About CMST + Our Mission
The Children’s Museum of St. Tammany inspires children to imagine, explore and create in an interactive learning environment and envisions a community where play is encouraged, creativity is nurtured and learning is enjoyed.
Visitors tackle challenges and solve problems, exploring the big questions about their natural and man-made world.
Visitors challenge themselves physically as they navigate the large oak tree that will take them to the top of their climb.
ARTworks encourages exploration of ideas and interests and interaction.
Inspired by Lake Pontchartrain, this area provides our littlest visitors with a safe place to explore.

My son had an amazing time learning and creating! Very friendly and courteous staff!
So clean and cute as can be! Enjoyable for children as young as one! We will definitely be going back! So happy to have a place like this so close to home!
It's adorable! My 6yr old and 3yr old stayed for hours and had a SUCH a blast!
