This is the newest trail at Leadmine and will push you to control limits. Knife Edge can be accessed from both directions off Arbutus Park. Traveling South to North will start on smooth single track into a few switchbacks then right into the ridge rock garden. Serious trials skills required to climb most likely 'hike a bike', for most. From North to South is more downhill option with again trials skills needed to descend. At the high point on this trail great views of the Hamant Brook are available to those brave enough to attempt.

Caution, primarily a hiking trail, double black difficulty for MTB

 reporter Trail is epic. I'd love to see an elite rider clean this. HAB about 33% of the way for me, but a beautiful trail and very much worth it.

 reporter In great shape ... but that doesn't make this trail (which prob should be a double-diamond) any easier. Was still cool to experience.
