Lots and lots of 4-wheeling in the area there. As mentioned, Traildamage.com is a great source. Also, the Mile-Hi Jeep Club met there in 2004 if you want some write-ups and such:

Not sure what sort of amenities folks will need for camping, but there are quite a few options in the area. Just a bit toward Denver is Idaho Springs, which has this one:

Idaho Springs also has Beau-Jo's, home of the Colorado Mountain Pie:

And there's whitewater rafting thereabouts, too.
I won't be into that neck of the woods until July, but after that should be good to go wherever.
