I've mentioned before that the Cape Chignecto Coastal Trail is my favorite hike on mainland Nova Scotia but a close second is definitely the Kenomee Canyon loop.

At around 20km, the Kenomee Canyon loop trail is definitely doable in 1 day but I’m in for the camping so I’ve always done it over 2 days with a night of camping in between.  I love the feeling of remoteness you get at Kenomee by which I mean that you won't meet many (if any) people.

It also has a lot of variety in the type of terrain and forest that you trek through. There are also a couple of brook crossings thrown in as well, one of which usually needs to be done barefoot.
