As the school year comes to a close and extracurricular activities wind down, the festival, fair, and carnival season is just getting started! We've compiled a list of all the great festivals and fairs happening this June. From the once-in-a-lifetime opportunities to annual traditions, there is something for every member of the family. So, get out your calendar and be sure to make time for the array of fun that awaits Philly families this month!

So maybe you've heard about it but you're still not really sure. What is letterboxing anyway? Well to start, it is really like the ultimate scavenger hunt. You are given a set of clues and then you head out into the woods and go on a hunt in search of secret hidden stamps in the forest. Sound fun? That's because it is! Even my three year old is a letterboxing-enthusiast.

This fun family adventure is great for all ages and for all cities located across the country. There are about 90,000 active letterboxes hidden in North America alone. So what exactly is a letterbox? Letterboxes are small weatherproof boxes that typically contain a hand-carved rubber stamp, a log-book to keep a record of visitors, and occasionally an ink pad. Letterboxer's will leave an imprint of their own personal stamp in the letterbox's log book. We've rounded up six kid-friendly letterbox trails in Fairfield County. Happy Trails.

There's no other way to say it: my 9-year-old is obsessed with Minecraft. OBSESSED. He plays the game on computer, iPad, or Xbox, depending on his companions. He watches the YouTube videos (carefully curated by me, of course). He wears the T-shirts. He reads the books (there are a surprising number of them, both fiction and nonfiction).

Admittedly, sometimes we struggle with screen-time boundaries, so I've been looking for ways that he can play Minecraft productively—or at least collaboratively—to keep us both happy. There are lots of educational Minecraft opportunities in Fairfield County. Many libraries offer free Minecraft clubs (though children are usually required to bring their own laptops), and some camps have themed sessions, too.

Governors Island has long been one of our favorite places to play and the summer fun is about to get a lot more thrilling on the isle.

Adventures at Governors Island, a new high-octane entertainment zone boasting a zip line, 3-D climbing wall, and maze debuts this Memorial Day weekend (weather dependent), and we can't wait to check out the exhilarating attraction. Its opening will double the number of zip lines in NYC—to two.

The historic community of Northport lies on the north shore of Long Island. With its walkable Victorian Main Street, family-friendly restaurants, bars, shops, and theaters, it has become a destination for Long Islanders and visitors alike.

And it's not just a summer destination. In the autumn, Northport hosts Halloween fun nights, and during the holiday season the community comes alive with holiday house tours and seasonal celebrations.

Here are our suggestions for 20 things to do and see in Northport with kids, and a few bonus picks for the surrounding areas.

Summer is the perfect time to head outdoors for easy, cheap, and fun activities like free movies and concerts. Pack your chairs, a blanket, a picnic basket and the bug spray, and enjoy an afternoon or evening of free tunes. Here's our comprehensive list of the outdoor concerts happening in the Delaware Valley this summer.

For some of the more popular bands, the venues can get packed, so plan on arriving on the early side.

One thing about Los Angeles - it's not a one-parade town. If festivals are too stationary for you, if you need a parade to drum up an appetite for that Memorial Day BBQ, then you've got it made in the shade (as long as you've found a shady spot for your  chair) in Los Angeles and Orange County on Monday. The good news for the parade abstainers is that none of the parades on this holiday marches down a major thoroughfare (unless the 405 gets shut down - in which case Topanga is going to hear plenty of honking that isn't for peace). For parade fans, the patriotic fanfare never sounded so good.
