South of the south jetty at the Columbia

Hi all!
Next weekend I’m heading up to Warrington for the weekend with the in laws to camp and fish for coho. If the fishing is slow I’d like to hit the ocean for bottom fish in that neighborhood. Looking at google earth it looks like there could possibly be a decent launch site rite at the south jetty. Is that a legal place to launch? Have any of you ever launched there? Is there a better place to launch near by?  I have a week to figure it out. Any advice or input would be awesome!

The best way I can describe that area is "gnarly". You do not want to try that area in a kayak. Crazy current, sand bars that extend way out, and submerged jetties. If conditions change at all from ideal you are in serious trouble.
