Starts on the Howe Sound Crest Trail, branches off perpendicular to the main path right between the two wooden foot bridges and goes up the Christmas Gully to the Strachan peaks. From there runs southeast to Hollyburn, then descends down and west on the Baden-Powell trail.
Note: Do this hike clockwise. Give yourself 5.5-6 hours just in case. Experienced hikers.
The BCMC winds up grouse mountain, adjacent to the Grouse Grind but through sections of less maintained trail sections and with much less (but bi-directional) hiker traffic.
I rode this clockwise. There is a gate that big bikes can go around just past the first hump on the track.
