Nova Scotia in August

Anyone been/have any suggestions? Looking to plan for a family trip with our almost 3-year-old for a week. Would want to keep it to 3 bases at most, maybe 2.

Also considering Maine, though seems to be plenty of info on that. I am a little wary of crowds in August there, although maybe that’s only a problem in Bar Harbor? Since we only have a week I think we would fly even if we went to Maine.
