Some good advice already posted.
The road from Port (home) to Bamfield is one of the worst the Island has to offer in terms of towing a boat. I've destroyed
TWO trailers doing just that, had to leave the boat in the ditch

once and returned with a replacement trailer to find it thankfully intact. Take an extra spare tire and
DO cover the engine canppy and water intakes with plastic/duct tape! Go SLOW, Headlights on at all times, and hope it's not too busy, or the dust plume makes it nearly impossible to see. Now, I just run the boat down from Port, and will likely never trailer that "
road" again.
For fishing: Most troll. Bait, spoons and hootchies. A few motor-mootch, but the action is often faster on the drag. As soon as you catch a keeper, clean it to see just what the menu of the day is, and gear up to match the hatch. Repeating the Magician's advice, GET OUT THERE EARLY! The best bite is right as the day begins to lighten - always. Places for springs - The Wall, Swale Rock, Diplock, Pill Point and off of Beale. For coho, surf line off Beale and just inside (had MANY tremendous days there - up to 100 released over an afternoon - Watch for frantic surfacing bait-balls, then break out the fly-rods or light jigging sticks. Don't be too suprized when you nail a spring down ten or so feet in that mix

) Bone-jarring hook-ups that you actually get to witness about 1/2 the time! Sweet!
Poet Nook is a nice quiet and freindly place, well situated to launch quickly onto the fishing activity. There are a few nearby lakes, but most are not all that conducive to swimming. There are two right beside the road to Nitinat, one even has a sorta beach, likely your best bet for the kiddies. A few trout in both, so worthwhile to drag along a rod. Get a copy of the Backroads Book, it will come in right handy.
Your timing will be great, should be loads of fish to keep those arms tired!!
Enjoy!
