Wasn't paying attention and took a wrong turn up this road in my Pilot. It's in ok condition to 1 km. Took a left at the dotted line until first switchback. It got narrower and steeper. Decided not to risk it in case below report was true. Plenty of space to turn around just before switchback. Also maybe 1 or 2 spots along the way you can turn around easily.

Road is in good condition, and there's a big parking area around 0.60km. Road after that gets steep, rocky and eventually degraded where only ATV can drive.
