Mouth of the Waukwaas can be good now. Rupert Arm will have coho jumping, but they rarely bite. Can drive a person nuts!!
If you take the road (Hwy 30) to Port Alice, you will cross the Waukwaas twice as it splits just downstream on the highway. At the first crossing, there is a pull out, park there and you will find a trail that will take you downstream until you get to the canyon. Some good pools to fish on the way down. You can also access the river via the many cut blocks off the West Main, which you will find after the first bridge. Turn right onto the West Main and go explore.
Good luck
Cheers
