Also did the trail in 2019, but drove there, too far to ride with kids in tow. The biggest issue we had was the mosquitoes were incredibly plentiful around dusk on the trail. Didn't do much raining while we were there and 35c tires were adequate for everywhere we went. The small gravel was a bit deep in a couple spots but few and far between. As someone else mentioned, the campgrounds along the trail on the north were well packed with little privacy. Off the trail the roads were fairly hilly, nothing big or too difficult, just nothing flat in a lot of places. We stayed at the Lord Selkirk campground, in the 5 miles from the trail to the campground there wasn't more than 20 level feet it seemed, they also have a scottish museum at the campground that was a nice diversion. The singing sands beach on the NE was also fun if you take the time to relax, in the walk from the parking lot to the beach you cross a bridge that says not to jump off of, the lifeguards who are watching didn't care that everyone was doing so and the current coming in would sweep you fast into the inlet making for an exhilerating jump. Overall the island was a pleasant area with nice lighthouses, and beautiful beaches.
