Road 53 is unique. According to the Yolo County Surveyor, Road 53 has been a public right-of-way since 1889. The signs on the gate may be misleading. Yes, all the land is private, but it is a PUBLIC road. So you may hike it, or bike it. Stay on the 50-foot wide right-of-way! There are some tempting cattle trails along the creek bottom; don't do it! You'll put the use of this area in jeopardy!
The gate across the road (County Road 53) is the start of the trail. There is no place to park here. It is clearly marked and you'll get a ticket and probably a tow. See the Ride for parking details.
The gate crossings are annoying, but hang in there, it quickly gets very interesting. The narrow road is quickly enveloped by the canyon and surrounding trees. There is an old bridge at about the 2 mile mark, here is where the climbing starts. The grade kicks up and the switchbacks kick in. With good technique it is all very rideable and the views are fantastic. There is even a large, picturesque waterfall in the spring after good rains.
Spoil yourself by rolling on to where the public access ends at two big gates.
