We drove to the park from St. Catherines while on a break for the Shaw Festival. We got lost on the way looking for a stables where we can rent a horse for a day. There are planty of the stables aroung, none of them rent, though.
This is quite big and very interisting park with many trails and connected to (part of) the Bruce Trail. Park information on the Ontario Parks website can be found here
