Do a search of these and "OHV" Stonyford, Foresthill, Georgetown, Mendocino, Penny Pines, Downieville
all within 2-3 hours (or less) of Sacramento.
Also some great street riding: in the Delta, foothills, wine country etc.
As far as riding in/near Sacramento? almost none except for the Delta area (street) and one basic, small OHV park (Prairie City in Folsom).
My buddy Mark puts these paid (reasonable fee) rides on.
Good way to get to know the areas. He knows Norcal really well. Lots of dual sport stuff.
