Staying local there should be enough to keep you busy for a while. I've pasted a few bits below - drop me a PM when you're over as I'm around there.

Cashen River exits the sea @ Ballybunion
The Northern side of the Cashen Estuary is reached by driving south past Ballybunion Golf Club and by passing the car park. Turn west on the beach and park your vehicle beside the dunes. There can be good surf fishing for bass when conditions are suitable, particularly on the extreme mouth of the estuary. The flooding tide and lugworm as bait are the best combination. Inside the estuary mouth and just below the car park, is excellent flounder fishing on the flooding tide with best results using crab bait.
Bait
Bait can be collected in the Cashen Estuary. This can be reached by following the road past Ballybunion Golf Club towards the estuary. A lane or small road leads to the northern shore at the old ferry crossing. Three hundred meters to the left and across a small field is a good location for peeler crab under the weedy banks in the muddy backwater. The thick mud here can be difficult to dig.
Beal & Littor - Beal Point is situated on the most north westerly tip of Co Kerry. The road down to the car park and the beach is on the western side of the point. The fishing is similar to Littor Strand with catches of dogfish, flounder and dab. Occasional bass can also be expected. The flood tide is the best time using lugworm and small white rag as bait.
