I second the other poster's comment.
You increase your chance of seeing orcas if you drive up to Telegraph Cove (a cute little village) and get an outfitter there to go out with you.
Still no guarantee though. We didn't see any up close, though saw some splashes that's probably made by orcas. Bottom line, a nice paddle and only a CHANCE to see orcas.
