National Estuaries Day is almost here!
The St. Lucie County Aquarium is celebrating with expanded programming on Saturday, September 26. Join us to take a deeper dive into the Indian River Lagoon - no snorkel needed!
Before the Aquarium opens, meet us on the porch at 9:00am for a beach clean-up. Our team will provide all the gear you need to comb South Causeway Beach and make sure we keep our lagoon beautiful.
Once the Aquarium opens at 10:00am, get ready for opportunities for discovery every hour!
10:30am & 2:30pm - Join one of our Educators for our ever-popular feeding tours! The tour will start at the Seagrass Exhibit and visit each model ecosystem in the Aquarium as the critters get their breakfast.
11:30am & 3:15pm - Ready to discover the unseen? Meet on the Aquarium’s porch and walk out to the docks with an educator to collect tiny plankton from the Lagoon. Then, head back inside to see the catch of the day under our microscopes!
12:30pm & 1:30pm - Prepare to get wet! Join our educators as you head into the Lagoon right outside of the Aquarium. Work in small teams to drag long nets through the seagrass beds to safely collect small fish, crabs, and other invertebrates – then release them back into their habitat! Parents are required to be in the water with their children, and close-toed shoes with a heel strap are required!
National Estuaries Day is included with regular Aquarium admission: $5/adult, $4/child (4 - 17), $4/senior (55+), and free for children under 4. The Aquarium will be open for standard operating hours, 10am - 4pm.
