—not to be confused with a state or national park—boasts 6,000,000 acres!). And in the fall, that adds up to a lot of changing leaves. If the kids fell asleep, you won’t even have to get out of the car for one of 14 drives that meander through some seriously epic fall foliage. For other favorite places around the country to see fall colors, check out our list.

Insider's tip: There is wildlife galore to keep an eye out for: moose, fox, river otters, flying squirrels, beavers, skunks and black bears! Did we mention flying squirrels?

Bethany Beach, DE

If you live in the Mid-Atlantic region, you know summer at the beach can mean big crowds and tons of traffic. But if you wait until fall, the beach can be yours. Even during peak season, Bethany Beach is a lower-key choice than big regional draws like Rehoboth or Virginia Beach. Both the Boardwalk and main drag of Garfield Parkway are easy strolls for short-legged travelers, with plenty of souvenir stores still open and places to duck into for French Fries or ice cream. Bethany Beach also decks out its streets for the season, making for a sweet photo-opp with pumpkins and fall decor. And if the wind picks up, just pop into Bethany Beach Books and while away some time in its darling children’s section.

Insider's tip: Tidepool Toys & Games right on the Boardwalk is a great place to grab marked-down beach toys, and they have a well-stocked Thomas the Train table inside to keep toddlers entertained.

White Sands National Monument, NM

The U.S. is rich in natural wonders, and every single state has amazing national parks to explore. Most will have fewer crowds to contend with when you avoid traveling in the summer months, but that can also put you into some inclement weather depending on when you travel. The southwest is a good bet in the fall to avoid crowds and the highest temps! And instead of miles to hike (which can be a lot to ask of the under-five set), White Sands National Monument in southern New Mexico has acres of soft sand dunes! So pack or purchase a sled at the Visitor Center, slather on the sunscreen, and slide on down—again and again, as your tot is bound to want to do! There are also kid-friendly boardwalks for exploring the dunes without getting sand in your shoes. If you’re looking for family-friendly national parks in another neck of the woods, check out our whole round-up of the best national parks for families.

Insider's tip: Hours do vary depending on the time of year, so check the website before you go.

Great Wolf Lodge—Nationwide

You may think your kids need to be mermaids to fully take advantage of an indoor waterpark like Great Wolf Lodge. But rising swimmers and life vest-wearing tots can splash-a-plenty in the areas designed especially with toddlers in mind, like the zero-entry Cub Paw Pool and Fort Mackenzie’s splash pad. With 19 locations currently across the country, from Grapevine, TX to Manteca, CA, there’s likely a lodge near you. 

Insider's Tip: You can start the fun three hours before check-in and keep it up ALL DAY after your 11 a.m. check out. That’s right, the lodge is still yours until closing (or at least until nap time, a perfect time to hit the road with a happily exhausted pack). Talk about a paw-some perk.

Mount Rainer, WA

New England, while stunning, certainly doesn’t have the market cornered when it comes to breathtaking fall foliage. If you check out Mount Rainier in the fall, not only will the summer mountaineering crowds have died down, but there will also be a blanket of reds, yellows, and greens laid out at the base of the mountain. There’s an 800-year-old Douglas fir log to checkout, the Trail of Shadows is recommended for tot trekkers (it’s under a mile), interactive exhibits await at the local visitor centers, and a gondola ride is a must. You’ll marvel at all the incredible views along the way.

Insider's tip: If your littles aren’t quite mountaineers, there is still so much to do thanks to these inspiring itineraries for families, whether you have 10 hours or 48 to explore.

Indiana Dunes, IN

If you want the beach without big waves or a coastal current, consider a jaunt to Lake Michigan, particularly the Dunes region comprised of Ogden Dunes, Dune Acres, Porter Beach, and Beverly Shores. It’s the perfect spot for picnics, pristine beaches (public as well as private beaches for those who rent a house in one of the beachside towns), and all that wet, sandy good fun that’s usually a crowd-pleaser with kids of all ages. If you’re curious about other under-the-radar beaches to visit, we gathered plenty across the country.

LEGOLAND Florida Resort—Winter Haven, FL

Whether they’re still loving DUPLOS or have moved on to a full-on brick storage station, they will absolutely love LEGOLAND, which is a good size for younger brick builders. And everyone should love the more amenable Florida weather in fall or winter months. Theme park planning is overwhelming, we know, so we’ve done all the research for you, with LEGOLAND Florida Resort secrets you probably don’t know, from “tot spots,” which are just like the big kid rides but sized for younger kids, to how autism-friendly the park is. While you have the option to stay onsite at LEGOLAND Hotel, across the road is LEGOLAND Beach Retreat, for that perfect mix of themed fun for the kids and relaxation for the ‘rents. Tot-friendly accommodations include kid-friendly menus (breakfast is included!), floating bricks in the pool, a big play structure, and even toilet seats that convert to a smaller size in the bungalows. If you’re planning to check out other LEGO locations, we have you covered there as well.

Insider’s tip: There’s a free shuttle service to the park, where you also get early admission as guests of the Beach retreat so you can beat the crowds that way too.
