The Children’s Museum of St. Tammany inspires children to imagine, explore, and create in an interactive learning environment.
CMST opened its doors in 2018 to provide a vibrant, hands-on learning landscape where play and education merge. Serving St. Tammany Parish and surrounding communities, we focus on early childhood development, creative arts, and immersive STEM (Science, Technology, Engineering, and Math) experiences.
Through interactive galleries like Natural Wonders, ARTworks, and Little Lake Tots — each packed with hands-on exhibits — we offer children the tools to discover new concepts, build confidence, and grow a lifelong love of learning.
What parents and grandparents love about the Children’s Museum
“Very cute museum. It's not that big but they have lots of activities. The staff were very friendly. Would definitely recommend for little kids”
“Love the new location! Everything flows better and the kiddo's have more room to move around and play. After our first visit to the new location we got a year pass. My daughter always looks forward to going here on the weekends or when school is out.”
“My 2 year old loves the interactive play stations at the new children's museum in Mandeville. It is the perfect blend of art, fun, and education. I highly recommend it for your young children.”
“My three-year-old granddaughter had so much fun she didn’t want to leave. I was impressed with the many different activities from creative art, puppet stage, grocery, kitchen, stem activities. An incredible use of space. The staff was great and friendly.”
Thank you to the organizations that support interactive learning in St. Tammany
