Upon entry to Bone Shaker you may ponder, "Hey, this ain't all that". Enjoy that thought.
Gradually the trail becomes rougher and then downright difficult. The combination of many of small to medium drops and extremely rocky terrain will literally shake you to the bone. The further you go, the steeper and looser it gets.
This trail is not for beginner to intermediate riders. Do not attempt, or encourage others to attempt, if the skills aren't there.
