Green section is rough road, not super well graded, but certainly doable in almost anything. No water bars, only slight overgrowth (brushing against some leaves, no damage should occur)

Yellow is super overgrown. Some large holes, no real big water bars, but medium clearance obstacles for sure. Biggest thing is overgrowth, it starts out not bad, but quickly gets thick, like, vehicular bushwhacking thick. You can get through, and we did, but expect serious pinstriping. Not just brushing against stuff, but thick branches. It isn't continuous, but it does fluctuate for the entire length, and parking spots/pulloffs are sparse

There are a couple downed boulders, but they can be bypassed, both my SUV and a pickup that came later were able to do so

We parked a bit past the 12km mark, as progress was slow, and we were close enough that it didn't matter, but it never got worse than what w'd already been through, and wasn't thick continuously after that either. you could go to the end

Road is rough but passable to subarus up to Zum Peak rec site but is growing in with mandatory pin stripes up to Zum Peak rec site, extreme pin stripes after that and need high clearance unless you want to leave parts of your exhaust behind like we saw a Rav4 doing.
