Just rode this trail today, very beautiful views when the climb starts, this trail is very long, not as short as you think it will take you, lot of dismounting needed but it’s not that overgrown, just really tiring

Tread is loose, but the trail is mostly clear. It’s hard to tell what’s solid and what’s soft on the edges. Definitely needs more traffic to pack down the loose dirt a bit, especially in spots that are a bit eroded. Fun but dicey

Both sections between West Fork and Valley Forge trail camps are a bit overgrown. Some PO especially closer to West Fork. A bit of poodle dog. A few gully crossings require dismount. No deadfall.
