You just drive highway 30 through astoria, cross the bridge turn right in warrenton at the first light. drive through warenton until you reach hammond, you will see signs telling you the public launch is on your right.. launch your boat, go out the jetty turn left drive 50 yrds and look for the 20 ft edge on your sounder and bang crabcakes for dinner! if you have a small boat you can limit 50 yrds from the launch... The smaller the tide the farther towards the mouth you should go... and of course the 3 hrs before and up to high slack is best, it can actually make all the differnce, I also go further out if there has been any real heavy rain in the last 24 hrs. Have fun
