The Cabot trail is a Canadian legend in the motorcycle community. This loop through Cape Breton Highlands national park rises and drops from the coastal shore to the mountain tops and back to the shore again. Watch out for moose, and be sure your clutch is in good condition because the mountain switchback descents can really take their toll. Start at Baddeck and take a counter clockwise route for the best views. Also resist the urge to finish out the loop by switching onto the Coastal trail through inverness back to Main Land Nova Scotia. The coast isn't visible on that branch,and its just slow country roads, stick to the Cabot Trail through the whole route back to Baddeck, and take the Trans Canada back to the mainland.
This route includes the aptly named hamlet of Sweets Corner. Lots of nice curves and you can make a loop of it by taking the 215 back up from Newport Corner to Brooklyn.
This one is a bit of a mixed bag - something for everyone. Beginning on the Gaspereau River Rd its a nice cruise. If you can manage not to get lost, head up Deep Hollow Rd, which features some super tight hairpins, albeit without the best road surface. Cutting through the quaint towns around Wolfvill (a beautiful town itself) heading up the 358 will lead to some twisties and up the hill to a spectacular lookoff with amazing views of the Minas Basin and surrounding country.
On my map/logbook this is rightly described as the BEST ROAD EVER, BY FAR. If you like tight, fast twisties with beautiful scenery and minimal traffic, well, of course you do, and this is THE place for it. That being said, the eastern part of the 332 towards Lunenburg has some pretty sketchy/bumpy/broken pavement. It's best avoided. If you're in the area, head to Bridgewater and then go down the 322 to the ferry and back up. You're gonna want to do this one at least twice anyways.
Hwy 212 is great for a good afternoon blast. Some nice corners near the airport give way to a good mix of straights and sweepers. Moving on to the 357 at Elderbank tightens things up slightly and there are some nice views as you follow the Musquodoboit River. Just be sure to keep within the speed limit as there's a Cop Shop in Musquodoboit Harbour.
