There are three main roads across the Volcanic Tableland, all unpaved, and bumpy in places, but usually suitable for all vehicles including small to medium RVs. All three roads are accessed, in the southeast, from a paved side street (5 Bridges Road) off US 6, just 2 miles from the center of Bishop. All the Tableland is managed by the BLM, and no fees are due for access.
1. Fish Slough Road
A north-south route following close to several minor, seasonal drainages, towards the east side of the plateau, past three groups of petroglyphs all right next to the road, and with maintained trailheads - Fish Slough, Chidago Canyon and Red Canyon. Two other roads provide connections to US 6 in the east.
2. Chalk Bluff Road
An east-west route beside the Owens River at the foot of the steep, boulder-strewn slope marking the south edge of the tuff plateau, past the lower ends of Happy and Sad Boulders, and coming close to several of the more hidden petroglyph locations. After 6 miles it meets the paved road to Pleasant Valley Dam, near a large, riverside campground; US 395 is 1.5 miles south.
3. Casa Diablo Road
A diagonal route across the center of the plateau. The southern reaches are popular as free primitive camping locations, along little side tracks and on verges, while further north the road crosses increasingly remote terrain, eventually entering the wooded foothills of the Benton Range.
