40 years as a diver and I've never even heard of this place. Sounds awesome.
The North Coast (north if San Francisco) is not really a place that the average diver would go. In other words, it’s not really a dive vacation spot, unless your were an abalone diver then it was considered a mecca. But abalone has been closed now for 6 years and an entire industry went away with it, including one of our most beloved dive shops Sub Surface Progression.
However, the scuba diving can be really fantastic if you know where to go. It’s wall country for sure with pinnacles, spires, canyons, huge rock formations, crevices, swim throughs, etc. Most people that scuba dive up there are hunting. The game and sea life is abundant with big lingcod, a large variety of rockfish, scallops, crabs, and of course urchins, lots of urchins. The place would be what I call a real adventurers paradise. People who dive here need to have some experience in cold water, seasoned vets that can handle a lot of gear, thick suits (or drysuits) a healthy ocean. It’s not for the faint of heart or someone who just got certified in the warm calm waters of the tropics. I have to be honest.
There are no boat charters now, there used to be a long time ago but diving is very seasonal and dive tourism is not enough to sustain a venture.
I had a boat from 2000 to 2010 and mapped a lot of the area. There is a stretch between Albion and Little River (Vandamme) that is about the best pinnacle sheer wall country that I’ve found up in that area. There are also some pretty impressive sheer walls with undercuts just south of Albion too.
That whole stretch of coastline, about 60 miles, is a real gem. The problem is it’s isolated, there are no dive services (shops) so we have to bring everything including all our tanks, it’s cold and it can get rough. But when it’s nice it’s really nice.
I had an old friend just come up from LA and he brought a first timer up with him to the big bad “forbidden” north. The dude was blown away with the diving. He said they have nothing like it in Southern California.
A lot of us use kayaks but an inflatable would be great to have. That would get you to any of the best offshore diving. There is plenty of great shore diving too. I know people who use scooters to get out to some of the fringing reefs and walls from shore.
