The trail was apparently re-routed recently for the opening of Rancho San Vicente, and most older maps do not show the trail in the correct place (the old one still exists apparently, but it's marked "Keep off, under maintenance"). The track on this trail was verified and is up-to-date.
This trail is very remote and there's no cell coverage in the area. Make sure you have all the required tools and expertise to fix common bike problems (flat tires, etc).
Chisnantuk Peak Trail is a 2.5 mile "wide singletrack" connecting Calero County Park and Rancho Cañada del Oro. To get there, start at the Rancho San Vicente entrance and take either Lisa Killough Trail
or Cottle Trail
. Ride until these trails meet again at their southern ends. Continue on Cottle Trail
going west. During the wet season, there are three small streams that will need to be crossed (nothing big, really, and they should be dry most of the year). Cottle Trail
becomes a somewhat steep fire road on its last half mile. Ride it up to the Cottle Rest Site, where Chisnantuk Peak Trail starts.
Chisnantuk Peak Trail climbs from Calero to Rancho Cañada del Oro at a more or less constant grade of 5%. This grade is sufficient to keep a good pedaling stroke while gaining some elevation. There are nice photo opportunities three-quarters of the way up.
At the trail's end, you'll reach Bald Peaks Trail
(bordering Rancho Cañada del Oro OSP). At this point, you have the option of riding back down (2.5 flowy miles of gentle downhill, with fun and smiles!) or continue up on Bald Peaks and make your way down to the main parking lot of Rancho Cañada del Oro.
