Summer fun really heats up this weekend with a bunch of outdoor festivals including two of our top picks for all of June: the action-packed Ultimate Science Street Fair in Washington Square Park and the multicultural celebration Drums Along the Hudson in Inwood Hill Park, and both are 100% FREE.

Other cool activities include a FREE concert by Morgan Taylor (a.k.a. the man behind Gustafer Yellowgold) and astronomer-led stargazing, both in Brooklyn Bridge Park. Plus, an interactive high-tech show premieres at the New Victory Theater.

These are just a few of the great things going on this weekend. All of our best bets are below. You can find additional options in our Event Calendar and our Summer Fun Guide.

A Long Island summer's in full swing; and while we definitely want our kids to have fun in the sun, many parents are concerned about their children losing all that they've learned over the school year. Fortunately, there are many enrichment programs across Long Island, all designed to avoid the dreaded "summer brain drain." Students can not only improve their reading, writing and math skills, but also explore interests in art, music, science, and more. And for other programs for kids, check out our Long Island Classes and Enrichment Guide.

After a rainy and chilly spring, I think it’s safe to say that most of us are jumping for joy that summer is finally here! Get a head start on summertime activities this weekend, whether you try your hand out with bait and a pole during My First Fish at Turkey Swamp Park, bring the whole gang to watch jugglers and sword fights at the NJ Renaissance Faire or venture down south to the Horseshoe Crab Festival in Fortescue. Looking for a little entertainment?

Yonkers is a fantastic city teeming with things to do for kids and families. So far this month, we've shared the best of what Yonkers has to offer families, including picturesque parks, green spaces and nature trails, as well as a dozen indoor destinations for families.

Now onto the thing I happen to love most about Yonkers--the shopping! I might be dating myself, but I remember my mother taking me shopping in Yonkers (Alexander’s anyone?) and now it’s one of my must stop shopping destinations for my daughter. When shopping for kids (and adults), Yonkers has it all. We are shining the spotlight on three premier shopping destinations in Yonkers that not only offer toys, shoes, clothing, games and more, but also places to play, kid-friendly restaurants and exciting events held all year round! So read on for Yonkers’ hottest children’s shopping spots and make a day out of it with the entire family.
