The East side of Boyette has more challenging trails, yet not quit as much so as Alafia. But you still need to have your skills up for some of them.
The Abyss is almost two miles of technical drops and climbs - weight back, easy on that front brake!
The newest trail just South of Abyss is Imp Gulch - it has easier/harder options and the easier is complete with some of the harder options still in need of being finished.
NorthWest, Southwest, Northeast, Southeast is what we call the Quadrant Trails has all the switchbacks you would ever want. There's about 8 or 10 miles worth.
