7. NY City Explorers
Location: 186 Underhill Avenue
At the 7th spot in our list of indoor play spaces and kiddie gyms in Brooklyn is the NY City Explorers play space that isn’t one of those that you can visit once and pay just for one day. If you want your kid to play in their wonderland, you will need to purchase one of their packages, which by the way aren’t that bad. For $90, you will get ten-day passes or a seasonal pass for just $335. Shortly after the first visit, your kid will fall in love with this place, and he or she won’t want to leave.
