Wiarton (CYVV) is about 30 miles north of Wingham, easy to find (VORTAC on the field). Nothing at the airport but there are 3 courtesy bikes in good condition that will get you into th town 4 miles away. Tobermory's just another 15 miles to the northwest in some pretty spectacular country but I don't think they have anything near the field. If you're really amitious check out Gore Bay (CYZE), courtesy car & bikes at the airport. You'll need a high ceiling to get there in a single because the shortest route involves a 16-mile water crossing- a 172 will glide to shore from approx. 5500' ASL. Closer to civilization London and Waterloo both have good restaurants at the airport.
