ssbn...
Fishing is great all up and down the West Coast of the Island. I was just in Kyuquot and it was great (just to the north of Esperanza)....reports from Nootka to the south are great (as is Tofino, Ukie, Bamfield), so I would imagine you should be fine being in the middle of Nootka and Kyuquot.
There is a thread on here somewhere I think that was updating reports from Esperanza specifically.
Regardless....fishing reports all up and down the coast are the best in years so you should be in for a good trip!
