Foresthill OHV/ China Wall etc comments

Anyone ride forest hill OHV? Rider planet says it’s limited to 50” trails but Im not sure about that.
Looking to ride on November 10/11 and need a good spot up north. Possibly hollister but it is south and I head north from the city to go home first, so it’s not ideal to double back.

Anyone have a recommendation to ride somewhere within 3 hours or so of Petaluma?

Everyone welcome to join to the ride of course! Will be doing a bit of geocaching as well on the ride.

If you can get away, check out https://www.fern45.com/. Its a great event!

I’ll also be heading to the Fern45 that weekend.
I do want to ride Robison Flats to a place called Big Trees, and explore some of the area out there; Foresthill pretty much single track for dirt bikes. If the weather holds maybe try and get up there Thanksgiving weekend.
