This park has several entry points from the surrounding towns. Plenty of bootlegged single track that doesn't appear on the park's maps. I've ridden this place for almost 20 yrs....and am very discreet about when to poach...as there is some sweet off limits trails. Weeknights late and very early AM weekdays and weekends will give the window to play in the no bikes allowed spaces.
Plenty of climbing..rarely get out of there w/o 2500-3000ft of climbing over 12-15 miles. Some descents will get you into the 40mph + realm. Be courteous to the Horseback riders and the hikers and all will be fine. Tick one off and the ranger will be waiting for you.
Single Track Trails you can ride legally. Blue Oak descent..has plenty of single with some airborne options, West end descent of Crest Trail down to the Bear Creek staging area. Alhambra Creek single track is bootlegged and not maintained by the park..is a blast, but be aware of others as you;ll carry speed into blind turns.
When rain hits...it goes from cake mix to all out clay sludge and will become impassable in Winter. Summer is dry HOT and dusty. Bring plenty of agua.* Review edited 5/27/2009
