Go apple picking

Apple picking combines outdoor fun with delicious and healthy snacks that can be used in a variety of ways, making it the perfect fall activity for adults and children of all ages. Though you'll find countless orchards around the country worth visiting this season, New England is widely considered a prime apple picking destination with over 120 varieties found in the region. It can be argued that the variety they are best known for is the McIntosh apple. This type of apple and many more can be found at Honey Pot Hill Orchards in the lovely town of Stow, Massachusetts, so be sure to stop in and take home a bushel that you pluck from the trees yourself. Picking times are from 9 a.m. until 6:00 p.m. daily, making it easy to schedule a trip.

Meanwhile in California, apple season runs until the end of November, giving you plenty of time to pick a few baskets of Red Delicious or Gala apples before winter. Riley's at Los Rios Rancho in the city of Yucaipa is one of the largest farms of its kind in Southern California and has been welcoming apple pickers to their 10,000-tree farm for more than 100 years.

Visit a pumpkin patch

If there was a fall mascot, it would be a pumpkin, so to celebrate the true essence of the season, it's hard to beat a trip to a colorful pumpkin patch. A pumpkin patch is more than just a place to find the perfect candidate for this year's prize-winning jack-o'-lantern, it's a wonderful way to create cherished new memories with your children or friends. The Great Pumpkin Farm in Clarence, New York, is perfect for pumpkin picking, but also offers weekend activities throughout the fall, including scarecrow making lessons, cider brewing demonstrations, pumpkin pie eating contests, and live music and barbecues.

If you're traveling through the Midwest this season, hop aboard a vintage farm wagon at Polly's Pumpkin Patch in Chilton, Wisconsin, and make your way out into their scenic fields where you can pick as many pumpkins as you want. Other activities at Polly's include a livestock petting zoo, a 40-foot slide and a popular corn cannon that lets older kids launch corn cobs at targets for cash prizes.

Enjoy a harvest festival

An annual tradition in America that dates back to 1613, harvest festivals are outdoor celebrations that coincide with the growing and reaping seasons we all enjoy. Filled with food, fun, music and dance, you haven't truly experienced the wonder of the fall season until you've participated in a local harvest fest. The good news is that there are plenty to choose from around the country this year. Two of the most popular are the Autumn at the Arboretum festival in Dallas, Texas, which runs until October 31, and the incredible North Carolina Pecan Harvest Festival in Whiteville, North Carolina, which ends on November 3. Both of these festivals have been drawing huge crowds for years.

For a harvest fest that's slightly spookier, head to Wisconsin where you'll find the classic Jack O' Lantern Days celebration in the cozy town of Fish Creek, and the Halloween-themed Zombie Days festival on the coast of Chequamegon Bay. Ghoulish activities include an undead musical show, a zombie pub crawl and a traditional harvest festival pumpkin parade. The scary fun lasts from October 26 through October 27.

Hit the trails

Hiking is more than just great exercise; it's an excellent way to bring the whole family together during the fall. And since the leaves are changing colors, it's also a great way to snap some incredible nature photos. So lace up your hiking boots, grab your kids and your camera, and find a trail that's right for you. If you're looking for suggestions, Sterling Point Trail in Vermont and Rome Point Trail in Rhode Island are impossible to beat when it comes to picturesque fall hiking.

On the opposite side of the country, the trails at Dry Creek Falls in Portland, Oregon, were voted one of the most photogenic hiking spots on the west coast by BuzzFeed, and it's easy to see why once you've been there. Covering a distance of just over 4 miles, this beautiful trail is perfect for all skill levels, making it a solid choice for families with kids.

Roll in the hay

Hayrides and corn mazes are traditional fall activities that have never gone out of style, and for very good reason. There's just something wonderfully nostalgic about introducing a new generation of children to the simple pleasures of wandering through an overgrown corn maze, and with so many participating farms scattered across the country, there's a plethora of options to choose from. The Johnny Appleseed corn maze at Shady Brook Farm in Yardley, Pennsylvania, and the popular horse-drawn hayride at Papa's Pumpkin Patch in Bismarck, North Dakota, are two of the best.

In honor of Halloween, the massive haunted hayride at Fear Farm in Phoenix, Arizona, brings an assortment of ghosts, goblins and ghouls to life from early October until the first week in November. Filled with sinister special effects, creepy costumes and macabre makeup, this Hollywood-worthy hayride is recommended for adults and children over the age of 12. With five terrifying corn mazes to choose from, Fear Farm certainly lives up to its name!

Up, up and away

Hot air ballooning during the fall is a dazzling way to experience the season in all its natural splendor. After all, how else can you get a spectacular birds-eye view of the colorful trees as their leaves change from green to golden orange? Balloons Over Letchworth, located near New York's Letchworth State Park, offers astonishing views of the surrounding area, including majestic waterfalls and stunning forests. Best of all, they offer a variety of family tour packages, so you'll find just what you're looking for, regardless of the size of your group.

If you're visiting Southern California's wine region this fall, reserve a balloon ride with the fine folks at California Dreamin'. Their friendly FAA commercial licensed pilots will take you and your family on an unforgettable balloon voyage high above the vineyards of Temecula wine country.

Pitch a tent

Though typically associated with summer, in many ways the fall is truly the best time of year to go camping. Thanks to the cooler weather, there are few — if any — insects to bother you and your family. Plus, there are less people claiming all the best spots, so you should have no problem picking a prime location to pitch your tent. And when it comes to toasting marshmallow for s'mores over an open campfire, everyone agrees that they simply taste better when eaten on a brisk autumn night.

For the ultimate fall camping trip, book a spot at Earth First Farms in southwest Michigan and set up your tent in an actual organic apple orchard. The 49-acre farm provides campers with complimentary firewood and plenty of fresh produce to pick.
