I highly recommend the Gaspe loop in Quebec and Cape Breton in Nova Scotia. Check AdvRider.com for ride reports, suggestions and photos. Think of riding mountain roads adjacent to the coast. They are not technical but offer enough curves and elevation changes to keep you entertained while surrounded by spectacular scenery. PEI is very scenic but the riding fun factor is nothing to write home about. I have only flown into/out of Newfoundland and can’t speak to the riding there. People throughout your areas of interest are very friendly. You shouldn’t have a problem finding people in Quebec that speak English in tourist areas and larger towns. You are planning on covering some serious distances. Ride safe and enjoy.
