I went over to Georges Island the other year when Parks Canada had it opened for a weekend. It was very interesting, larger than it looks, and has a unique perspective on the Halifax waterfront.
They will need to cut back the brambles a bit, employ interpreters and have signs, put in washrooms and some facilities (like places to get something to drink, or perhaps eat). I got a terrible sunburn when I was on the island, because there weren't really any places to get out of the sun, and I got dehydrated too because of the absence of any canteens or vending machines.
