Mobile to do some seascape photography and let the kids swim. Can you recommend any locations?
Yup a HOTEL POOL. As of a 5 days ago all 21 Mississippi gulf beaches were closed due to toxic algae. Alabama beaches have been closed off and on all summer. As of a few days ago the algae bloom was still confined to Mississippi, but with the surge in temperatures that might change. Throughout the summer there's been numerous cases along the coast of a flesh eating bacteria contracted from the water. Several serious injuries and a few deaths, have been reported. I'd make sure to pay attention to the warnings, and not go in the water with any cuts, or skin breaks. As beaches go, I prefer Gulf Shores for it's clean white sand. Gulf Shores State Park, has a really nice beach area, and the mile long pier. We'll be going south next month, had intended on going to Gulf Shores, but with all the warnings, we may drift over to NO, and skip the beach till cold weather.
If you do go to Mobile, don't forget the USS Alabama and the museum. It is really something to see, and the kids will enjoy.
If you get closer to Pensacola, you need to go to NAS Pensacola. They have an outstanding museum there, lots of planes, and NAS is home to the Blue Angels. If they're in town they have practice days open to the public, parking, and admission to the bleachers, and the museum is free. Here's a link to NAS
https://www.navalaviationmuseum.org/attractions/blue-angels/ there's a schedule there. If you go to practice, there's a wide concrete apron between the hangers and the bleachers. The bleacher seating is kind of tight, hard to swing a long lens without hitting someone, so I stand on the concrete apron up next to the fence. Heads up warning, pay attention, one slipped in from the Gulf right over me, almost made me wet my pants. There are numerous really nice beaches between Gulf Shores and Pensacola.
