Lots to do on the penninsula in the summer, glass bottom boat tours, CheCheman ferry runs from the tub (Tobermory) to Manitoulin island. You can take your vehicle over and see the island. Tobermory is a great tourist spot with lots to see and do.
There is a great park nearby called Cyprus lake. It is run by the federal government. You can take the trail from the campground to the grotto, a natural hole in the stone shoreline famous with divers.
Red Bay, Pike Bay, Wiarton, Lions Head all great places to visit on the shoreline just a short drive to all.
Have a great time!
