Visiting

• Address: 102 Bienville Blvd, Dauphin Island, AL 36528 — east end, at the Dauphin Island Sea Lab.
• Phone: 251-861-7500
• Parking: free, on site.
• Also known as: the Estuarium. Same place — the name changed.
• Find it: from the bridge, take a left at the water tower; the aquarium is about two miles on the left.

Admission is ticketed and prices and hours shift with the season, so check with the aquarium directly rather than trusting a figure from an older guidebook — including this one.

Four habitats, one building

What makes this worth an hour of a beach trip is the structure. Rather than a random collection of tanks, the aquarium is organised around the four environments that make coastal Alabama unusual, and you walk through them in order:

• The Mobile-Tensaw River Delta. Where the freshwater comes from — one of the largest river deltas in the country, and the reason the bay is so productive.
• Mobile Bay. The estuary itself, including the big central tank and the animals that live around Middle Bay Lighthouse.
• The barrier islands. The environment Dauphin Island is part of — dunes, maritime forest and the sand that moves.
• The northern Gulf of Mexico. Open water, and the species that pass through it.

Along the way there are touch pools, where stingrays are the reliable draw for children, and a Living Marsh Boardwalk outside that shows the marsh as working habitat rather than a exhibit behind glass.

Is it good with children?

Yes — this is one of the better small-aquarium experiences on the coast precisely because it is small. A child can see all of it without the meltdown that comes at the end of a four-hour theme-park aquarium.

• Length: one to two hours is realistic.
• Touch pools: the highlight. Check the day's schedule for feeding and touch times.
• Rainy day: this and the fort are the two reliable indoor-ish options on the island.
• Ferry waiting: it sits a short drive from the ferry landing, which makes it a natural stop if you are crossing to Fort Morgan.

House rules, briefly

No pets — service dogs as required by the ADA and Alabama law are the exception. No firearms. No open containers. Shirts and shoes required, and no bikini tops. These are enforced, so plan your beach-to-aquarium pivot accordingly.
