St. Lucie County Aquarium Adds Monday Hours

January 13, 2023

The St. Lucie County Aquarium, featuring the Smithsonian Marine Ecosystems Exhibit, is back to being open seven days a week.

Operating in partnership with the Smithsonian Marine Station, the St. Lucie County Aquarium houses more than 8,000 gallons of marine life that accurately reflect the habitats and sea life found in the Indian River Lagoon and Atlantic Ocean.

Admission into the aquarium is $4.25 for adults; $3.25 for seniors (55 and older) and children 4 to 17 years old and children under 4 are free. The first Tuesday of each month is free admission day.

The St. Lucie County Aquarium is open (January – March) Monday through Saturday from 10:00 AM to 4:00 PM and Sunday from noon to 4:00 PM; however, the Aquarium will be closed on Monday, January 16, 2023, in observance of the Dr. Martin Luther King, Jr. Holiday.

With help from volunteers and staff from the Smithsonian, the aquarium offers a variety of programs from behind-the-scenes tours and feeding demonstrations to coastal cleanups. For a full list of events, visit
