[QUOTE=getten old]i am leaving for kauai this week. The family is going for a month!!
can anyone tell me about fishing from shore?
Well, there are worse thing, I suppose, than a month on Kauai. Mostly what BDowning said. Good flyfishing on all the islands is either very limited, or very secretive, or both. There is a wade, sight-casting bonefishery on Oahu, and guides to take you out. There are trevally from little blue spottted to giant blacks available everywhere on all islands, but they are scarce and fished very hard. I have watched locals catch bonefish on bait from the rocks just east of Brenneke's Beach in Poipu. The sandbar the bones were holding over was not reachable with a flyrod from shore.
There is a peacock bass fishery (accessible only with a guide) in the (only large) private reservoir near Koloa, and a laughable, planted, poke thru the undergrowth trout fishery way up on the plateau west of Mt. Waialele. There is a promising wadeable reef east of the Hyatt Regency in Poipu. See my website about that area.

Unless I am going to Oahu, I have stopped bringing my rod to Hawaii
