From the top, at the intersection with Rose Hills Fire Rd
, the trail is mostly flat until the intersection with Tank Fire Rd
. Stay left, and the road begins a slow descent, curving widely around a few hillsides. After a crumbling asphalt section, a fun singletrack, A-Line
, splits to the right. At this point, Peppergrass climbs and descends a series of steep hills, soon cutting across A-Line
again, then ending at a small parking lot on Greenleaf St, next to a large, concrete-covered reservoir.
Starting from the lower end at the reservoir, the climb is really steep. It's a popular way to start Turnbull for those who love to climb. Personally, I took one look at it years ago and vowed to never try, but my guess is somewhere between 15-20% grade.
