There are 2 ways to fish Barclay Sound as a self guide with your own boat and camp.
1) Poett Nook - Port Alberni
Drive to Port Alberni, past toward China Creek, on to Poett Nook Marina and Campground. You will fish the south end of Barclay Sound and Bamfield areas, which will be great sockeye fishing, especially early in the summer. You can also launch in China Creek, or Port Alberni and run the hour to Poett Nook. The link above takes you to the marina website.
The commute to calm fishing zones is relatively short here: 3-10 miles from the marina is pretty good.
"Ukee" is great fishing all summer, but the camping is not so good. Surfer's Paradise is a bit of a drive, so every morning you have to drive to the dock. The daily commute to fishing grounds is okay. The 5 mile ledge and the 7 mile ledge off shore is where the action is. You fish off shore in the morning and return to the north end of Barclay Sound for the afternoon when it gets windy.
The road to Ukee is winding and rough on trailers and bearings, but it's a million percent better than Nootka.
If camping next to your boat is what you after, then Poett Nook is where I'd look first, especially if your boat is 21' or under.
