No secret spots at Neah Bay and Sekiu that I know of for kayak fishing. Like SCARBOO said, the caves would be the likely place to go at Sekiu. It's super close and quite productive at times.

At Neah Bay, you'd want to paddle to the mouth of the bay and fish right by the Green Can. I think it's maybe a mile? maybe a little less. Fishing there is spotty right now... you may get into one, but you may fish a long time without. It's best right at first light and just before high slack. If you go a little ways out from Waadah Island then you'll get into coho thick, so stay in close if you want to conserve your bait.

Good luck and be safe out there.
