Public Aquarium


The public Aquarium is an exciting educational venue highlighting the four key habitats of coastal Alabama: the Mobile Tensaw River Delta, Mobile Bay, the Barrier Islands, and the Northern Gulf of Mexico. It includes the 10,000 square foot Exhibit Hall, a 7,000-gallon stingray touch pool, and the Living Marsh Boardwalk. This facility has 31 aquariums totaling over 30,000 gallons with more than 100 species on display. The Aquarium showcases the plants, animals, and other natural resources found in the estuary and its surrounding marine habitats.

Through beautiful visual exhibits and engaging interactive exhibits, the aquarium will leave you with a broader understanding of the interactions that take place in Mobile Bay, the fourth largest estuary system in the United States.

DISL reserves the right to cancel in case of inclement weather or if there is insufficient participation.

Salt marshes are not monotonous expanses of grass; they’re fascinating coastal wetlands that are critical to our estuary system. Be a marine scientist for a day, and use seine nets, buckets, shovels, and sieve boxes to collect samples, including crabs, snails, and fish (we’ll release animals back to the marsh). You’ll learn about the important role salt marshes play in the Gulf of Mexico and how they support the seafood we enjoy.

After meeting at the Estuarium, you will travel to the Dauphin Island salt marsh to explore this vital ecosystem. Please be advised that you will get wet and muddy, so you may wish to prepare your vehicle accordingly.

What to wear:  Proper footwear is very important for your safety and enjoyment. Because of sharp oyster shells, participants are advised to wear closed-toe shoes that tie or strap on, such as old tennis shoes. Please no flip-flops, Crocs or rubber boots as they get ‘eaten’ by the marsh mud. Wear clothes that can get wet and muddy. Showers and changing facilities will be available after the marsh trip.

What to bring:  hat, sunscreen, water bottle, change of clothes and shoes, bag for muddy items


2020:  June 2, June 18, June 24, July 7, and October 1

DISL reserves the right to cancel in case of inclement weather or if there is insufficient participation. 

There’s more to a barrier island than sand and water – the beach is a thriving habitat with a dynamic dune system and fascinating plants and animals, and higher elevations are covered by lush forest. We’ll walk through the maritime forest, then on to the dunes and beach.

You will learn about plants that Indians and colonists used and the benefits of an intact dune system. You’ll see many coastal animals; occasional highlights include osprey, alligators, and dolphins. You’ll dig for mole crabs that live in the surf zone and chase scuttling ghost crabs. We’ll bring hand nets and critter containers so we can get an up-close look.

What to wear:  Comfortable walking shoes for the beach and forest. Light-weight clothes for hot summer temperatures. If you’re eager to get wet, feel free to dress accordingly, though getting wet can be avoided.  

What to bring:  hat, sunscreen, water bottle, bug spray, change of clothes and shoes, bag for wet items
