Celebrate National Estuaries Week with an Estuary Extravaganza at the UGA Aquarium on Saturday, Sept. 22. Estuaries are places where rivers meet the sea, causing fresh and saltwater to mix. Come face-to-face with the animals that live in our local estuaries by going behind-the-scenes of the aquarium, interacting with horseshoe crabs, and enjoying family-friendly activities about Georgia’s coastal habitats. Pack a picnic lunch to enjoy on the banks of the Skidaway River and explore our nature trail to experience the sights and sounds of beautiful maritime forest and salt marsh habitats.
