Sooo someone recommended this adventure years back when I was visiting Vancouver:

Widgeon Falls/Lake in Pinecone Burke Provincial Park. You rent a canoe/kayak early in the morning and paddle down Widgeon Creek about an hour to the trailhead. Then you camp around there and can hike to the falls or the lake. The lake seems like a pretty far walk, so we weren’t able to make it all the way, but the falls are beautiful.

Really solid adventure overall.
