Head south down hwy 101, then west thru Fort Hunter Ligget, up to Plaskett Ridge (Nf route above hwy 1 and coast, coooool), come out at Gorda and south into Cambria.

Make way east to hwy 58 at Santa Margarita, travel east to Soda Lake National Preserve, ( remote and has some side roads that are great, and camping ), check out Painted Rock, and enjoy the solitude.

Keep east to hwy 166, cross, hit Cerro Noereste Rd., east to Quatal Cyn, very cool things to see here (and camping), down to hwy 33.

Then, and you have a choice here;

a. North on hwy 33, cross to Cuyama and head up to Cuyama Lookout ( Old , neat, and way up there, some hiking as well in the area.)

Or;

b. South on hwy 33 to Lockwood Cyn. Rd. then east. ( Camping and lots of cool sidings on this route).

Either way continue east into Lockwood, and this will eventually take you to Gorman OHV, where you will certainly find something to do there with your rig

That pops you out on the Grapevine and Hwy 5 ,you can find your way home from there...
