Wally-o hit it on the head, be sure to visit Cape Breton Island, on the Eastern end of Nova Scotia. I live in New Brunswick, which you would be passing through on the way... I would heartily recommend (if time allows) to cross the Confederation Bridge from Bayfield NB to Borden, Prince Edward Island -- it will take you to one of the most picturesque areas in Canada, and then you can cross over into Nova Scotia from the other end of PEI, taking a 1.5 hour ferry ride across.

Feel free to contact me at bcormier@hotpop.com for any info on the area, I love helping people discover this part of the country!

Brian.
