I used to, but more for money than for enjoyment.  Before I owned my canoe a trip would be $30/day for canoe rental.

While nowhere near BW/Q, Frontenac PP is well set for hiking.  A nice network of trails, well maintained.  The campsites are not as private as one might like, but understandable considering the traffic the park gets.

These days I think of hiking as an all day portage with fishing spots I can see but not get to.   :D
