Dauphin Island is a quiet barrier island in the Gulf of Mexico, just off the coast south of Mobile. It is a low-key alternative to the busier beaches at Gulf Shores, and one of the best birding destinations in the country.
The island is home to Fort Gaines, a Civil War-era fort that guarded the mouth of Mobile Bay during the famous Battle of Mobile Bay in 1864. The fort is open to the public and well preserved. A ferry connects Dauphin Island to Fort Morgan on the opposite shore. The Dauphin Island Sea Lab Estuarium, a public aquarium, features marine life from the Gulf and the Mobile Bay estuary.
Every spring, Dauphin Island hosts one of the most spectacular bird migrations on the continent. Exhausted songbirds arriving from across the Gulf of Mexico make the island their first landfall, and more than 345 species have been recorded here. The Audubon Sanctuary's 164 acres of maritime pine forest, freshwater lake, and observation boardwalk are the prime birding spots.
The island has a handful of casual restaurants — The Oar House and Barnacle Bill's are the standouts — plus a couple of gift shops and enough rental accommodation to make a quiet beach weekend easy to arrange.
