Dauphin Island By Boat: Shrimp Nets, Sand Island Light, and Dolphins on the Bow
All Ages • 3 Hours — A hands-on cruise from Dauphin Island Marina to Sand Island Light
You can feel Mobile Bay before you see it: a briny breath that loosens your shoulders and an expanse of horizon that refuses to be corralled. The Duke slips away from Dauphin Island Marina on a morning that smells of low tide and coastal grass; gulls wheel like punctuation marks against a pale sky. Within minutes the mainland melts into a low ribbon of marsh, the boat’s wake chiseling patterns behind us while the crew talks quietly about where the dolphins like to work and how Sand Island Light kept watch over these waters for more than a century.
Trail Wisdom
Sun Protection
Bring a wide-brim hat, sunscreen, and polarized sunglasses—glare off the water intensifies UV exposure.
Motion-Sickness Prep
If you’re prone to seasickness, take preventative medication or choose a mid-day trip when the bay is often calmer.
Camera & Binoculars
A zoom lens (200–400mm) or compact binoculars will help you capture dolphins and shorebirds without crowding them.
Respect Wildlife
Observe dolphins and seabirds from a distance—do not feed or touch wildlife and follow crew guidance.
Local Knowledge
Hidden Gems
- •Indian Shell Mounds—ancient oyster-heap sites visible from the water
- •Audubon Bird Sanctuary on Dauphin Island—excellent for post-cruise birding
Wildlife
Bottlenose Dolphin, Brown Pelican and migratory shorebirds
Conservation Note
Mobile Bay supports important estuarine habitat—avoid disturbing shorebird nesting areas, pack out all trash, and never feed marine wildlife.
Sand Island Lighthouse and Fort Gaines mark Mobile Bay's strategic role in 19th-century shipping and Civil War defenses, while shell mounds testify to millennia of Indigenous coastal use.
