About Our Freshwater River
Our freshwater river is the centerpiece of our beautifully landscaped campus. Walk along the freshwater river from the top of the boardwalk down to our lower dolphin area. Check out the different species of freshwater fish and reptiles, including catfish, paddlefish, yellow belly sliders, and large alligator gar with unobstructed views.
See if you can spot Scrub, our 80-pound resident alligator snapping turtle, as it makes its daily trek from upper river to lower river. Or just relax near a waterfall and enjoy all of the beauty of our campus and the skyline of Downtown Gulfport.
