Solstice comes down Loma Alta, ending at San Domenico School. Since Loma Alta is in the middle of a large chunk of Open Space bordered by several towns, you can ride up Loma Alta from Fairfax, Sleepy Hollow, Terra Linda or Lucas Valley (via Big Rock). Once at the top, look for the opening in the fence trail that drops down the East side of the mountain. If riding up from Fairfax on the fire road, there's an alternate singletrack route off to the right before you get to the top.

It's a short, but wild ride. Not for noobs.

Always respect private property.
