My wife and I paddle together in sea kayaks. We have paddled at Meaher State Park several times. We usually put in beside the fishing pier. From the pier going south takes you into the open bay. We usually go to the left (east) and paddle under the bridge through the lagoon to a river.
The main attraction of this site is the alligators. We always see several in the 4-6' range. There is supposed to be a large one that hangs around but we've never seen him. There are always birds around mostly waders. There are usually some fishermen. Depending upon the wind it can be very flat or choppy. You can paddler up the river and under the highway 90 bridge near Spanish Fort.
We were resting on the river and my wife said, "I can relax now that there aren't any gators" I then pointed out several heads near where the water gets deeper. We haven't explored more than a few miles of the river near the park.

$2.00 to get into the park. The boat ramp is free (I think).
From Mobile take 90 east to Meaher state park. The park is on the right. There is a boat ramp but we usually put in near the fishing pier. If you get to Spanish Fort you've gone too far.
