there's a gate. park in the neighborhood. it's a pretty walk and the ranch is easy to find if you follow the spray paint
Normally the fire road is for park rangers, fire patrol, and in some cases, the Boy Scouts. I would park down the the hill and walk, like everyone else.
Instead of going through the canyon there is gated fire road that will give a nice view from the ridge line. Make sure to park in the neighborhood.
You generally just walk it unless you have the keys
