We just decided to drive our 22' sprinter camper to Nova Scotia after the 4th. We'll spend a week checking out Cape Breton, the Bay of Fundy and if we can fit it in, Prince Edward Island.
The absolute one must-do thing in NS is to find a restaurant in Digby where you can get scallops right off the boat.
The northernmost parts of the Cabot highway are beautiful. And oh so close to a 200 ft drop into the ocean.
Also, keep in mind that outside of Halifax, pretty much the whole province shuts down after 8pm.
Banff for 3 days, Glacier NP for 2 days and Yellowstone for 3 days in early to mid-August. Do I need to bring bear spray, anyone?
There's a beautiful golf course next to the Fairmont. The day wife and I played, there was a bear walking across the green we were shooting at. We held up play for a bit.
Sounds corny, but if the Stampede is still going on when you're there, it's a goof and definitely worth going for a day. The chuckwagon races are the Canadian version of Ben-Hur.
As for myself, wife and I have no plans this year. I'm probably facing a knee replacement this fall and get pretty sore if I walk a lot, so not much point in travel.
