Deer Island is on Biloxi Bay and is easily accessed from Davis Bayou of the Gulf Islands National Seashore. The island is five miles long and a quarter mile wide. A long sandy beach backed by pine forest and palmetto is very scenic and privately owned. As you circumnavigate the island, the water right off the shore is very shallow, allowing a closer, more peaceful look at the island and some distance from motor boats. At low tide sand flats arise. Dolphins are often seen around the offshore side. On the return trip the views are dominated by the urbanized coast as casino hotels line the shore.
