The drive up isn’t bad at all - unmoded vans seen at sites seemed to manage it just fine. Any SUV will do just fine, likely most sedans as well. But the road is rutted so put some thought into your lines. Sites 1-4 easily accessible, don’t bother with 5-6 unless you have a a confident OHV. Take the left at the fork for the forest road for sites 7+. Bear spray + effective food storage heavily recommended by the forest service for this location.
