A tidal pass is a funnel. Every cubic foot of water leaving Perdido Bay, Wolf Bay, Bay La Launch and the back bays on a falling tide has to get through one gap, and it moves fast enough that a competent adult swimmer cannot make headway against it.
That produces the classic accident on this coast: somebody swims near the mouth of the pass, gets taken sideways and then seaward, panics and tires. Do not swim in the pass. Not on either side of the bridge, not at slack water, not to reach the end of the rocks.
The east structure is a weir as well as a jetty, and its crest sits about six inches under the surface at mean low water. That means an apparently open stretch of green water between the beach and the visible rock is in fact rock. People run boats onto it every season, and waders walk off it.
Two more. The rocks are wet, sloped and covered in barnacles, and walking out along them in flip-flops is how the local emergency room fills up in July. And this is a working channel: charter boats leave before dawn, come back in the afternoon and are not looking for swimmers.
Check the flags at the access as you would anywhere on this coast. The double red closure is an ordinance offence in Orange Beach, not advice.
