I'm planning a visit to Volcanic Tablelands area near bishop. It looks like the roads are not paved. Do I need 4x4?
Not if you stay on Chalk Bluffs Road. It's unpaved, but usually in good shape. Just keep your speed down.
See more info about the area here. This focuses on climbing, but it's good for general info about the area, too: blm.gov/ca/…index.html
