Generally, if you stay between the channel markers, you're good. There are a couple of spots getting into sloughs and such that are iffy. I'll see if I can come up with a basic map for you. I'll give you a little tip. This is a SECRET. If you're looking for clean water for surfing, and minimal traffic. Come out of paradise point and go left, up river. Don't tell anyone else, because we like it this way, but EVERYONE goes right, so there's nobody up river. Once you get towards the steam plant, there's a long section with minimal housing/docks. You can roll that monster wave wherever you want with no worries. But that's a SECRET!
If you're looking for people, parties, and boats to tie up with, then down river is the direction to travel.
