I'll be the first to admit that I'm no expert, but this is a rough, rough ride. These are some of the oldest trails in the area and their condition is a testament to that fact.
The eastern loop in particular is in pretty bad shape. Massive trenches that used to be wheel ruts, slopes that have been washed out to sheer dropoffs more than a foot high, and snarls of roots covering the path in six foot stretches. The worst of this loop definitely comes after the early exit route that's available maybe halfway through the trail, but there's absolutely a broken wrist waiting for you on any part of it if you're not paying attention or your skills aren't up to snuff. Without some maintenance this trail might actually be better rated blue/black.
The northern loop isn't what you'd call pristine but what you can ride on (a section is blocked off) is definitely in better shape than it's eastern cousin. There's some pretty nasty transitions. I recall a heavy-duty rock garden right at the top of a hill that itself comes right after a switchback, but I'm comfortable saying that my issues with that came from my lack of expertise, not because the trail itself was a mess.
You like it raw? Give Renaissance a shot. Anyone who's not down for a fight or at least some bloody knuckles might want to check out Francis Beatty.
