Fire road for most of the way until about the last mile or mile and a half. You will notice the peak off to the left of the trail by seeing a cluster of rocks that you haven't seen along the way. That day I went was pretty clear (12/26/2016) I was able to see Mt. Baldy & Catalina in the distance.
Lots of incline and great views. Bring plenty of water and snacks for energy. The start of the trail runs through the Lazy W ranch but they are pretty lenient on hikers going through there. Just be sure to call them and get their permission just to be safe.
