well could you point me in the direction of some specifics
?
Try the inlet on the north end, or the causeways on the two roads going in.
I can't get more specific than what I posted. There is public access to the water on Pawley's Island. The inlet of the south end is not real conducive to fly fishing, unless you're an experienced surf fisher. Then you might have a chance if the fish are in close.
The inlet on the north end has a bulkhead along the north end. That's your best bet for flies if you hit the tide correctly. You can wade some there, but that too would depend on the tide. A sinking line is a good choice.
There's two roads that provide access to the island. Both cross over creeks. At those causeways you can access the creeks, but you may have to wade to get to the water for casting flies. Watch out for snakes!
There are grass flats on the back side of the island, and it's possible to find fish on those flats when the tide is correct. You're going to have to walk/wade thru mud & sand to get to those places. Waders might be good unless you want to wet wade.
That's the best I can do with being specific. You have to figure out the best places on your own once you see the conditions. Not every place will hold fish, again depending on the tide.
Watch where you park, the Island Police are not lenient about parking. Otherwise, they're pretty cool.
BTW, it's not anything like trout fishing in a stream.
