Grade 4 in the dry, Grade 5 in the wet
Steep drop-in at the top looks worse than it is (unless it's wet!!), the rest of the trail is mostly steep-but-flowy with a couple of more technical rutted sections. Pretty easy in the dry, slippery and challenging in the wet.

Apart from the first steep feature, it's a fairly standard , easy grade 4 unless wet due to continuous slope.
