In response to the requests for additional info regarding touring in Nova Scotia:

I toured there about 15 years ago. What I recall is that I really enjoyed Cape Breton Island, not just the Cabot Trail and the national park, but also the area around Bras d'Or lake.

I was disappointed with the Annapolis Valley region, though wet weather there didn't help matters. I also had mixed feelings about the south coast between Halifax (a pleasant city) & Yarmouth. The roads along the coves are lovely, but the main road has far too much traffic to be enjoyable. The problem is that at a minimum, you must take the main road to get from cove to cove. The area north of Yarmouth was OK, but nothing special, I thought. If you're lucky, you'll get to see water seemingly flow up creeks when the enormous tide comes in. At some point, I biked across the mostly empty interior from Annapolis Valley to Halifax. It was interesting simply because the landscape was quite different from everywhere else I had been.

All in all, I wish I had spent more time biking on Cape Breton Island, and less time on the mainland.

This past September I was biking on Prince Edward Island and the Iles de la Madeleine (Quebec) in the middle of the Gulf of St. Lawrence (and accessible by 5 hour ferry from Souris, PEI). Biking was challenging on the Madeleines because of the constant strong winds, but the islands are absolutely lovely and very much worth visiting. PEI had better biking, if only because of the weaker winds, but simply wasn't as interesting as the Madeleines, we thought. Still a nice place to visit, though.
