Fort Ord National Monument trails are closed from 30 minutes after sunset to 30 minutes before sunrise.
This is a fun downhill trail that is ridden in reverse for the Sea Otter Cross County course.
Here is the "reverse" description:
On the climb you start up through the Oaks and have some fairly steep turns to climb through. Hold on as the climb levels out a bit and gives you a break before a second steep section that leaves the Oaks and takes you up the ridge into the Manzanita.
After a final steep climb that turns gentle at the intersection with trail 85 you will end up on a gradual downhill that dumps you into Pilarcitos Ridge Rd. A lot more fun as a flowing Downhill which is how it is typically ridden.
