I love the "Broken Group" and am little familiar with that area!
But, it has been a few years, since I have been that far in... and does Toquart now have gas? That would be a good thing to know!
I second the, “Make sure you have some charts or gps” super nice area and easy to forget about the “ROCKS”! Personally if I was leaving the marina going to Lyall Point (to catch a fish), I would head for the south end of Hermit (between 135-145 degrees mag). Southend of Hermit, cut straight to the “red” light/beacon - that area is clear. But hey, what do I know… the last “rock” I hit was putt’n around in the Broken Group Islands. There are shallow spots and rocks all over the area, and "all" rocks are not charted!
Crabbing and prawning… depends on the commercials… usually can find enough, at least for me!
Mudslide, if you want something that is more sheltered waters than outside of Port Renfrew - you will love it there! Are you talking camping with a trailer or tent? If tent - about anywhere in the Broken Group is good and have beach access by boat. Just find a nice little cove and start exploring!
