Depending on the size of your Class C, you might enjoy a side trip to Meat
Cove off the Cabot Trail. It is not suitable for larges rigs though. Also while on Cape Breton go to the Alexander Graham Bell museum in Baddeck.
We enjoy hiking and there are some great trails on C.B. - some short and longer options available. We drove our truck camper around the trail and spent several days doing it. There are lots of stops to make and things to enjoy if you have the time. There were several c.g. in the National Park, some with hookups, others not much more than a parking area - great drive!
