Please help with recommendations for eastern Canada/Cabot Trail.
 

My family (including 2 boys, ages 5 and 8) are heading east from Ontario next week. We'll be stopping at Riviere du Loup for a night, Halifax for two nights (over the weekend), then we'll be in Baddeck/Keltic Lodge and on the Cabot trail for 5 nights then heading back.

Can you please recommend 'must dos' in any of the areas that we'll be? Something cool or neat or something not to be missed. I'd appreciate any suggestions!

Thank you!
Danielle, Joe, Jacob and Isaac.
