I have waded Wakulla Beach, but only from the parking area as far back as the dyke.
Out front it's reasonably firm bottom with some rocky areas.
Get around the point where the long bar is that captkeyser mentions and it becomes muddy and difficult, but not impassibly so. A walking stick about as tall as your shoulder is helpful. Wade fishing the east bank of the creek is worth the trouble.
As you head north up the east bank you will come to a small, bare oyster bar, then a slightly longer grass covered oyster bar. Fish both these bars from the bank before wading out on them. I have caught nice trout and reds on both these bars between the marsh and the bar. I have also caught nice fish casting from the outer ends of these bars.
As you continue on around, you will come to a sandy point. Much easier walking here. If you are standing on the point facing west there will be three oyster bars and a sandbar on your left. It's deeper between you and these bars, shallow around the bars. It's also deep in front of you and to your right almost all the way up to where the creek curves to the left. You can access this point without having to go all the way around, by the trail that cuts through the marsh. From the parking area skirt the west end of the woods around to the right and you should be able to see the trail on your left when you come to it.
Continuing on up the creek, the natural channel on your left becomes shallower developing into a small, sandy flat area. The edge of the marsh angles away from the channel and the wading becomes muddy again. If I see 'gators, they're usually from here on up. They don't like to be stepped on, even though they are firmer footing than the muddy bottom they tend to move around a lot.
As the creek curves to your left, a long, deeper hole starts here. There will be two oyster bars on your left. Don't throw a castnet here unless it's a net you really don't like, or you just want to practice diving a castnet up out of a rocky hole. Beyond this you will come to a section where you will be back up in the marsh, the hole is a vertical drop off from the bank. Beyond here a bag with 5 trout and a redfish in it gets pretty dang heavy before you get back to the car.
Moving on up from here it gets sandy again. A little deeper toward the bank, shallow sand, then the upper end of this hole which peters out into shallow sand shortly.
Following this sandy area it gets muddy again and the bank curves back to the right. There is a relatively large oyster bar, or a clump of small bars depending on how you look at it, on the left. All along this stretch between you and the dyke is a deeper hole. On foot, I've never been further up than this.
Carry drinking water with you. Walking this can be considered a workout for the day.
Watch for stingrays. There's a bunch of them in this creek and they don't like to be stepped on any more than the 'gators.
A walking stick will give you something to probe ahead with and move the critters out of your way in water too murky and deep to see the bottom.
