Fripp fishing
I re-read your question and realized I answered for the wrong Island! Been many years since I fished Fripp Inlet...after you cross under the Fripp bridge going out of the inlet, on the right there used to be a Cross in a yard...there was a flat there where you could catch flounder and sometimes redfish. From the Fripp Island marina, as you go out toward the bridge, there is a creek on the right within sight of the marina. Go into the creek until you get to a sandy bluff, in a turn, on your right. Fish the grass line just before the bluff on an incoming tide for trout and redfish. You can also fish on up in this creek at high tide for redfish...
Going out of the inlet, there is a wreck 1 mile off the coast...I have not been there since I've gotten a GPS, but it is on the charts. I've caught nice big redfish here. There is a bouy off the inlet, 6HI I believe it is (maybe 6 miles offshore?), where you can catch spanish and kings...
Going out of the Harbor Island inlet, after you go under the bridge, you can see a creek on your left. You can't get across the flat to this creek from 2 hours before low til 2 hours after low...we used to go in before low and wait on the fish. Fish about 50 yards up in the creek, anchoring on the right and fishing the grass on the left.
One last place, south of Fripp Island is Pritchard's Inlet and Pritchard's Island. Have caught large redfish in the inlet. We have also made a day trip of it and anchored the boats in the inlet so we could surf fish the incoming tide. When the redfish are there, this is awesome.
Again, hope you have a great time and catch alot of fish!!
