Never found the trailhead. Here is what we did find:
- Instructions in the 2008 edition of "103 Hikes" don't work. They have you turning right at the logging road and I'm pretty sure you should turn left.
- The first option described in http://www.livetrails.com/trail/12/Cerise_Creek was a clearly flagged trail at least up to and onto the logging road.
- If you turn left onto the logging road and walk a few hundred metres, there is a bit of a clearing that we mistook for the fork at which you're supposed to turn right. Somewhere in the clearing there is one piece of pink flagging tape. After unsuccessfully trying to find more, we turned back and discovered that the abundant flagging along the logging road continued further on.
- Found this set of instructions after getting home, and it looks good: http://www.clubtread.com/sforum/topic.asp?TOPIC_ID=31433
For various reasons, we decided this hike wasn't in the cards for today. Might try again in the fall or winter.
