Trip to Nova Scotia
Like Ray said boon docking is not common at all in NS. I would suggest provincial parks or federal park and both are accessible for online bookings. My favourite provincial parks are Rissers Beach and Graves Island both of which are located in scenic and historic spots. If going to Cape Breton I would suggest the provincial park at St. Peters as I would not tow to the federal park due to the steepness of the highway or travelling as far as Port Hood or Cheticamp and travel the Cabot Highway just in your vehicle. It's a spectacular drive. Fees at these park are all reasonable.
