I'm not sure if it is time yet, but Hospital Hole (for pay access) is a decent spot for access to tidewater on the Trask river. It can get pretty crowded when the fish are thick, but my experience is that people are able to fish in sync without too much tangling.
Hospital Hole is off ??? road, just past the Tillmook hospital. There is a barn on the side of the road with a sign (or was it writing on the barn?) for the location.
You can also fish from the Jetty at Barview park. Nice area but be prepared to loose tackle on the rocks.
EDIT: After making this post I realized HH was not off HW101. I don't recall the name of the road, but if you follow the signs for the hostpital then continue past the hospital you we be there.
To get to Hospital Hole, go west out of Tillamook towards Netarts, or the Three Capes Loop. When you pass the hospital, you'll see a bridge that goes over the Trask River. Just before the bridge, turn right onto a farmer's property. There is a shack there. It costs I think $4.00 to trespass on his property. Drive onto the property until you get to the crowd fishing. Best time to fish is low slack tide into the incoming tide, and second best is right before high slack tide until the tide starts back out. Of course, there are exceptions to the best times.
I lost my biggest salmon of my life there about 1991. I hooked one on a bobber, and played it for probably 30 or more minutes. I never saw it, and it was very heavy, and would occaisionally do the head shake thing, and run out, and I'd bring it back. Well, there is this snag in there called the "Alligator". It headed for that snag, and I couldn't get it to not head that direction, and snap goes my line. Just before I hooked that fish, another guy landed a 53 pound chinook right next to me. His fought the same, and took him forever to land it. However, his fish didn't go to the "Alligator".
I never saw that fish, but I've not played one quite like that since.
Although I have not done this, and don't quite know where they do this, but I've heard that you can cast spinners from Highway 101 north of Tillamook and south of Garibaldi into Tillamook Bay somewhere by the Ghost Hole. I've got a friend that landed one there casting spinners a few years back. If you see a bunch of boats trolling in the east side of T-Bay just south of Garibaldi, you are at that spot. I'm not sure where exactly that spot is, but I'm sure you won't be alone.
Good luck, and let us know how you do. Too bad we have to sit at a computer and can't fish today. I've not been able to go for a week and a half, and I can't go for a few days yet to come.
