Just because we live in a concrete jungle doesn't mean our kids can't enjoy a summer filled with great outdoor spots. And you don't even need to be a Hilton to afford them.

New York City offers many opportunities for city kids to learn team sports and also try swimming, tennis, golfing, fishing, kayaking, hiking and more at no cost. Of course registering for these free programs takes a little legwork and, since many of them are first-come, first-serve, punctuality. We've got the scoop on what's available, and how your kids can vie for spots.

Originally developed in the early 20th century as an upscale residential neighborhood before it fell on hard times, Crown Heights, Brooklyn is in the midst of a revival. It's no surprise really. The area boasts top cultural institutions like the Brooklyn Museum, the Brooklyn Children's Museum and the Brooklyn Botanic Garden; the northeastern section of Prospect Park, which includes the zoo; and lots of lovely buildings, especially near its main thoroughfare, Eastern Parkway (which, like Prospect Park, was designed by Frederick Law Olmsted and Calvert Vaux).

While Crown Heights was emblematic of New York City's racial tensions in the '60s through '90s, today its diversity is one of the things attracting new residents. Though the neighborhood is still primarily made up of Afro-Caribbeans and Hasidic Jews, families of all ethnic backgrounds are moving into townhouses and joining the active Crown Heights Parents Yahoo Group, new shops and restaurants are opening up, and local organizations are working hard to keep everyone happy. Stark contrasts remain, with pretty rows of historic houses giving way to vacant tenements on some blocks. But overall it's a vibrant area, especially around Labor Day weekend when Crown Heights hosts one of the biggest and most colorful festivals in the city: The West Indian Labor Day Carnival and Parade, which celebrates Caribbean culture with incredible costumes, performances and two processions, one for adults, the other specifically for children.

Throughout May, we'll be taking an in-depth look at everything Crown Heights has to offer families, including our favorite spots to eat, play and experience. For the purposes of our posts, our geographical boundaries are Washington to Howard Avenues, between Atlantic Avenue and Empire Boulevard (which transforms into East New York Avenue at Utica Avenue). Today we kick off our coverage with our top 25 things to do with kids in Crown Heights, Brooklyn.

I admit it: Mini golf is one of those things I endure for the sake of my son. I never enjoyed it as a kid and I don’t love it as an adult, but my kid could play every day. I know that for many families, mini golf is a quintessential warm weather activity that they look forward to every year. And spring is definitely a great season to play before the summer humidity kicks in.

While there are plenty of courses on Long Island and in New Jersey , you don't need to head out of town for putt-putt golf. There are currently a dozen places to play mini golf right here in New York City (including one indoor course), complete with spinning windmills, bridges, water features, you know, the works. Even the course at Pier 25 in Hudson River Park, which was closed due to damage caused by Hurricane Sandy, has reopened.
