Check out www.traildamage.com There's lots of trail reports for the area, ranging from mostly easy/moderate to very difficult. Other towns in the general vicinity would be Empire, Central City (follow hwy 119 north from Central City - there are lots of trails in this area as well), Keystone, Idaho Springs
I don't think the whole Jeep thing is as commercialized in this area as it is in the San Juans, but looks like there are potentially more trails here.
