Frank, you’re in one of BC’s best areas. It won’t take long to figure it out either. Dry fly fishing is my all time favorite, especially when the ants, hoppers and big caddis hit the water. Your local shop will point you in the right direction and then it’s just time to become proficient. As with all catch and release, etiquette is key. Playing(not too long), netting(with a proper soft touch or rubber net) and not allowing fish to bash on the rocks are a big part of river/stream fishing. Pack a gun with you as there are lots of griz in that area too. Good luck.
