Read What These Visitors Had to Say

Our four-year-old son loves this place so much that he went 3 times in one week and had a blast each time. I loved their reading time they have several times a day as well. Kate N.

My son had an amazing time learning and creating! Very friendly and courteous staff! Jolie E.

Great location for wide-open nature exploration, clean bathrooms, clean grounds...Clean, organized, costumes, puppets, sensory, art, nature, fine and large motor skills, and really fantastic! We were so happy with how the day unfolded. Although this building is smaller than we expected, it’s what’s inside that counts. The difference between busy downtown NOLA and the Northshore's peaceful charm is clear. It’s a perfect day out for you and for your younger kids whether you stay an hour or all day.
