Hi Emperor
I fished there approx 5 years ago. Was booked in at Gwe Gwe. There is a massive rock platform in front of Gwe Gwe. You will be fishing deep water - ideal for sliding. Slightly to the right of Gwe Gwe is a small bay - good place to target edibles.
To the north of Gwe Gwe is The Waterfall. You will be fishing in a deep channel / mouth. Good for edibles
From the Waterfall you can walk southwards, there are a number of little gulleys to target edibles.
To the South of Gwe Gwe, is the Msikhaba Island which i am sure you might have heard / read of. I personally have not fished Msikhaba island.
The bait most suitable for edibles will be crayfish, pink prawn, cracker, chokker, sardine, mussels. Hook size will depend on what you will be targeting. I found that a 2/0 - 3/0 worked best. Target species now will be copper bream, brusher and galjoen if you are lucky.
Please carry a lot of sinkers. I lost a lot of sinkers at Mkhambati due to the rocky terrain. Try the pulley rig, I think it will work wonders.
Hope this helps
