Great Hike!! Easy, except the first 2 miles are all Cow trodden but give the ankles a good work out! Great views of Mt Diablo.

It's a nice fire road trail, however, this time a year roads are trample by the cattle and rough to ride.
Place offers good climbing and downhill fun!!!

This is one of my favorite rides! Mostly uphill until you reach Wall Point Road then you get down hills reminiscent of a roller coaster ride until you level off at Stage Road. Once you reach Stage road you will cross pine creek several times before you cross back over the ridge and return to the tail head. I ride my bike to the trail head from my house using the Yngnacio Canal Trail by John Muir Medical Center and often ride back to the Yngnacio Canal Trail via Castle Rock Road. I do not recommend this ride if conditions are muddy or extremely hot.
