BLM camping near St. George

We'll be passing through the St. George area in a couple weeks and I'm hoping someone might have some suggestions for good, dispersed (free) camping in the area. The St. George page here on MP mentions camping on BLM land and I'm sure we'll find it but perhaps someone knows of a great spot?
Thanks!

not sure if its too late, but there is some free camping at the base of Green Valley Gap.
Get on Dixie Drive, and make a right up Canyon View Rd. At the start of this road, there will be a sign for the Green Valley Spa. The spa will be on your left, along with palm trees. Contiue down down the Canyon View rd. until it ends and then bear right on the dirt road which wraps around the hill. The gap should be obvious at this point. At the base of the hill you follow it to your left, you should see some spots to set up camp near the firehidrant.
The gap has some sport routes and moe's valley is next door for some bouldering.

Thanks Kyle! We passed through but due to the heat we just kept heading north and found some camping near Beaver, UT. However, we were very impressed with the St. George area so your camping beta will prove useful for a future trip.

Where would be the best place to camp for a group of ten? It doesn't need to be near climbing, as we won't be doing any (school trip). We will be in a fairly large 13-passenger bus/plywood-death-box and will have a trailer in tow. We will just be stopping for overnight on our way back from L.A. to CO. Any recommendations?

I'd think Snow Canyon State Park is your best bet, they have group sites.

As you drive through the VRG (just after you cross into Arizona), there is only one exit, it is called "Cedar Pocket". Exit there and head northwest back over the freeway. The road will quickly turn to gravel, park and camp wherever you want. If it's in season, there will be climbers there, but be careful, they're the grumpy, aggro sport climber types, not the carefree, friendly trad climber types.
